The Exp_Bezier Expert Advisor is based on the change in the direction of a universal Bezier curve. A signal for a transaction forms when a bar is closing, provided that the curve direction has changed.

Proper operation of the generated Expert Advisor requires the compiled indicator file Bezier.ex5 to be placed in terminal_data_directory\MQL5\Indicators.

Tests shown below were run using the default input parameters of the Expert Advisor. Stop Loss and Take Profit were not used during the tests.
