What is money management in forex?

Money management in forex is a written set of rules for how much of your trading account you risk, when you stop trading, and which money you keep out of it. It covers the account over months and years, while your strategy picks the trades.

It builds on two earlier lessons. Position sizing works out the lot size for a single trade, and scaling in and out covers how risk changes while a trade is open. This lesson sits above both: it decides the amounts those lessons use, and the limits that stop you trading when they have been reached. Together with the trading plan, it is the business side of trading.

Definitions

• Risk capital: money set aside for trading, separate from living costs, savings and debts.
• Fixed-fractional risk: risking the same percentage of your current balance on every trade.
• Drawdown: the fall in your account from a previous high, in money or as a percentage.
• Daily loss limit: the total loss in one day after which you open no new trades.
• Monthly loss limit: the total loss in one month after which you stop trading until your review.

Why does money management matter?

Money management matters because every trader has losing runs, and capital that has been lost cannot be traded. Capital rules decide how much one bad stretch can cost: in the worked example below, ten straight losses at 1% per trade cost 9.56% of the account, while the same run at 5% costs 40.13%.

Written rules help in a second way. Decisions about limits are easier to make before a loss than after one, when you are more likely to want to win it back. The pre-trade risk checklist applies these limits trade by trade.

What is risk capital, and what stays out of your account?

Risk capital is money set aside for trading, separate from what you need for living costs, savings and debts, and it is the only money that belongs in a leveraged trading account. Treat it as the business's working capital: a fixed, written amount with its own rules for adding to it and taking money out.

Four questions to answer in writing, before any deposit:

1. How much is the account's capital, and where does it come from?
2. What drawdown triggers a pause and a review?
3. At what point will I stop, rather than add?
4. How will I know I have reached that point?

The answers go into the plan with the date.

How does fixed-fractional risk work during a losing run?

With fixed-fractional risk you risk the same percentage of your current balance on each trade, so after a loss the money at risk, and the position size, become smaller. The rule adjusts itself: a losing run shrinks your position without you having to decide to cut it. The lot-size formula is the one in the position sizing lesson.

Worked example: ten losses in a row

This is a synthetic example, using 1% for easy arithmetic. A synthetic account of $5,000 risks 1% on the EURUSD currency pair with a 25-pip stop. One lot is worth $10 per pip, so the stop costs $250 per lot. Assume every trade is stopped out and loses exactly the planned 1%.

Each balance is $5,000 × 0.99 to the power of the number of losses. After ten straight losses the account is down $478.09, or 9.56%. The size of the next trade has fallen from 0.20 to 0.18 lot without anything being changed.

How does fixed-fractional compare with a fixed money amount?

A fixed money amount keeps risking the same sum as the account shrinks, so its share of the account grows after losses, while a fixed percentage keeps its share constant. Using the same ten losses:

After ten losses of exactly $50 the balance is $4,500, and the same $50 is now a larger bite. The difference is small over ten trades; it widens as losses continue.

Why does the percentage you choose matter so much?

The percentage you choose decides how deep a losing run can go, because losses compound against a shrinking balance. The same ten losses at 5% per trade leave $5,000 × 0.95 to the power of 10, which is $2,993.68 and a fall of 40.13%.

The last column is arithmetic, not a target: gain needed = loss ÷ (1 − loss). A loss of 9.56% needs 10.57% to undo, and a loss of 40.13% needs 67.02%, because the gain is earned on a smaller balance. This recovery asymmetry is why large drawdowns are so hard to reverse. The surviving drawdowns lesson covers how skilled traders handle one, and the performance metrics lesson shows how to measure it.

Work out your recovery

How do daily and monthly loss limits work?

A daily loss limit is a fixed amount of loss, set in advance, after which you open no new trades that day; a monthly limit does the same for the month. They stop a bad day from becoming a bad month, because the decision to stop has already been made.

Pick the amounts when you write your plan, in money so there is nothing to calculate under pressure. On the same synthetic $5,000 account:

At $50 of risk, three stopped-out trades reach the daily limit of $150. For the rest of that day the platform stays closed. If losses over the month reach $300, trading stops until the review described in the trade review cycle lesson, and any change to the plan is made then, not mid-month.

