Frequently Asked Questions
What is Apex Trader Funding's daily loss limit?
Apex Trader Funding's daily loss limit is not enforced as a percentage (check dollar limits per account size). For the $25,000 account, the daily limit is based on the trailing drawdown floor.
What drawdown type does Apex Trader Funding use?
Apex Trader Funding uses trailing intraday (floor moves with every tick). The floor moves up in real-time as your equity reaches new highs during the session.
How do I calculate position size for Apex Trader Funding?
Divide your maximum risk per trade (a fraction of your daily loss limit) by your stop loss distance in pips multiplied by the pip value. For example, on a $25,000 account with a $1,500 daily limit, risking 1% of that limit gives you $15 risk per trade.
What is the safest position size for Apex Trader Funding?
Most successful prop firm traders risk 0.5-1% of their daily loss limit per trade. On Apex Trader Funding's $25,000 account, that means risking $8 to $15 per trade. This allows multiple trades per day without approaching the daily limit.
