//  Strategy Description (for TradingView Public Library & Users)
// ================================================================================
// © ArrowTrade
//
// A configurable Moving Average Crossover strategy designed for flexibility and
// API integration.
//
// Features:
// - MA Crossover Entries: Uses configurable Fast/Slow MA crossovers for signals.
// - Trend Filter: Optional longer-term MA filter to trade only with the trend.
// - Volatility Filter: Optional ATR filter to avoid low-volatility periods.
// - Volume Filter: Optional Volume filter to confirm entries with sufficient volume.
// - Stop Loss Options:
//     - Initial Volatility Stop (ATR-based)
//     - ATR Trailing Stop
//     - Break-Even Stop (activated by TP1 hit or ATR distance)
// - Take Profit Options:
//     - Two independent TP levels (percentage-based).
//     - Configurable partial close percentage at TP1.
// - Position Sizing: Fixed quantity per trade (adjustable).
//
// Intended Use:
// While configurable for various styles (scalping to trend-following by adjusting
// parameters), this strategy is built with API automation in mind. The clear
// entry and exit logic facilitates integration with external execution platforms
// via webhooks or other methods. Parameters can be tightened (shorter MAs,
// tighter stops/TPs, specific filters) for higher-frequency signals suitable
// for scalping.
//
// Disclaimer:
// Backtesting results are hypothetical and do not guarantee future performance.
// Market conditions change constantly. Always perform your own due diligence,
// forward testing, and rigorous risk management before trading live with any
// strategy. Ensure you adjust inputs like commission, slippage, and position
// size to accurately reflect your specific broker/exchange and risk profile.
