// Description: 
// The ENIGMA ENDGAME strategy leverages price action breakouts within specific kill zones (London and US sessions) to capture profitable opportunities. 
// The strategy uses dynamic position sizing based on account equity, precise entry logic via buy-stop and sell-stop orders, and robust risk management to achieve consistent profitability. 
// Features include:
// - Customizable kill zones for session-specific trading.
// - Risk management with dynamic position sizing based on user-defined percentages.
// - Multiple entry opportunities with lookback-based high/low tracking.
// - Automatic pending order cancellation to avoid stale trades.
// - Adjustable risk-reward ratios for optimal profit-taking.

// Define customizable kill zones for London and US sessions
