Position Sizer Order Assistant MT5 (MT5) — review, price and free alternatives

Position Sizer Order Assistant MT5 stands out because it does not make market calls; instead it standardizes risk application by translating a trader's percentage risk into precise lot sizes and margin implications on MetaTrader 5 charts.

The algorithm calculates lot size using account currency, stop loss distance in pips, and selected risk percentage, then displays the suggested size and expected monetary risk. Traders place orders visually by dragging entry and stop levels, and the assistant fills the order ticket consistently. In practice, Position Sizer Order Assistant MT5 handles forex majors, minors, and liquid CFDs well when volatility is moderate and spread costs are predictable. The tool is less suited for extremely illiquid assets or very wide spreads without manual adjustment.

Risk management is central to the design: fixed-percent risk per trade, immediate display of risk in account currency, and margin warnings help prevent inadvertent over-leveraging. Expected performance characteristics include lower position sizing variance, fewer execution errors, and improved adherence to risk rules rather than trading returns driven by the assistant itself. Konstantin Evseev designed the assistant to be transparent, data-driven, and compatible with typical MT5 broker setups, making it a practical choice for traders focused on process and discipline.

Position Sizer Order Assistant MT5 represents a moderate risk tool because it enforces conservative sizing rules but leaves directional decisions to the trader. The stop loss strategy is user-defined; the assistant calculates the monetary impact of the stop and adjusts lot size accordingly. Position sizing is percentage-based, typically recommended between 0.5 and 2.0 percent per trade for most retail accounts to limit exposure. Vulnerabilities include sensitivity to sudden spread widening and illiquid instruments where pip value and margin can deviate from expected. Recommended account size depends on instrument choice: $500 to $2,000 suits low-risk forex testing, while larger CFD exposures require higher balances to maintain margin buffers.

Install Position Sizer Order Assistant MT5 by copying the expert advisor file into the MetaTrader 5 Experts folder and restarting the platform. Attach the advisor to the chart and enable automated trading permissions if required for ticket placement.

Use brokers with low and stable spreads and standard lot sizing for best accuracy. Optimal timeframes are 5-minute to daily charts depending on your strategy. Test on demo accounts and run at least 500 historical trades or three months of forward testing to validate settings.
