PTrader is a cBot for the cTrader platform designed to assist traders in managing position sizes and risk through visual stop-loss and take-profit levels on the chart. It operates exclusively with market execution orders, not supporting limit or stop orders. Users can set a stop-loss level directly on the chart, and the cBot calculates position size based on a customizable risk percentage of account equity or balance. The take-profit level is automatically determined using a user-defined risk-to-reward ratio.

Key features include customizable risk management options such as risk percentage, risk type (equity or balance), and risk-to-reward ratio. Visual elements like default stop-loss points, line width, style, and distinct colors for stop-loss and take-profit lines can be adjusted for clarity. Hotkeys enable quick toggling of line visibility and fast market order execution with predefined risk parameters. Additionally, info text layout and alignment on the chart are customizable for better readability.

PTrader aims to help traders maintain consistent risk management by integrating position sizing and risk controls visually and interactively within the cTrader environment.
