What is Risk Management
Risk management is how you protect your trading account from losing too much money. It's the most important skill in trading.
Position sizing controls how much you can lose. Margin and leverage control whether you’re allowed to place the trade at all. They exist between you and the broker, not between you and the market.
Why traders fail:
- Poor psychology (emotions, discipline)
- Poor risk management
You can have a winning strategy, but without proper risk management, a few bad trades can wipe out your account. Risk management keeps you in the game long enough for your edge to play out.
Risk to Reward (R:R)
How much you're willing to risk compared to how much you could gain. Written as a ratio.
Examples:
- 1:2 R:R = Risking $100 to potentially make $200
- 1:3 R:R = Risking $100 to potentially make $300
The higher the reward, the better. A higher reward ratio means you can be wrong more often and still be profitable.
Why R:R Matters
| Risk:Reward | Win Rate Needed to Break Even |
|---|---|
| 1:1 | 50% |
| 1:2 | 33% |
| 1:3 | 25% |
| 1:4 | 20% |
With a 1:3 R:R, you only need to win 1 out of every 4 trades to break even. Win 2 out of 4 and you're profitable.
Profitability = Win Rate × Average Risk to Reward
You can have a low win rate and still make money if your winners are bigger than your losers.
Try it · Break-Even Win Rate
2 means you aim to make 2 for every 1 you risk (1 : 2).
Break-even win rate
33.3%
At 1 : 2, you need to win more than roughly 33.3% of your trades to have a positive result, before costs. Win less often than that and you lose money over time, however good the winners feel.
| Risk : reward | Break-even win rate |
|---|---|
| 1 : 0.5 | 66.7% |
| 1 : 1 | 50% |
| 1 : 1.5 | 40% |
| 1 : 2 | 33.3% |
| 1 : 3 | 25% |
| 1 : 5 | 16.7% |
This is the break-even point before spreads, commissions and slippage. Real costs push the win rate you need higher.
How was this calculated?
- Break-even win rate = 1 ÷ (1 + R) = 1 ÷ (1 + 2) = 0.3333 (33.33%)
The Minimum Standard
The minimum risk to reward ratio you should take is 1:2, ideally 1:3.
Anything less than 1:2 means you need to win more than half your trades just to break even - and that's hard to do consistently.
Try it · Risk : Reward
Sets the unit distances are shown in: pips for forex, points for everything else.
Risk : reward
1 : 2
You are risking 1 for the possibility of making 2. At this ratio you would need to win more than 33.3% of your trades to break even, before costs.
How was this calculated?
- Risk = |Entry − Stop| = |1.1650 − 1.1600| = 0.005 (50 pips)
- Reward = |Target − Entry| = |1.1750 − 1.1650| = 0.01 (100 pips)
- Risk : reward = Reward ÷ Risk = 0.01 ÷ 0.005 = 2
- Break-even win rate = 1 ÷ (1 + 2) = 33.33%
Stop Loss
A stop loss is an order that automatically closes your trade at a set price to limit your loss.
Where to place it: Your stop loss should be placed just beyond the point where your trade idea is proven wrong.
- If you're buying at support, your stop goes just below that support level
- If you're selling at resistance, your stop goes just above that resistance level
If price hits your stop, it means your analysis was wrong - and that's okay. The stop protected you from a bigger loss.
The Non-Negotiable Rule
You must always have a stop loss. This is non-negotiable.
Trading without a stop loss is gambling. One bad trade can destroy weeks or months of gains. A stop loss defines your maximum risk before you enter the trade.
You can get away without a take profit (though it's recommended). But a stop loss? Always. Every single trade.
Take Profit
A take profit is an order that automatically closes your trade at a set price to lock in your gains.
Where to place it: At a logical target where price is likely to reverse or stall:
- The next support/resistance level
- A previous high/low
- A measured move target (like the height of a pattern)
Why use one: It removes emotion from the exit. Without a take profit, you might hold too long and watch your profit disappear, or exit too early out of fear.
