Add Draggable SL/TP Lines with Real-Time Position Sizing Calculator

Implement Interactive Stop Loss and Take Profit Lines with Pre-Trade Position Sizing.

Users should be able to place draggable Stop Loss and Take Profit lines directly on the chart before executing trades, with the system automatically calculating the appropriate lot size and dollar value based on the selected risk levels. This feature would allow traders to visually set their SL and TP levels by dragging lines to desired price points on the chart, while a real-time calculator displays the corresponding position size, potential profit/loss amounts, and risk percentage based on their account size and risk management settings. This interactive pre-trade planning tool would enhance risk management, improve trade execution accuracy, and provide traders with immediate visual feedback on their trade setup before committing to the position.
