LotCalc calculates lot size from your account balance, risk percentage, and stop-loss distance for MT5 on Windows and macOS — cTrader coming soon
Problems that affect position sizing accuracy and workflow quality
One incorrect position-size calculation can put more capital at risk than intended
Unreliable calculators interrupt the sizing workflow when you need a clear number
Buying separate tools for different platforms adds friction and recurring expenses
Built to make position-size calculations stable, repeatable, and easy to review before placing an order. LotCalc keeps the workflow simple: enter your risk settings, set the stop-loss distance, and review the calculated lot size manually.
Three steps on MetaTrader 5
Define your risk percentage once in the indicator settings
Use your chosen stop-loss distance as a calculation input
The position size updates in real time for manual review before any order
Built for MT5 users who value reliability
Single purchase covers MT5 now. cTrader support is on the roadmap.
Works seamlessly across operating systems with no platform restrictions
Designed with minimal moving parts so the sizing tool stays responsive.
Automatic calculation removes separate spreadsheet steps from position sizing
Keep the same user-defined risk percentage across repeated calculations.
Position size updates instantly as you adjust the stop-loss distance.