Count open trades too. A limit that ignores floating losses lets a position that is still open take you past it. If you scale in, the added volume raises your total risk; the scaling lesson shows how to recalculate it.

How do withdrawals fit into money management?

A withdrawal lowers your balance, so under fixed-fractional risk it lowers the money at risk and the position size on the next trade. Decide in advance when and how much you will withdraw, so it is a rule and not a reaction. Withdrawing moves your own money out of the business on a schedule you set.

Take the $5,000 account. After a withdrawal of $500 the balance is $4,500. One percent is $45, and on a 25-pip stop that is $45 ÷ $250 = 0.18 lot.

Withdrawals also change margin. According to MetaTrader 5 Help, free margin is equity minus margin, and margin level is equity divided by margin times 100. With equity of $1,000 and $400 of margin, the margin level is 250% and free margin is $600. Take out $300 and equity is $700: the margin level is 175% and free margin is $300. A plan can say that withdrawals happen when no positions are open, so they cannot reduce the margin level of a live trade. Check your account terms for how withdrawals are processed. The margin call and stop-out lesson explains what happens as the margin level falls.

Why should you never add money to recover losses?

Adding money to recover losses means increasing the capital at risk after the plan has already lost, which turns a limit into a starting line. The plan said where to stop. A top-up moves that line, and it can be followed by bigger trades to win the money back, the pattern in the revenge trading lesson.

Three rules keep it out of the account:

• No borrowed money, ever. If the funds are owed to someone, they are not risk capital.
• No top-ups to return to a previous balance. If the balance is below the old level, the position size follows the balance.
• A new deposit is a plan change. It is made on review day, from money that qualifies as risk capital, and written into the plan with the date.

Reaching a limit is not a failure of the plan. It is the plan working: it has stopped the loss from growing.

What else does a capital plan need to account for?

A capital plan also needs to account for gaps and slippage, minimum lot size, trading costs and the effect of smaller positions, because none of them is in the risk percentage. Each one changes the real money at risk, so each gets its own line in the Capital section of your plan.

• Gaps and slippage: a stop can fill at a worse price after news or over a weekend, so the real loss can exceed the planned one. See the stop loss lesson.
• Minimum lot size: on a small balance, 0.01 lot may already risk more than your percentage, so check that the smallest size fits before you take the trade.
• Smaller size works both ways: after a drawdown the same winning trade earns less, because the position is smaller, and size grows back as the balance does.
• Costs: spread, commission and swap are not in the percentage, so count them in your results.
• Sample size: judge capital rules and methods over many trades, not ten.

Try it on demo

On a MetaTrader 5 demo account, write a one-page Capital section for your plan: your chosen risk per trade, a daily and a monthly loss limit in money, a withdrawal rule, and one line saying you never add money to recover losses. Date it. Then trade the demo for two weeks and use the position size calculator to resize each trade from the current balance. Note in your journal each time you hit a limit and what you did.

What is the difference between money management and risk management?

Money management covers your whole trading account over time, including risk capital, loss limits and withdrawals, while risk management covers the risk on each trade. Position size and stop loss are risk management; deciding when you stop trading for the day or the month is money management.

How much of my account should I risk per trade?

Choose a fixed percentage in advance, write it in your plan and apply it every time. The examples here use 1%, and the choice matters: ten straight losses cost 9.56% of the account at 1% per trade and 40.13% at 5%.

What is a daily loss limit in trading?

A daily loss limit is a loss amount, set in advance, after which you open no new trades that day. On a $5,000 account, a limit of 3% of the opening balance is $150, which three stopped-out trades of $50 would reach.

Should I add money to my trading account after losses?

No, adding money to recover losses puts more capital at risk after the plan has already lost, and it can lead to larger trades to win the money back. Position size should follow the balance you have. A new deposit belongs in a planned review, from risk capital only.

What is risk capital?

Risk capital is money set aside for trading, separate from what you need for living costs, savings and debts. Rent, bills, emergency savings and borrowed money do not qualify. Write the amount into your plan with a date, and treat any new deposit as a plan change.
