Looks like this indi is for M1 timeframe only.
It's using M1,M5,H1;D1 data and so you have to use the indi on the lowest TF

From my point of view this indicator is not out of sync, it is simply misconceived.

If you plot something on a M1 chart each horizontal step, each candle, represents one minute. If you want now to superimpose other data from other timeframes you have to respect this constraint. For instance a single H1 bollinger band value represent 60 different M1 bars and consequently (since your're plotting on a M1 chart) for each M1 candle you have to plot the same H1 value and not 60 different H1 values like your code does.

I'm not in the mood to fix it for you, but hope it helps others for the fix.

I think that's not the problem.
The shift is an integer and is only increased if bar/period is a multiple of the period of the higher timeframe.
So i/Period_H1 will have the same value (=0) for bars 0-59 and bar 60 will shift 1 hour back

Well, you're numerically right, but consider the fact that when you read a H1 BB value you have to repeat it for the right 60 bars in that hour and not just the first 60 bars in the graph.

Its a time sync problem, for instance: if you're on the first minute of a new hour you cannot simply set the first 60 bars of the H1 buffer to the new H1 BB value. You have to set only the first bar of the H1 buffer to the new H1 BB value and then the next 60 bars to the previous H1 BB value.

Thats the problem I suppose.

I see your point and you're right
I'd changed the indi code before and calculated the individual shifts with iBarShift and couldn't see a difference on M1 chart...that's why I first thought it's ok as it is

Well done.

LOL, i couldn't comprehend your programming jargon. Sorry, I appreciate your efforts but i obviously can't use this indicator if it's only for M1.

Sorry, pal
I really don't care about the 50 bucks
But the chart you posted with an H1 timeframe and the indi you posted don't go with each other.
The indicator as posted wouldn't draw a single line on charts other than M1. To show the bands on H1 the indi must have been modified and it therefor should have been obvios that anything above M1 doesn't work.
What kind of sense does it make to show M5 data on a H1 chart?

Sorry Pal, if you have no interest than JUST LEAVE. The indicator draws lines on 4h charts and below in my MT4 platform.
