Does anyone know of any add-ons or ways to configure Interactive Broker (IBKR) Chart Trader so that I can place my mouse on 2 points on my chart for entry and stop loss to automatically create my order position/share size based on risk $. For example if entry = 100, stop loss = 99.25 and my risk amount was $200, I would want it to calculate my share size of 266 shares for the bracket order.
