Phidias PropFirm: EOD Drawdown Explained

Phidias PropFirm uses an end-of-day (EOD) trailing drawdown system that only calculates your maximum loss limit at the close of each trading day. This means you can experience significant intraday swings without immediately violating your drawdown limit, as long as you close the day within acceptable parameters.

Key Facts

The EOD trailing drawdown at Phidias PropFirm works by establishing a new drawdown floor at the end of each trading day based on your highest end-of-day equity value. Unlike real-time trailing drawdowns that update continuously throughout the day, this system only snapshots your account at market close. If your account grows, the drawdown floor moves up accordingly, but intraday fluctuations don't affect the calculation.

Here's how it works with concrete examples using Phidias account sizes: If you have a $100,000 account with a 10% drawdown limit, your initial floor is $90,000. Let's say after three profitable days, your EOD equity reaches $105,000. Your new drawdown floor becomes $94,500 (10% below $105,000). Importantly, if during the next trading day you're down $8,000 intraday to $97,000, you haven't violated the rule because it's still above your $94,500 floor. For a $50,000 account, the same principle applies - if you grow to $52,500 EOD, your floor moves from $45,000 to $47,250.

This rule particularly benefits swing traders and position traders who may experience significant intraday volatility but have solid end-of-day strategies. Scalpers and day traders also benefit since they can take larger intraday risks without immediately hitting drawdown limits. However, traders who hold losing positions overnight face the highest risk, as they can't recover intraday losses before the EOD calculation.

The most common mistake traders make is misunderstanding when the drawdown resets. Many assume that because it's calculated EOD, they can exceed their drawdown limit intraday without consequences. While true to an extent, if you end the day below your drawdown floor, you fail immediately. Another frequent error is not accounting for overnight gaps - a position that seems safe at market close might gap down overnight, causing an immediate failure when markets reopen. Traders also sometimes forget that weekends count as position holds, so Friday's close determines your Monday starting point. The key is managing your end-of-day equity carefully while taking advantage of the intraday flexibility this rule provides.