The entry, the stop loss and the take profit define the whole trade. Drag them and watch how the risk, the reward and the risk-to-reward ratio respond:

Grab any line, the entry, the stop or the target, and drag it. Or focus a line and use the arrow keys (hold Shift to move ten at a time).
Your account currency (USD) matches the currency this pair is quoted in, so no conversion was needed.
How was this calculated?
- Risk distance = |1.1650 − 1.1600| = 0.005 (50 pips)
- Reward distance = |1.1750 − 1.1650| = 0.01 (100 pips)
- Risk = distance × position × conversion = $100.00; reward = $200.00
- Risk : reward = 0.01 ÷ 0.005 = 1 : 2
Scaling out: A trade does not have to close at a single target. Closing it in stages turns several targets into one blended result:
Try it · Partial Profit
Only used if the stages total less than 100%. 0 is break-even; −1 is a full stop-out.
Converts the result into money.
Result of the whole trade
+2R
Closing in stages turned these targets into a single blended result of +2R. Closing everything at the first target (+1R) would have given +1R.
- 50% at +1R+0.5R
- 25% at +2R+0.5R
- 25% at +4R+1R
This assumes every target is reached. Scaling out lowers the result of a full winner but makes a trade easier to stick with; it does not change the risk taken at the start.
How was this calculated?
- 50% × +1R = +0.5R
- 25% × +2R = +0.5R
- 25% × +4R = +1R
- Total = +2R
The Maths of Trading
You don't need to be good at maths to trade, but you need to understand these basics.
Pips
A pip is the smallest standard price movement in forex. For most currency pairs, it's the fourth decimal place.
Example: If EUR/USD moves from 1.1000 to 1.1001, that's a 1 pip move.
Pips are how you measure:
- How far price has moved
- The size of your stop loss and take profit
- Your profit or loss on a trade
Note: In other markets (stocks, crypto, futures), the equivalent is called "points" or "ticks."
Fixed Value-Per-Pip
There is a fixed reference money-per-pip at 1.00 lot, defined per instrument × broker.
This is not optional — it’s how the market converts price movement into money. It doesn't need to be calculated manually, but it has to be understood conceptually: that it exists and where it comes from.
It answers the question: “If price moves by 1 pip on a 1.00 lot position, how much money changes?” “How much money is gained or lost when price moves by 1 pip on this contract size for this broker and instrument”
-
A lot tells you HOW BIG the contract is
-
Value-per-pip (or pip value) tells you HOW FAST money changes when price moves
-
Defined by instrument × broker
-
Shown in MT5 specs (via tick value / contract size)
-
Does NOT depend on your lot size
-
Fixed unless you change instrument or broker
Example (GBPUSD on most brokers):
- Reference money-per-pip at 1.00 lot = £10
This is the constant.
Try it · Pip Value
Advanced options
Standard forex lots are 100,000 units. Only change this if your broker differs.
Value of one pip
$10.00per pip
At 1 lots, every pip EUR/USD moves is worth $10.00 in your USD account. A 10-pip move is worth $100.00.
| Lots | Units | Per pip | Per 10 pips |
|---|---|---|---|
| 0.01 | 1,000 | $0.10 | $1.00 |
| 0.1 | 10,000 | $1.00 | $10.00 |
| 0.5 | 50,000 | $5.00 | $50.00 |
| 1 | 100,000 | $10.00 | $100.00 |
| 2 | 200,000 | $20.00 | $200.00 |
| 5 | 500,000 | $50.00 | $500.00 |
| 10 | 1,000,000 | $100.00 | $1,000.00 |
Your account currency (USD) matches the currency this pair is quoted in, so no conversion was needed.
How was this calculated?
