Maximum Trailing drawdown is the maximum your account can drawdown before you would hard breach your account. When you open the account, your Max Trailing Drawdown is set at 6% of your starting balance. This 6% trails your closed trading balance until you reach 5% profits in your account. Once you have achieved 6% in your account the max trailing locks in at your starting balance, and no longer trails your account.
Example: If your starting balance is $100,000, you can drawdown to $94,000 before you would violate the Maximum Trailing Drawdown rule. Then for example let's say you take your account to $102,000 in closed balance. This is your new high-water mark, which would mean your new Maximum Trailing Drawdown would be $96,000. Next, let's say you take your account to $110,000 in closed balance, which would be your new high-water mark. At this point, your Maximum Trailing Drawdown would be locked in at your starting balance of $100,000. So, regardless of how high your account goes, you would only breach this rule if your account drew back down to $100,000 (note, you can still violate the Daily Loss Limit). For example, if you take your account to $170,000, as long as you do not drawdown more than 5% in any given day, you would only breach if your account equity reaches $100,000.
