AcceleratorBot USDJPY H4 Strategy

The AcceleratorBot strategy is a conversion of the original MQL4 expert designed for USDJPY on the H4 timeframe. It blends trend strength from the Average Directional Index (ADX), momentum from the Stochastic Oscillator and multi-timeframe Acceleration/Deceleration (AC) values. Candlestick patterns are used as directional filters.
