Technical Indicator Overview

Ideal for traders seeking to balance risk and reward with a visually engaging interface.

​

Key Features 

• Risk-Based Position Sizing: Calculates position size based on a fixed risk amount and the distance between entry and stop-loss prices.

• Dynamic Price Level Visualization: Plots entry, stop-loss, and take-profit lines with customizable lengths and gradient-filled areas for clear trade zones.

• Real-Time Trade Dashboard: Displays critical metrics like position size, risk-reward ratio, and profit/loss progress in a sleek, customizable table.

• Themeable Aesthetics: Offers multiple color themes (e.g., Synthwave, Outrun, Lush) with vibrant long (profit) and short (loss) colors for intuitive analysis.

• Gradient Fill Effects: Enhances chart readability with optional multi-step gradient fills between price levels, reflecting trade direction and intensity.

​

Usage Guidelines 

• Long Trades: Set an entry price above the stop-loss; the indicator sizes the position and highlights potential profit (long color) and loss (short color) zones.

• Short Trades: Set an entry price below the stop-loss; the tool adjusts visuals and calculations accordingly for downward moves.
