Expert Advisor: Trading with MA Channel Boundary Rollbacks

Related: e-trailing2: enhanced trailing stop expert advisor - another powerful expert for MetaTrader 4 traders.

This Expert Advisor (EA) utilizes moving average channel boundary data for trading decisions. When the price deviates from the moving average by a specified number of points, an order is placed in the direction of the moving average line. This EA is designed to generate profit, though it may be modest and requires a substantial deposit.

The core logic relies on a solid red line representing indicator data and a dotted red line indicating the channel boundary. Orders are opened when the price crosses these boundaries: a buy order at the lower boundary and a sell order at the upper boundary.

To ensure trade validity, an additional condition is applied. For a buy order to be placed on a candlestick touching the lower boundary, the low of the preceding candlestick must be above the lower boundary level. Conversely, for a sell order at the upper boundary, the high of the preceding candlestick must be below the upper boundary level.

The EA includes several plug-in modules to enhance its functionality:


The Turn Module

This module places pending limit orders at the stop loss level of the main order, in the opposite direction. It is intended for scenarios where the price continues to move away from the MA line after reaching the channel boundary.


The Step Down Module

This module adds orders in the direction of the main order, creating a grid of orders. This functionality was previously used in another system.


The Trade Time Module

This module restricts the trading times for the EA. It allows users to define a specific time interval during which the EA can open its primary orders. This does not apply to orders placed by the Step Down module.
