Bollinger Wave EA
Overview
Bollinger Wave EA is an advanced automated trading system that combines grid trading methodology with Bollinger Bands technical analysis. The Expert Advisor identifies high-probability entry points by detecting price reversals at the extremes of the Bollinger Bands, strategically executing pending orders to capture market movements.
Core Strategy
Trading Logic
The Expert Advisor (EA) operates on the mean reversion principle, identifying oversold and overbought conditions through Bollinger Band analysis:
BUY Signals:
The price touches or approaches the lower Bollinger Band (overbold zone)
The price shows upward momentum (bounce off the lower band)
The price remains below the middle band, confirming oversold conditions
Places BUY STOP orders above the current price with predetermined spacing
SELL Signals:
The price touches or approaches the upper Bollinger Band (overbought zone)
The price shows downward momentum (retracement from the upper band)
The price remains above the middle band, confirming overbought conditions
Places SELL STOP orders below the current price with predetermined spacing
Grid Management System

Execution Automatic order triggering when the price reaches pending levels
