Calculating MT5 Position Size from Risk and Stop Distance

Summary

The document describes a MetaTrader 5 utility for estimating lot size before a trade. A trader supplies either a risk percentage or a fixed amount, an account value, and a stop-loss distance; the calculator converts those inputs into a volume compatible with the broker’s symbol specifications. It accounts for tick value, tick size, and permitted volume limits.

Account value can be based on balance, equity, or a custom amount, and stop distance can be entered in points or as a price difference. The tool also reports basic risk and reward information and estimated margin. It is presented as a sizing aid, not a signal generator or trade executor. The document gives no examples, formula details, accuracy tests, or performance evidence, so it does not establish how the estimates behave across brokers or instruments.

Key ideas

• The utility calculates position volume from a chosen risk amount and stop-loss distance.
• It accounts for tick specifications and broker volume constraints.
• Account value may be based on balance, equity, or a custom input.
• Stop distance can be expressed in points or as a price difference.
• The tool provides estimated margin and basic risk-reward information but does not place trades or generate signals.