- Pip size = 0.0001 (most pairs use the fourth decimal)
- Pip value in USD = 100,000 units × 0.0001 = 10 USD
Every trade also pays the spread: the gap between the price buyers pay and the price sellers receive. Widen it and watch what it costs at this position size:

Cost of the spread
$20.00
Buyers pay the ask, but an open position is valued at the bid. With a 2-pip spread on 1 lots at $10.00 per pip, the trade opens −$20.00 behind. Price has to move 2 pips in favour just to reach break-even.
| Spread | Cost at this size |
|---|---|
| 0.2 pips | $2.00 |
| 0.5 pips | $5.00 |
| 1 pips | $10.00 |
| 2 pips | $20.00 |
| 3 pips | $30.00 |
| 5 pips | $50.00 |
Spreads change constantly and differ by broker and account type. This shows the cost of a fixed spread you choose; it does not include slippage, swaps or other fees.
How was this calculated?
- Ask = Bid + Spread = 1.10000 + 2 × 0.0001 = 1.10020
- Value of one pip at 1 lots = $10.00
- Spread cost = 2 pips × $10.00 = $20.00
Contracts
Before moving to lots, contract sizes have to be understood.
Contract size answers this question:
“If 1.00 lot is traded, how many units does that represent?”
This is defined by:
- The market
- The broker (e.g. Vantage)
- Enforced by the platform (e.g. MetaTrader 5)
You do not choose this.
You do not change this.
The contract size never changes per instrument, per broker.
It is part of the instrument’s DNA.
In physics, you'd call it a physical constant.
Lots
What is a lot?
A lot is a multiplier. That's all. It’s a multiplier applied to a fixed contract size.
A lot is a ratio you adjust and scale to match your account size and risk according to a fixed quantity - contract sizes.
When thinking about lots in relation to pips, the point to remember is: risk-per-pip is NOT calculated from lot size. A known price-per-pip is SCALED down to match the risk-per-pip.
A “full contract size” is the definition of the instrument. A “lot” is how much of that contract you choose to trade.
Lot size controls how expensive each pip is. Lot size decides how sensitive your P/L is to price movement. Lot size directly determines notional value.
“Full contract” and “1.00 lot” are the same thing
Fundamentally, a lot (size), answers the question: “How many multiples (or fractions) of the contract size are being traded?” “If price moves by 1 pip on this trade, how much money changes?” “What lot size scales the reference money-per-pip at 1.00 lot down to £X per pip for this trade?”
For example, say the following is known:
- Risk = £100
- Stop loss = 50 pips
Target £/pip = Risk Amount ÷ Stop (pips)
Now a different question is asked:
“What lot size gives £2 per pip?”
That’s all lot size does.
It sets the risk value amount per pip of movement for the trade.
FUNDAMENTALLY, THIS IS WHAT "RISK PER TRADE" MEANS CALCULATING THE LOT SIZE IS WHAT IT ALL BOILS DOWN TO.
You never decide lot size first
You decide risk (amount) first, and lot size is just the result.
Standard lot sizes in forex:
| Lot Type | Size | Value per Pip (approx) |
|---|---|---|
| Standard | 100,000 units | $10 per pip |
| Mini | 10,000 units | $1 per pip |
| Micro | 1,000 units | $0.10 per pip |
The larger your lot size, the more money you make or lose for each pip of movement.
Notional Value
Imagine you "control" an apartment building worth £100,000. You don't own it. You just have a contract that says: "Any change in the building's value belongs to the contract holder."
- If the building value goes to £105,000, you just made £5,000 in "real" cash, even though you never actually had £100,000.
- If the value goes to £95,000, you owe £5,000.
The £100,000 is the "weight" of your trade. It's the reason why a tiny 1-pip move—which is a microscopic change in price—actually results in a £10 change in your account.
Your Profit and Loss is calculated ONLY on the Notional Value (£100,000).
So when people say:
“You are controlling £100,000”
They mean this and only this:
Your profit and loss is calculated as if the position were £100,000 in size.
The "£100,000" is just a notional value. It’s the size of the bet.
The market simply tracks the change in value of that £100,000. If the value goes up 1%, the broker credits your account with £1,000. If it goes down 1%, they take £1,000 from you.
This is why the word “control” is misleading.
You are not controlling money.
You are exposed to price movement.
You are trading real P/L, calculated from a reference size.
It is not "fake" money; it is Market Exposure.
