Risk per trade is the amount of your account you are prepared to lose if your planned stop-loss is hit.
For example:
Account = £10,000
Risk = 1%
£10,000 × 0.01 = £100
Your planned risk is £100.
Percentage risk keeps your risk proportional to your account.
If the account changes, your risk amount can change accordingly.
Account = £5,000
Risk = 1%
Risk amount = £50.
Account = £20,000
Risk = 1%
Risk amount = £200.
