The Candle Range Theory (CRT) EA is a sophisticated automated trading system designed for MetaTrader 5. It operates on the principle of identifying significant range candles on a higher timeframe and trading the subsequent breach and reversal patterns. The strategy is structured around three key phases:

Accumulation Phase: This is the initial range candle where price consolidates, setting the high (CRT High) and low (CRT Low) boundaries. The EA detects this range and draws visual levels on the chart for reference.
Manipulation Phase: Following the accumulation, the price breaches one of the range extremes (low in bullish ranges or high in bearish ranges). The EA measures the depth of this manipulation and applies a filter to ensure it meets a minimum percentage threshold of the range size, avoiding false signals.

Distribution Phase: Upon reversal back into the range with confirmation from closed bars on a specified timeframe, the EA enters a trade in the direction of the reversal. It projects the distribution phase duration based on a percentage of the accumulation range time and draws visual rectangles for each phase.

The EA supports dynamic or static stop-loss and take-profit calculations, with options for trailing stops by points. It limits maximum positions per direction and uses a unique magic number for trade management. This strategy aims to capture high-probability reversals after liquidity grabs, optimizing for defined risk-reward ratios while providing visual aids for manual oversight.
