Most forex beginners spend their time looking for a better entry. Professionals spend theirs on risk, because risk is the only part of a trade you fully control. The 1% rule is the simplest framework for it: never risk more than about 1% of your account on a single trade. This guide shows the position-size formula, the maths behind why small risk per trade matters so much, and a worked example. It is education only; leveraged currency trading is high risk, and Indian residents should also read the rules on what they may trade.
The rule limits the amount you lose if your stop-loss is hit, not the size of the position. With a 10,000-dollar account, 1% is 100 dollars. You may open a large position or a small one, as long as hitting your exit level costs about 100 dollars. Some traders use 0.5% or 2%; the principle is to choose a small fixed percentage in advance and keep it.
Position size (in lots) = amount you will risk ÷ (stop distance in pips × pip value per lot)
For EUR/USD, one pip on one standard lot (100,000 units) is about 10 dollars. Example:
If your stop is wider, say 80 pips, the same 100-dollar risk allows only 0.125 lots. The stop goes where the trade idea is proved wrong, and the size adapts to it; you never move the stop to fit a size you want. Pip values differ by pair and change with exchange rates, so use your broker's calculator. See forex basics for the vocabulary.
| Risk per trade | Account after 10 straight losses | Gain needed to recover |
|---|---|---|
| 1% | about 90.4% of start (down 9.6%) | about 10.6% |
| 2% | about 81.7% (down 18.3%) | about 22.4% |
| 5% | about 59.9% (down 40.1%) | about 67% |
| 10% | about 34.9% (down 65.1%) | about 187% |
Ten losses in a row sounds extreme, but losing streaks happen even with a good method. At 1% risk, a bad streak is survivable; at 10% it ends the account. Leverage makes this worse, because it lets you take a position far larger than your risk budget permits.
The ratio between what you risk and what you aim to make sets the win rate you need to break even (before costs):
A higher reward target is not free, because it is hit less often. Spreads, commissions and slippage also push the true break-even higher, particularly around news. Plan for them using the economic calendar, which shows high-impact releases in IST.

It limits the amount you lose if your stop-loss is hit on one trade to about 1% of your account. You choose the position size so that distance to the stop multiplied by pip value equals that amount.
Position size in lots equals the amount you will risk divided by the stop distance in pips multiplied by the pip value per lot. For EUR/USD, one pip on a standard lot is about 10 dollars, so risking 100 dollars with a 40-pip stop gives 0.25 lots.
It feels small, but it keeps losing streaks survivable. Ten straight 1% losses cost about 9.6% of the account, while ten 10% losses cost about 65%. Many traders use between 0.5% and 2%, and the key is to fix the number in advance.
