Add a standard deviation to an indicator

[dvercher]

Hello

I have this indicator and I would like to add 1 standard deviation (up and down) to it.

I guess it is something like:

0+StdDev()* 1
0-StdDev()*1

But I don't know what is the exact code I have to write. Can you help me please?

Thanks

I attach the indicator

Hello dvercher,
Unfortunately we do not do custom NinjaScript coding however you can refer to the Bollinger indicator which is on similar lines.

• In Control Center menu bar goto Tools>Edit NinjaScript>Indicators...
• In the Indicators dialog select Bollinger and click Ok.

Edit the Bollinger indicator. Save it under a new name. Then replace line 48, which currently reads

double smaValue = SMA(Period)[0];

with

double smaValue = DonchianChannel(Period)[0];

Then compile via F5. Not tested.

we have a free / open-source indicator on our site that adds additional bands to the standard bollinger indicator.

here's the link:

perhaps you can compare it with your code or tweak it to your liking.
