Understanding Daily Drawdown: Maximum Equity vs End-of-Day Balance
One of the most important rules in any prop firm challenge is the daily drawdown limit. While many firms advertise the same percentage, the way they calculate it can vary significantly—and that difference can have a major impact on your trading.
There are two common methods: Maximum Equity Drawdown and End-of-Day (EOD) Drawdown.
Maximum Equity Drawdown
With this model, your daily loss limit is calculated based on your highest account equity reached during the trading day. As your profits increase, your allowable loss threshold moves up as well.
For example, if you start the day with a $100,000 account and make $3,000, your account reaches $103,000. If the firm has a 5% daily drawdown, your new loss limit is now based on that higher equity level. A sharp reversal later in the day could violate the rule even if your account remains above the original starting balance.
This method requires strict risk management, especially when holding profitable trades.
End-of-Day (EOD) Drawdown
EOD drawdown is generally considered more trader-friendly. The daily loss limit is based on your account balance at the close of the previous trading day.
Using the same example, if your prior day’s closing balance was $100,000, your daily loss limit remains fixed throughout the entire day, regardless of any unrealized or realized gains during the session.
This provides greater flexibility and reduces the risk of accidentally breaching limits after giving back intraday profits.
Why It Matters
Two prop firms may offer identical drawdown percentages, but the actual trading experience can be completely different. Traders who prefer active intraday strategies often favor EOD-based firms because they offer more breathing room.
Before purchasing any challenge, always understand exactly how the daily drawdown is calculated. It could be the difference between passing your evaluation and failing unexpectedly.
