Error with trading algorithm in HighLowSignal EA

[RaphaAmin]

Hi folks, 

 I'm struggling with an error on the following EA: https://www.mql5.com/pt/code/2314?

It uses the tradealgorithms.mqh and returns the following error: (): Incorrect volume for a trade request structure

Searching the code I realized that the error is caused by a Volume <= 0. But I still didn't get why it happens.

All I want is to use the HighLowSignal indicator to trade for me.

 

Thanks in advance.
