Or is there some easier way to get this value?

   zz=iCustom(NULL,0,"ZigZag",InpDepth,InpDeviation,InpBackstep,0,InpBackstep);
   if(zz!=EMPTY_VALUE)
     {prev_zz=curr_zz; curr_zz=zz;}

Attention question: is it a valid approach to loop through the values of the indicator buffer, starting with a zero shift deep down, calling the iCustom function at each iteration, until the resulting value is different from EMPTY_VALUE?

yes

How should I write the code so that it would perform the following actions?

tick-check for open sell order within +/- (up/down) range of 10 pips from the price, if no open sell order

If i'm not sure i've got an open Sell order, then i should open a Sell order. The book is similar to C++.

I'm sorry if these questions are too wise.

Go through opened deals and compare the opening price - whether it falls within the Ask+10 to Ask-10 range, if it does, it means you have an open deal.

"As a last resort, open a Codebase and see how to do it)

Thank you. It didn't have any effect for some reason.
