The Exp_RangeExpansionIndex EA is based on the signals generated by the RangeExpansionIndex oscillator.

The signal is formed when a bar is closing if the indicator has broken through the overbought or oversold zone determined by the values of expert's input parameters:

input uint Up_Indicator_level=+60;  // Upper overbought level
input uint Dn_Indicator_level=-60;  // Lower oversold level

This Expert Advisor requires the compiled indicator file RangeExpansionIndex.ex5 in order to run. Place it to <terminal_data_folder>\MQL5\Indicators.

Note that the TradeAlgorithms.mqh library file allows using Expert Advisors with brokers who offer nonzero spread and the option of setting Stop Loss and Take Profit together with position opening. You can download more variants of the library at the following link: Trade Algorithms.

Default Expert Advisor's input parameters have been used during the tests shown below. Stop Loss and Take Profit have not been used during the tests.
