Max Risk Rule

Feature

Details

Limit

2%

Basis

Initial account balance

Calculation

Balance minus equity

Applies To

Total exposure across all open trades


How It Works

The max risk rule is not calculated per individual trade. Instead, it measures your total floating risk at any given time.

The rule checks the difference between:

  • Your account balance

  • Your current equity

If that difference exceeds 2% of the initial account balance, it is a breach.


Key Principle

This rule applies:

  • Across all open trades combined

  • Regardless of the number of positions

  • Regardless of the symbol being traded

Example 1 – Single Trade

Account size: 100,000
Max allowed risk: 2,000

You open a trade and your floating loss reaches:

  • Equity = 98,000

  • Balance = 100,000

Difference = 2,000 → Within limit

If equity drops to 97,900:

  • Difference = 2,100 → Breach

Example 2 – Multiple Trades

You have 3 open trades:

  • Trade 1: -800

  • Trade 2: -700

  • Trade 3: -600

Total floating loss = 2,100

  • Balance = 100,000

  • Equity = 97,900

Difference = 2,100 → Breach

Even though no single trade exceeded 2%, the combined exposure caused the breach.

Example 3 – Profit Then Exposure

Account grows to 103,000
Balance = 103,000

You open trades and floating loss becomes 2,100

Rule is still based on initial balance (100,000):

  • Max allowed = 2,000

Even though you are in profit overall:

  • This is still a breach

Example

Start of day:

  • Balance: 100,000

  • Equity: 101,000

Daily limit:

  • 101,000 - 3,000 = 98,000

Falling below 98,000 results in a breach.