Think of it this way (very literally):
- The market moves in price units
- Your account moves in money units
- The notional value is the exchange rate between the two
Notional value = Margin × Leverage
Example:
- You buy 1.00 Lot (Notional Value: £100,000).
- The price of the Pound goes up by 1%.
- Calculation: 1% of £100,000 = £1,000 Profit.
Look at what that means for your "real" money:
- You used £3,333 to make £1,000.
- That is a 30% return on your deposited money, even though the market only moved 1%.
If notional value were meaningless:
- Pip values wouldn’t scale
- Lot size wouldn’t matter
- Risk control wouldn’t work
But in reality:
- Change lot size → P/L speed changes
- Change stop → loss amount changes
- Change leverage → margin requirement changes
Leverage
Leverage is a rule the broker sets that answers this question: “How much of the contract’s notional value must you post as collateral?”
In other words: “How much of the trader's own money has to be put down to open this trade?” or more simply “How much notional exposure is allowed per £1 of margin?”
1:30 leverage is the typical leverage on major FX pairs
This means:
To control £30 of contract value, you must provide £1 of margin
Or flipped:
You must post ~3.33% of the contract value as margin.
Similar to to lot sizes, it is purely a multiplier.
- Leverage does not increase risk by itself.
- Leverage affects capital efficiency, not loss magnitude.
- Leverage does NOT increase your ability to trade — it increases the broker’s risk that you cannot pay.
Leverage determines:
- Maximum position size you’re allowed to open
- How much free margin you retain
- How much exposure you’re allowed to take for a given amount of your own money.
- Whether you get a margin call / stop-out before your stop is hit
This is how people blow accounts (and it's not because of leverage):
They:
- use big lot sizes
- lock too much margin
- leave no breathing room
Then:
- price moves a little
- losses eat their free money
- broker closes the trade early
Leverage has absolutely nothing to do with your £1,000 risk. The 1:30 leverage does not connect Risk to Margin; it connects Margin to Notional Value.
Leverage connects margin to notional value. Risk connects lot size to stop distance.
If you understand that Profit and Loss is calculated on the £100,000 Notional Value, then you realize that leverage is simply the "permission" to control a massive amount of money with a tiny amount of your own.
Leverage doesn't change how much you profit (that’s determined by your lot size), but it changes how much Free Margin you have left to survive price fluctuations.
Try leverage safely. This practice account lets leverage go from 1× to 30×. Move the market and watch what happens to the balance, in both directions:
Try it · Leverage Sandbox
The percentage the market moves while the position is open.
Account after the move
$900
−10% of the account
At 10×, $1,000 controls $10,000. A market move of −1% on a long position is a loss of $100 on that exposure: −10% of the account.
What the account controls
Account before and after
The same -1% move at every leverage
- 1×−1%
- 2×−2%
- 5×−5%
- 10×−10%
- 20×−20%
- 30×−30%
This simplified sandbox uses the whole account as margin. Real trading adds position sizing, stop losses, margin calls and stop-outs, spreads and costs. Leverage magnifies losses exactly as much as gains.
How was this calculated?
- Exposure = Account × Leverage = $1,000 × 10 = $10,000
- Profit or loss = Exposure × Market move = $10,000 × −1% = −$100
- Account impact = −$100 ÷ $1,000 = −10%
- Move that wipes out the account = 100% ÷ 10 = 10%
Margin
Money the broker locks as a deposit while a trade is open. You don’t lose it when you open the trade. It’s just “held” so you can’t use it for other trades
“How much money is locked while the trade is open?” “How much money must be locked to hold this notional exposure?”
The amount of your account balance the broker temporarily locks as collateral while the trade is open.
Important:
- It is not a cost
- It is not money you lose
- It is released when the trade is closed
- It has nothing to do with your stop loss
Margin is derived only from notional value and leverage.
It is the maximum pool your losses are taken from while the trade is open.
Risk tells you how much you lose if you’re wrong. Margin tells you how much pain you can survive before you’re forced out.
