RiskLotSizer is a position sizing and risk management indicator for the cTrader platform. It enables traders to calculate appropriate trade lot sizes based on a selected percentage of their account equity. The indicator allows direct adjustment of Entry, Stop Loss (SL), and Take Profit (TP) levels on the chart, providing a visual and interactive way to plan trades in real time.

Key functionalities include automatic calculation and display of position size, estimated risk amount, reward amount, and risk/reward ratio (RR). It supports both Buy and Sell trade scenarios and features quick RR preset buttons for efficient trade setup. Risk and reward values are shown near the SL and TP lines, while a main panel summarizes the trade parameters clearly.

Additional features include line visibility toggling for a cleaner chart view and support for English and Japanese languages. RiskLotSizer is designed for discretionary and day traders seeking a streamlined method to size positions while maintaining consistent risk control. It supports various symbols such as BTCUSD, EURUSD, GBPUSD, NZDUSD, XAUUSD, NAS100, and USDJPY.
