How do I iBarShift in reverse?

Hi,

I want to use a For Loop to check if price breakouts after a certain time. But I want to check it forwards instead of backwards. How do I do that?

The Time1 is the Time I am using, but what should the CurrentBar be? Should it be set to 0 or what?

I want to measure from Time1 all the way to the latest bar on the chart.

for (int d=iBarShift(Symbol(),0,Time1,false);d>iBarShift(Symbol(),0,CurrentBar,false);d--)
{

}

Not quite sure what you're asking. The inverse function of iBarShift() is iTime()
i.e. iBarShift(symbol,tf,dtvalue) converts a datetime value to a bar (candle) number, while iTime(symbol,tf,bar#) converts bar# to the corresponding datetime value that is the date/time (at the start) of that bar.

iTime(symbol,tf,0) will give the start date/time of the currently forming candle (candle #0) on a chart.

If referring to the current chart, you can simplify iTime(symbol,tf,bar#) to simply Time[bar#]
bar# should be defined as int, in either case.

What I mean is that the normal way of using iBarShift is through shifting from the current bar backwards. I would like to shift from a bar forwards in time.

So the for loop has to be i-- instead of i++

The shift has to start from the biggest and then go smaller and smaller.

How should the for loop look like?

I know that the code to check between two time is like this:

for (int d=iBarShift(Symbol(),0,Time1,false) ;d>iBarShift(Symbol(),0,Time1, false);d--)
{

}

What is the code to check between Time1 and the Current Bar?

Assuming that d is going to represent the bar# on the current chart, then something like

for (int d=iBarShift(Symbol(),Period(),Time1); d>=0; d--)

should work.

Are you talking about shifting the bars to the right of the zero bar?

That is like trying to project the next bar to the right or something like that?

if so iBarShift donot work on any bar to the right of the zero, you have to create your own bar count.

No I am not.

Hanover already presented the correct solution to what I am doing.
