// Volatility Momentum Breakout Strategy
//
// Description:
// This strategy is designed to capture significant price moves by combining a volatility breakout method
// with a momentum filter. Volatility is measured by the Average True Range (ATR), which is used to set dynamic
// breakout levels. A short‑term Exponential Moving Average (EMA) is applied as a trend filter, and the Relative
// Strength Index (RSI) is used to help avoid entries when the market is overextended.
// 
// Signal Logic:
// • Long Entry: When the current close is above the highest high of the previous N bars (excluding the current bar)
//   plus a multiple of ATR, provided that the price is above the short‑term EMA and the RSI is above 50.
// • Short Entry: When the current close is below the lowest low of the previous N bars (excluding the current bar)
//   minus a multiple of ATR, provided that the price is below the short‑term EMA and the RSI is below 50.
// 
// Risk Management:
// • Trades are sized to risk 2% of account equity.
// • A stop loss is placed at a fixed ATR multiple away from the entry price.
// • A take profit target is set to achieve a 1:2 risk‑reward ratio.
// 
// Backtesting Parameters:
// • Initial Capital: $10,000
// • Commission: 0.1% per trade
// • Slippage: 1 tick per bar
//
// Disclaimer:
// Past performance is not indicative of future results. This strategy is experimental and provided solely for educational
// purposes. Always backtest and paper trade before any live deployment.