Free Margin
Money still available to absorb losses / open new trades Free Margin = Equity − Margin
Try it · Margin & Leverage
The full value of the position you want to control (units × price), in your account currency.
30 means 30:1 — every 1 of margin controls 30 of position.
Adds free margin, effective leverage and the impact of market moves on your account.
Margin required
$5,000.00
You control $100,000.00 while committing $5,000.00 of margin — 5% of the position. Margin is held by the broker as collateral; it is not a fee and is released when the trade closes.
| If price moves against you | You lose | Of your margin | Of your equity |
|---|---|---|---|
| −0.5% | $500.00 | 10% | 5% |
| −1% | $1,000.00 | 20% | 10% |
| −2% | $2,000.00 | 40% | 20% |
| −5% | $5,000.00 | 100% | 50% |
Leverage decides how much margin you must lock up. It does not change how much a price move earns or costs: that depends on your position size. Brokers also apply margin-call and stop-out levels that are not modelled here.
How was this calculated?
- Margin required = Position value ÷ Leverage = $100,000.00 ÷ 20 = $5,000.00
- Effective leverage = Position value ÷ Equity = $100,000.00 ÷ $10,000.00 = 10×
- Free margin = Equity − Margin = $10,000.00 − $5,000.00 = $5,000.00
Position Sizes
This is important psychologically.
Markets work in:
- Contracts
- Units
- Price movement
So you must:
- Decide risk value amount
- Decide stop distance
- Choose the contract size (lot) that converts price movement into that risk value amount
Fundamentally, money is not what is being traded. Price movement (on a contract) is.
Position sizing in trading is purely the calculation of "how much" is traded, according to predefined risk.
So if only 1% of the total account balance is to be risked, how much money is that? What value of money is at risk?
Risk Value Amount = Account Balance x (risk % / 100)
So if an account balance is £1000, and only 1% is to be risked, only £10 of value is at risk.
So then the ultimate question becomes: “If price moves against the trade from entry to stop, how "big" must the trade be so that the total money lost is only £100?”
It goes like this:
- Choose how much is acceptable to lose
- Choose where the trade is proven wrong (stop loss)
- That gives the £ per pip
- Set the knob of the trade that sets £ per pip
And the question of "how big must the trade be" or "the knob" is the core, underlying main mission...
Risk Per Trade
The rule: Risk no more than 1-2% of your account per trade.
This is the most important number in risk management.
Why 1%?
- If you lose 10 trades in a row (it happens), you've lost 10% of your account - painful but recoverable
- If you risk 10% per trade and lose 10 in a row, you've lost your entire account
So how do you calculate lot size?
In this light, every trade has only 4 for important inputs:
- Account balance (the total value of your account)
- Risk % (percentage of your account you're willing to risk - typically 1%)
- Stop-loss distance (The number of pips (for Forex) or points (for Indices/Gold) between your entry and your stop loss)
- Value of 1 pip per lot ()
That’s it. Nothing else matters when it comes to managing risk when trading.
Lot size =
Risk amount ÷ (Stop loss in pips × Pip value per lot)
Lot Size =
Money You Are Willing To Lose
÷
(Stop Loss In Pips × Money You Lose Per Pip)
Lot Size =
Risk Amount
÷
(Stop Loss (pips) × Pip Value of 1.00 Lot)
Contract Size Multiplier =
Money willing to be lost
÷
(Number of pips price can move against the trade × Money lost per pip on 1 full contract)
If your stop loss gets hit, you lose exactly $100 (1% of your account). No more, no less.
Try it · Position Size
You are risking $100.00 on this trade.
Advanced options
Standard forex lots are 100,000 units. Check your broker for other instruments.
Your size is rounded down to this. Most brokers allow 0.01 lots.
Your position size

Approximately 20,000 units
If your stop is reached, your estimated loss is $100.00, or 1% of your $10,000.00 account, excluding slippage and fees.
Your account currency (USD) matches the currency this pair is quoted in, so no conversion was needed.
How was this calculated?
