// Multi-Indicator Swing Trading Strategy [TIAMATCRYPTO]v6
// ====================================================================================
// DESCRIPTION:
// This strategy uses a combination of technical indicators to identify swing trading
// opportunities in various markets. The default settings are optimized for daily
// timeframes on cryptocurrency and forex markets.
// 
// RECOMMENDED DEFAULT SETTINGS:
// - Trading direction: Both (performs well in trending and ranging markets)
// - Position size: 5% (conservative position sizing to manage risk)
// - Stop Loss: 2% (conservative risk management for capital preservation)
// - Take Profit: 4% (realistic profit target with 1:2 risk-reward ratio)
// - Initial capital: $10,000 (realistic starting account size)
// - Timeframe: 2m (best performance on 2m charts)
// - Testing period: 2021-2033 (provides sufficient sample size of trades)
// ====================================================================================
