Money management — managing your funds and risk while trading.
The goal of money management: to help you keep the size of a possible loss under control and avoid putting your entire trading deposit at excessive risk.
Why does money management matter?
In trading, you can never know the outcome of a trade in advance. Even if a trading signal fits your system, the price may move in the opposite direction from what you expect.
That is why it is important to decide in advance what volume you will trade and what share of your deposit you are prepared to put at risk.
The key principle
Do not risk your entire deposit on a single trade.
What determines the size of a trade?
Position size depends on several factors:
- the size of your deposit;
- the acceptable risk per trade;
- the Stop Loss level;
- the position volume (Lot).
The larger the position, the larger both the potential profit and the potential loss can be.
That is why you can’t simply pick the largest trade volume available.
Why it is important to account for risk
Price changes affect the financial result of a trade. That is why, before opening a position, you determine the acceptable risk and the position size that matches it.
Stop Loss and money management
Stop Loss (SL) — one of the risk management tools.
It sets in advance the level at which the trade will be closed if the price moves against you.
This lets you cap a possible loss ahead of time instead of leaving the trade unmonitored.
How does this work in practice?
Imagine you have a certain amount in your trading account.
Before opening a trade, you need to understand:
Deposit → acceptable risk → position size → Stop Loss
In other words, you first determine the acceptable level of risk, and only then choose the trade volume.
A short example
Position size is determined based on the distance to the Stop Loss and the specifics of the trading instrument. If even the smallest available volume would put your risk above the limit you set, you should not open that trade.
From risk amount to trade volume
The trade volume depends on the amount you are prepared to lose on a single trade and on the distance to the Stop Loss.
To calculate it, you need your deposit, your risk, the Stop Loss and the instrument’s parameters.
You can calculate the position size for your trade with the calculator below.
Calculate the volume for your trade
Enter your own numbers. The calculator shows not only the result but every step, so you can repeat the same actions by hand.
Where to find the point value
In MetaTrader 5, open the list of instruments, click the one you need and choose the contract specification. It shows the contract size, the minimum and maximum volume and the volume step. The point value depends on the instrument, the contract size and your account currency, so you can’t plug in a “typical” number — check it for your own account.
For pairs such as EURUSD, GBPUSD, AUDUSD and NZDUSD, with a USD account and a standard contract of 100,000, the point value is usually $10 per lot. For other instruments, the value depends on the current exchange rate, so you need to check it in the terminal.
This is a training calculation. It shows how to go from a risk limit to a volume and is not a recommendation to open a trade.
The main rule
Do not increase your trade volume just because you want a bigger profit.
A larger volume also increases the potential loss.
Money management exists precisely to keep your trading under control even through several losing trades in a row.
Check yourself
Deposit: 500 dollars. Risk per signal: 2%.
How many dollars are you prepared to lose on this signal?
Acceptable loss = deposit × risk percentage.
500 × 2% = 500 × 0.02 = 10 dollars.
This is the upper limit of the loss on the signal, not the amount you need to put into the trade.
Common mistake. Treating 2% as the amount you need to put into the trade. 10 dollars is the loss limit, not the position size.
Deposit: 1,000 dollars. Risk: 2%. Distance to the stop loss: 40 points. Point value: 10 dollars per lot.
What volume in lots keeps the risk exactly within the limit?
Acceptable loss: 1,000 × 2% = 20 dollars.
Loss per lot with this stop: 40 × 10 = 400 dollars.
Volume: 20 ÷ 400 = 0.05 lots.
Round down to the 0.01 step — here the value is already exact.
The order is always the same: first the limit in money, then the loss per lot, and only then the volume.
Common mistake. Dividing the limit by the distance to the stop and forgetting the point value: 20 ÷ 40 = 0.5 lots — ten times more than allowed.
Deposit: 100 dollars. Risk limit: 2%, which is 2 dollars. With your stop, the minimum volume of 0.01 lots gives a loss of 10 dollars.
What should you do?
In short
- First determine the acceptable risk, then the trade volume.
- Acceptable loss = deposit × risk percentage.
- Volume = acceptable loss ÷ (distance to the stop × point value), rounded down.
- If even the minimum volume exceeds the limit, the trade is not opened.
- A larger volume increases both the possible profit and the possible loss.