- Risk amount = $10,000.00 × 1% = $100.00
- Stop distance = |1.1650 − 1.1600| = 0.005 (50 pips)
- Loss per unit = 0.005 = $0.005
- Units = $100.00 ÷ $0.005 = 20,000
- Lots = 20,000 ÷ 100,000 = 0.2, rounded down to 0.20
- Loss if stopped = 20,000 units × $0.005 = $100.00 (1% of the account)
When a position is built in several parts, the average entry is not simply the middle of the prices. Each part is weighted by its size:
Try it · Average Entry
Adds the open profit or loss on the whole position.
Average entry price
$11.3333
300 units in total
The whole position cost $3,400.00 for 300 units, so each unit cost $11.3333 on average. The plain average of the prices ($11) is different because more was bought at some prices than others.
Buying more as price falls lowers the average, but it also makes the position bigger. The risk grows with it: averaging down is not the same as reducing risk.
How was this calculated?
- Entry 1: 100 × $10 = $1,000.00
- Entry 2: 200 × $12 = $2,400.00
- Total cost = $3,400.00; total quantity = 300
- Average entry = $3,400.00 ÷ 300 = $11.3333
Summary
| Rule | Why |
|---|---|
| Always use a stop loss | Defines your maximum risk, protects your account |
| Risk 1-2% per trade maximum | Keeps you in the game after losing streaks |
| Minimum 1:2 risk to reward | Allows profitability even with lower win rates |
| Calculate position size based on stop loss | Ensures consistent risk across all trades |
Putting it all together: The Complete Mechanical Chain
- The lot = size of the engine
- The pip = how far the wheel turns
- The pip value = how fast your fuel burns
Bigger engine + same movement = more fuel burned.
Lot size sets exposure. Exposure sets margin (through leverage). Lot size also sets risk (through stop distance). Risk and margin are related only indirectly, via lot size.
Notional value is a measuring stick, not a pile of money. Margin is a deposit, not a cost. Risk is a rule, not a mechanism. Profit and loss are real and come from price movement × notional size.
You are not trading money. You are trading price movement, and money is calculated from it.
To keep this crystal clear, this example uses a £1,000 Risk and a 20 Pip Stop Loss. The money is followed through the four specific "gears" of the machine.
- YOUR GOAL (The Risk Management)
You want to lose exactly £1,000 if the market moves 20 pips.
- The Math: £1,000 ÷ 20 pips = £50.00 per pip.
- This is the "Pay Rate" you need your trade to have.
- THE CALCULATION (The Lot Size)
On GBP/USD, 1.00 Lot pays roughly £8.33 per pip (based on $10/pip divided by a 1.20 exchange rate).
- The Math: £50.00 (Needed) ÷ £8.33 (Standard Rate) = 6.00 Lots.
- This is the "Knob" you turn in MT5.
- THE NOTIONAL VALUE (The Market Exposure)
The market doesn't see your £1,000 risk; it only sees the weight of your 6.00 Lots.
- The Math: 6.00 Lots × £100,000 (Standard Contract) = £600,000.
- This is the "Notional Value." It is the total value of the "asset" you are now controlling.
- THE LEVERAGE & MARGIN (The Broker's Permission)
The broker sees you are controlling £600,000. Because Vantage UK uses 1:30 leverage, they require you to post 1/30th of that value as a security deposit.
- The Math: £600,000 ÷ 30 = £20,000.
- This is the "Margin." This is the money locked in your account.
The Relationship Table:
| Component | Value | The Mathematical Mechanic |
|---|---|---|
| Risk | £1,000 | Your chosen "Exit Penalty." |
| Stop Loss | 20 Pips | The distance to your exit. |
| Lot Size | 6.00 Lots | The multiplier needed to make 20 pips = £1,000. |
| Notional Value | £600,000 | The actual weight of 6.00 Lots ($6.00 \times 100k$). |
| Leverage | 1:30 | The "Divider" the broker uses for your deposit. |
| Margin | £20,000 | The 1/30th of the Notional Value. |
Risk management isn't exciting, but it's what separates traders who survive from those who blow up their accounts.
