Micro E-mini S&P 500 (MES) on Phidias PropFirm

Trading MES at Phidias PropFirm offers excellent flexibility with end-of-day trailing drawdown that doesn't penalize intraday equity swings. With up to 50 MES contracts allowed and no daily loss limits, traders can scale positions effectively while benefiting from the firm's trader-friendly policies and 80% profit splits.

Position sizing for MES at Phidias PropFirm requires understanding their end-of-day trailing drawdown system, which only adjusts your drawdown floor at market close based on your highest end-of-day equity. This structure is particularly advantageous for MES traders since the S&P 500 can experience significant intraday volatility without permanently raising your risk threshold. Unlike firms that use real-time trailing drawdown, you won't see your allowable risk shrink during temporary profit spikes within the trading day.

When sizing MES positions, calculate your maximum risk per trade based on your account size and risk tolerance. Since MES moves in $1.25 increments, a 10-tick stop loss equals $12.50 per contract, while a 20-tick stop equals $25.00. On Phidias PropFirm's larger accounts, you can afford wider stops or larger position sizes. The key advantage is that if you're profitable intraday but give back some gains before the close, your drawdown floor remains unchanged until end-of-day.

Phidias PropFirm's overnight position allowance is crucial for MES trading, as many traders prefer holding positions through economic announcements or earnings that occur outside regular hours. The firm's news trading permission also means you can trade MES during high-impact events like FOMC meetings or NFP releases without restriction. With no consistency rules or minimum profit targets, you can focus purely on profitable trading without artificial constraints.

Practical tips include using the end-of-day drawdown structure to your advantage by taking larger intraday positions when opportunities arise, knowing that temporary drawdowns won't immediately tighten your risk parameters. Monitor your positions carefully as the trading day closes, since that's when your new drawdown floor gets established. The $0 activation fee and daily payouts make Phidias PropFirm particularly attractive for consistent MES traders who want quick access to their profits.

On a $100,000 Phidias PropFirm account with standard drawdown limits, trading 1 MES contract with a 10-tick stop risks $12.50, representing just 0.0125% of account equity. This conservative sizing allows for multiple positions or wider stops while maintaining proper risk management.
