Is there a bug or change in MQL5 update? Having problem with iHighest / iLowest functions

[Anil Varma]

Another thread with the same issue in OOP class https://www.mql5.com/en/forum/467428

Now today I am trying to run an indicator where Highest values are calculated and I am getting price much lower than the Highest price.

double   price1  = iHigh(gSymbol,PERIOD_H1,iHighest(gSymbol,_Period,MODE_HIGH,28,iBarShift(gSymbol,_Period,FxSession[i][pID].Begin,false)));

I have used the indicator earlier, with the correct results.

Just trying to reconfirm, if there is new bug/change in the MQL function as it is happening at two different codes.

regards.

According to iBarShift documentation:

exact=false [in]  A return value, in case the bar with the specified time is not found. If exact=false, iBarShift returns the index of the nearest bar, the Open time of which is less than the specified time (time_open<time). If such a bar is not found (history before the specified time is not available), then the function returns -1. If exact=true, iBarShift does not search for a nearest bar but immediately returns -1.

[Vladislav Boyko]

Write down the expected values ​​from FxSession[i][pID].Begin, iBarShift, iHighest and iHigh somewhere. Print all these values ​​into a log and compare them to the expected values. This way you localize the problem.

In the meantime, this looks like a question for psychics.

Better yet, find these bars/values ​​yourself, without using built-in high-level functions

You only copied the price.. the index has changed on truncated price data after the copy

double   price1  = iHigh(gSymbol,PERIOD_H1,iHighest(gSymbol,_Period,MODE_HIGH,28,iBarShift(gSymbol,_Period,FxSession[i][pID].Begin,false)));

You find the bar index on the current timeframe, and call iHigh for H1, passing the bar index from the current timeframe

Thank you everyone for your time to reply.

@Vladislav Boyko you caught the right problem. I did change PERIOD_H1 to _Period in iHighest() but forgot to change the same in iHigh(). Seems I needed a break :)

Can you please look into another thread also, seems I must have made some silly mistake which I am not able to trace.

THANKS A LOT.

Hi @Sardion Maranatha

Is your reply relates to earlier thread at https://www.mql5.com/en/forum/467428?

If true, please elaborate what did you mean in the same thread, instead of here.

Thanks a lot
