Close prices array unavailable to compiler

Suggests to me that there is a function called Close which returns the double of the price of the candle specified as an integer argument.

Great. And from the crumb, I see

It's part of the Standard lib. So why is my compiler not finding it, or any other function under CExpert?

I specify

#include <Expert\CExpertBase.mqh>

at the top of my EA, but compiler can't find the header find, and nor can I.

Anyone know?

Looks like I have to not specify the C.

#include <Expert\ExpertBase.mqh>

works.

But then it gives me a massive number 1.7...e+308. I'll use CopyClose instead.

Right, there is a typo in the documentation.

#include <Expert\ExpertBase.mqh>

works.

Yes it's better if you use the class only for these function.
