Help to convert from double to int

[safetrading]

I trying to build an indicator using Bollinger Bands with a variable period. The data I'm using for the variable period starts out as a double, and as you know, the period parameter of the Bollinger function will only accept an int (integer).

Does anybody know how I can convert my double variable (data) to an int variable to be used in the following;

Bollinger(1,data).Lower

Any help would be greatly appreciated.

Try

Bollinger(1,[B](int)[/B]data).Lower

Try

Bollinger(1,[B](int)[/B]data).Lower

Thanks, I hope I can trouble once more. That worked great, but I still have a problem executing the code. It doesn't give an error, but it will not draw my indicator.

The problem now is my two variables, PastHigh and PastLow. If I substitute numbers for them, it will draw the indicator, but when I try to use the variables, it draws nothing?

if(CurrentBar<63) return;

double PastHigh = HighestBar(SMA(63),24);
double PastLow = LowestBar(SMA(63),24);
double diff = Instrument.MasterInstrument.Round2TickSize(PastHig h - PastLow)/0.25;
double data = 34 - (diff * 1.5);
DrawRegion("No Trade Zone", CurrentBar, 0, Bollinger(2, (int)data).Lower, Bollinger(2, (int)data).Upper, Color.Transparent, Color.HotPink, 2);

Any thoughts?

Safetrading, have you printed out the values to see what is actually going on? To verify what you think should be happening, you can do something like this:

calcs using Integers should be double, but not

having trouble with int and doubles

tickPB is an int
delta is a double

delta = tickPB / 10; Print("delta "+delta.ToString());

when tickPB=10, then delta is 1
but when tickPB=9, delta is 0, should be 0.9

what am i missing? tia

[oops!]

delta =(double) tickPB / 10;

or

delta = tickPB / 10.0;
