ReverseLong() ReverseShort()

[enzoe]

Hallo, I'm not able to use the following methods ReverseLong() ReverseShort().

I am creating a custom EA, and I have include the following instruction inside:

#include <Expert\Expert.mqh>

CExpert           ExtExpertTrade;

but the ReverseLong() or ReverseShort() method is not accessible (example using ExtExpertTrade.ReverseLong(..))

can anybody give an example to hos is possible call the previous virtual function of CExpert class?

many thanks
