The maximum drawdown limit in a 1-Step Breakout Evaluation is an equity limit based on your initial account balance. The maximum drawdown limit is (6%) of your initial account balance for a 1-Step Breakout Evaluation. Note that this is a static limit, in that your maximum drawdown limit does not change based on your demo account balance.
1-Step Evaluation example: You have a $100,000 1-Step Breakout Evaluation. The maximum drawdown is $6,000 = 6% of $100,000. If your demo account balance is $105,000, your maximum drawdown limit is still $94,000 = $100,000 - $6,000.
