Can someone please help me with this code?

[omermirza]

private Series<double> bulge;
private Series<double> bandwidth;

bandwidth[0] = ((Bollinger(Deviation,Period).Upper[0] - Bollinger(Deviation,Period).Lower[0])/SMA(20)[0])*100;
bulge[0] = MAX(bandwidth, 20)[0];
Plot0[0] = (bandwidth[0]/bulge[0])*100;

Unfortunately, it does not plot anything....

Hi, thanks for writing in. Do you see any errors in the Log tab of the Control Center? Please also use the Print() method to print out data from your script for debugging. This is helpful because you can see each element of your calculations in the output window:

omermirza Some things to try in addition to those suggested by NinjaTrader_ChrisL :

• Check any divisor (the thing that you are dividing by) to ensure it is not zero -- if zero, it may generate an error
• Check all other values to see if they are zero -- zero values for the final plot value will not plot
• Consider using try-catch to ensure any "unforeseen" errors are caught and made known to you

Thanks.

Hello omermirza,

There may be some confusion. A private Series<double> is not a plot.

Plots are added with AddPlot() and the values are set in the Values collection.

Setting values in a custom series is there for you to retrieve in the code, but this is not going to plot on the chart..

Below is a link to a forum post about adding plots.
