icustom and copybuffer problem

New comment
 

Hi every one.

pls help me im tired of this.

this is a simple code that only use icustome and copybuffer to get value of rsi

the problem is:

when Chart Time frame is different from TF you set on icustom it returns -1;

i test it with many indicators its the same

i set PERIOD_D1 to icustom. CopyBuffer only return value if Chart time frame is D1. else it returns -1;

What does it means? how it possible?

PLEASE HELP ME.

Perhaps you should read the manual, especially the examples.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick (after the indicator has updated its buffers,) you use the handle, shift and count to get the data.

tnx for answer.

but how about offline chart after market close?

ontick dont work on closed market and i need to load data on specific TF while chart TF is different.

i.e im in H1 chart and i need RSI D1 value.

 

It is the same problem i have

I can't find one method (if exists) to get a buffer of one indicator into other indicator, if the first one is in different PERIOD.

In fact, in the second entry OnCalculate, when prev_calculated !=0, CopyBuffer returns the number of Bars copied in PERIOD_D1, but all data copied in Buffer are erroneus.

It'is not a problem using a EA, 

Somebody now how to do? or if its possible to copy in a indicator data of other indicator in different PERIOD?

Thanks
