If you're looking to level up your trading game, the Exp_Delta_WPR Expert Advisor (EA) is worth your attention. This EA operates on the principle of the Delta_WPR indicator, specifically triggering trades when the indicator's histogram changes color to either blue or orange at the close of a bar.
To get started, make sure you have the compiled indicator file named Delta_WPR.ex5. You’ll need to drop it into your terminal_data_folder/MQL5/Indicators directory for everything to work seamlessly.
One thing to keep in mind: the TradeAlgorithms.mqh library is essential if you want to use EAs with brokers offering a nonzero spread. Plus, it allows you to set Stop Loss and Take Profit levels right when you open a position. You can find more variations of this library at this link: Trade Algorithms.
For the tests showcased below, we used the default input parameters of the Expert Advisor. Notably, Stop Loss and Take Profit settings were not included in these tests.
