The Exp_Delta_WPR Expert Advisor is based on the Delta_WPR indicator color change. A signal to perform a deal is formed at the close of a bar if the color of the indicator histogram changes to trend blue or orange.
This Expert Advisor requires the compiled indicator file Delta_WPR.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.
