MyFXRoom Position Size Calculator EA (MT5) — review, price and free alternatives

This review of MyFXRoom Position Size Calculator EA in 2026 evaluates real-world performance and delivers an independent analysis of what the tool offers to MT5 traders. MyFXRoom Position Size Calculator EA stands out because it separates position sizing from trade decision-making: traders maintain full control of entries and exits while the EA computes the exact lot size and submits orders to match predefined risk rules. The developer, Darren Graham Pallatina, focuses on robust, transparent sizing logic rather than black-box signal generation, and the EA logs each calculation for later review.

The algorithm converts stop-loss distance to monetary risk using ATR-adjusted pip values, account equity and user risk percentage, then rounds lots to broker minimums and current margin requirements. In practice this means the EA excels in trending and range-bound Forex sessions where stop placement is clear and spreads remain stable. MyFXRoom Position Size Calculator EA handles multiple symbols and timeframes with consistent logic, but like all tools it is vulnerable to high volatility news spikes and illiquid exotic pairs. The risk management approach is explicit: define risk percent, define stop loss in pips, and the EA enforces the computed lot size to keep drawdown predictable. Expected results are steady position-level risk control, fewer sizing errors, and improved consistency across multiple trades when traders follow documented stop placement rules.

The risk profile for MyFXRoom Position Size Calculator EA is moderate because the EA enforces user-defined risk limits but does not control entry timing. Stop loss strategy is entirely trader-defined; the EA translates that stop into a lot size consistent with the chosen percent risk. Position sizing follows percent-of-equity logic with ATR adjustments for pip value, which keeps trade risk consistent across varying volatility. Vulnerabilities include news spikes, weekend gaps and high-spread conditions that can blow through modeled stops; exotic pairs with low liquidity require larger margins and wider stops. Recommended account size depends on pair set and leverage, but a conservative guideline is $1,000 to $5,000 to allow meaningful lot increments without excessive leverage. MyFXRoom Position Size Calculator EA helps enforce risk discipline but cannot eliminate execution risk inherent in markets.

Install the MyFXRoom Position Size Calculator EA by copying the EA file into the MT5 Experts folder, restarting MT5, and attaching the EA to the desired chart. Configure key parameters: risk percentage per trade, minimum and maximum lot limits, rounding rules to broker lot steps, and ATR lookback for volatility conversion. Use STP or ECN brokers with competitive spreads and stable fill policies for best results. Recommended chart timeframes are H1 and H4 for discretionary entries; lower timeframes may increase slippage. Test thoroughly with forward demo trading and backtest period that includes high-volatility events to validate settings before going live.
