The 3-5-7 rule is a risk management framework used by some traders to control losses and preserve capital. It isn’t a universal trading rule, but a commonly cited guideline.

3. 7% Rule – Maximum Drawdown Before Reviewing
Example
Important Note

Here’s what each number represents:

1. 3% Rule – Risk per Trade

Don’t risk more than 3% of your total trading capital on a single trade.

If your account is $10,000, the maximum loss on one trade should be $300.
Your position size and stop-loss should be calculated so that, if the stop-loss is hit, you lose no more than 3%.

2. 5% Rule – Total Exposure

Don’t allocate more than 5% of your account to a single position or closely related positions.

The idea is to avoid concentrating too much capital in one stock, sector, or trade idea. Even if you’re confident, diversification helps reduce the impact of unexpected events.

3. 7% Rule – Maximum Drawdown Before Reviewing

If your account falls by 7% (or if a trade moves against you by around 7%, depending on the version of the rule), stop trading temporarily and review your strategy.

This means:

Analyze what went wrong.
Check whether market conditions have changed.
Avoid trying to “win it back” through emotional trading.

Example

Suppose you have a ₹5,00,000 trading account.

3% risk per trade: Maximum loss = ₹15,000.
5% maximum position size: Avoid putting more than ₹25,000 into a single position (or follow your own risk-based position sizing if you use leverage).
7% drawdown: If your account drops to ₹4,65,000, pause and reassess before continuing.

Important Note

There are multiple versions of the 3-5-7 rule circulating online. Some traders interpret the numbers differently—for example, using 7% as a stop-loss per trade instead of an account drawdown. There is no official or universally accepted “3-5-7 rule.”

The underlying principle is consistent across versions:
