     }

This code is just an example about how to use the indicators buffer in building an expert advisor and It was not written to test the indicator ability to trade on real accounts.

I hope True Direction Oscillator (TDO)  to be a good trading tool for you. If you have any question send me a message and I will answer as soon as I am online.
