creating two bands envolving the price

[julen]

Hi, I'm trying to program an indicator that plots on the chart, two bands and i'm having some problems, do you see whats going wrong in this code?

protectedoverridevoid OnBarUpdate()
{
double Value0 = (Low[0]*(1-2*((((High[0]-Low[0])/((High[0]+Low[0])/2))*1000)*1/1000)));
double Value1 = (Low[0]*(1+2*((((High[0]-Low[0])/((High[0]+Low[0])/2))*1000)*1/1000)));
double Lowerband = SMA(Value0,20)[0];
double Higherband = SMA(Value1,20)[0];
Bandainferior.Set(Lowerband);
Bandasuperior.Set(Higherband);
}

when I try to compile it returns this code errors: CS 1502, NT1503.

Thanks.

Hello,

Within the SMA() method your Value0 and Value1 need to be dataseries. Here is a link that will help you with SMA():

high-low price bands

How would I set up a set of bands that give over the period X ,the moving average of a price high and a price low.

say a 4 ma of one minute bar highs,and a 4 ma of one minute lows,set up over price chart as lines?

You could simply add two EMA's to your chart, one with the 'Price type' input set to 'High', the other with the input set to 'Low'. This should create the channel you need.
