Lot by Risk - cTrader is a trading robot (cBot) designed to help traders manage position risk effectively. It enables users to set customizable risk percentages (e.g., 1%, 0.5%, 0.25%, 0.12%) and select a default risk level. The cBot visually displays the risk-to-reward ratio based on user-defined entry, stop loss, and take profit lines drawn directly on the chart.

Key features include interactive trading lines for Entry, Stop Loss (SL), and Take Profit (TP) that can be drawn and adjusted on the chart using configurable hotkeys (default: E for Entry, S for SL, T for TP). The cBot automatically calculates appropriate lot sizes according to the selected risk percentage and updates a trading panel that shows current trade settings along with risk and profit amounts.

The trading panel offers options to show, hide, reset lines, and can be minimized or maximized for better chart management. This tool supports multiple markets including Forex, Indices, Commodities, Crypto, and Stocks, providing a visual and interactive interface to enhance risk management during trading.
