Ross Hook

[[Deleted]]

With the help of the Forex Strategy Builder Software I've developed an strategy with the indicator "Ross Hook".

I got the open source code of this indicator on there website but unfourtunatly I don't know how to convert it to an ".mq4".

Here is the complete code:

Is there a way to convert it?

Someone has already done that. There might be other implementations around the net, too. I suggest you look into whether these can be adapted to your needs.

I'm not aware of any some_other_language-to-mql4 conversion tools; there probably are some out there, but coding yourself is so much more fun. :)
