I have the following question. There is a block in init(), which hangs the terminal (that's what I want to transfer to dll). Naturally, the log cannot be viewed - the terminal is only closed by Ctrl+Alt+Delete. Unprinting in order to trace (and to measure transit time of loops coming into block) doesn't help - printer doesn't write anything, logging is not even created. I try to use FileOpen/FileWrite with the same purpose - file is just created (0 Kb), and silence. I put FileWrite after FileOpen, on the next line - no effect. Which way should I dig?

Try to use this. If it doesn't help, to search for errors, you can temporarily put mentioned initialization block into start for one-time start via flag and try to "pull" logs from it.

Look, there is no hidden in the attributes?


It's not hidden.

Neither one-time startup in start nor ininit works - neither Print nor FileWrite. I'm attaching this piece of code (I don't see another way out), I'm not going to post it here, because it's too long. I have removed all buffer declarations and described all calls of built-in technical indicators there. I've already thought about memory overflow with arrays, I've calculated that the biggest array plus all other arrays is fifty and a half meters. Well, if it doesn't print even on the very first line, when entering the block... - that's what's bothering me. Attached version is true with FileWrite.

The style of the code does not dispose of it. No spaces, brackets at different levels, several operations in a row, no comments... Nightmare! :-))

Do you understand it yourself?

 
Help solve a problem with MT4. When calling up a custom indicator, its input parameters and colours in the window are not displayed (blinks quickly and disappears). How to fix it? Reinstalled MT4, didn't help.

I agree with Vadim - the code is hard to read. Try to decompose this code into functional blocks, in each block print or write to file. And run it in a structure that "slows down" the code execution, for example, like this:

void SteppingThrough()
{
    int  li_Time = TimeLocal(), li_N = 0;
    bool lb_work = true, lb_break = false;
    while (IsStopped() == false)
    {
        if (lb_work)
        {
            switch (li_N)
            {
                case 0:
                    //---- Block 1
                    lb_work = false;
                    li_N++;
                    break;
                case 1:
                    //---- Block 2
                    lb_work = false;
                    li_N++;
                    break;
                case N:
                    //---- Block N
                    lb_break = true;
                    li_N++;
                    break;
            }
            if (lb_break) break;
        }
        if (TimeLocal() > li_Time) {li_Time = TimeLocal(); lb_work = true;}
    }
}

Delay the execution of the next block by 1 sec. - The terminal should have enough time to print the log.

 
 

There are 2 very similar functions in Kim's "last position close flag by STOP" and the other by TAKE.

here is the code

As you can see they are very similar.

But for some reason, only closing by STOP works for me.

SL=  isCloseLastPosByStop("", -1, -1);
TP=  isCloseLastPosByTake("", -1, -1);

Print(SL,"_",TP);

It works, but my Expert Advisor does not print UNIT, but keeps printing NULL.

But the close at STOP prints correctly: if stop = 1, if not stop =0....

help me out please....

I open position manually, put short TAKE. it works - but EA does not print UNIT, but continues to print NULL.

But the close at STOP prints correctly: if stop = 1, if not stop =0....

help me understand this please....


Look carefully at what price the stop order had in the open position and at what price it exactly closed. Igor's function compares these exact prices but does not take slippage into account.
