Right now I use the BollingerPercent in Ninjatrader. I was interested in switching to Sierra charts. I was wondering if anyone knows how to code the same BollingerPercent for Ninja into a format for Sierra charts. Any help would be appreciated.

There is already a native study called Bollinger Bands %B.

Here is some info on its inputs and the formula it uses:
Sierra Chart - Technical Studies Reference

Thanks Tom. Does the indicator look like this. Just want to make sure before switching.

It can be made to look like that. Sierra is very configurable.

The study seems to produce values ranging from slightly less than 0, to slightly greater than 1.

Give me an instrument and timeframe that you can use to compare, and I'll create a chart with the study and post a screenshot.

Thanks Tom, I really appreciate it. Looking at February CL emini with 800 tick chart candle stick.
Thank you Tom, I am new to Sierra and want to make sure I am getting the charts I need.
If you don't mind also I would like to have the Cumulative Delta on the chart using the Bid/Ask difference in continuous mode. Also on the BollingerPercent can I change the Input data based on something else like a ema or something like that.

Thanks
Hector

Here are the screenshots. The settings screen is for the %B study. You'll notice several input options including MA type.

All colors and line widths, etc are configurable. I tried to match your pic.

You should request a trial from Sierra Chart to see if you like it. It comes with data that is not realtime.

Tom ok I got it. Here is a screen shot of what i have right now. The Bollinger doesent seem to be like yours. Nor are my bar colors
are not the same. Is there something I am doing wrong.

To get the %B to look like mine (like your NT), do this:
1) On the %B study:
-set the Lower Line Threshold Value to 0.00000001
An exact zero value will produce no line.
On the Subgraphs tab:
-Set the Upper and Lower Threshold Line Styles to Solid
-Set the colors and line widths
2) Add the Line study
-Set the Chart Region to the same as the %B study
-Set the Value to 0.5
-On the Subgraphs tab, set the color and width
3) Add the Reference From Two Studies study
-Set the Chart Region to the same as the %B study
-Set the Input Study 1 to the %B study
-Set the Input Study 2 to the Line study
On the Subgraphs tab:
-Set the Study 1 Draw Style to Bar Top
-Set the Study 2 Draw Style to Bar Bottom
-Set the colors and widths
