Calculating Trade Risk, Reward, Margin, and Position Value in MT5

Article MQL5 code base

Summary

This document describes an MT5 utility for estimating the potential risk and reward of a planned trade. Inputs include entry, stop-loss and take-profit prices, lot size, and direction; the calculator estimates possible loss and profit, account risk percentage, and reward-to-risk ratio. It supports buy and sell positions and lets the user base account risk on balance, equity, or a custom amount.

The utility also estimates margin and position value and assigns a simple risk classification. It is described as a fast calculation aid for any symbol, not as a signal generator or trading system, and it does not execute orders. The supplied text explains its intended functions but offers no formulas, accuracy checks, instrument-specific assumptions, or performance evidence. Traders would need to confirm how contract specifications, costs, currency conversion, and margin rules are handled before relying on its estimates.

Key ideas

  • The calculator estimates potential profit and loss from trade prices, size, and direction.
  • It expresses possible loss as a percentage of a selected account value.
  • It provides reward-to-risk, margin, and position-value estimates alongside a risk category.
  • The tool supports both buy and sell scenarios across symbols in MetaTrader 5.
  • The description provides no calculation details or validation evidence, so estimates depend on the tool's assumptions.
