How to create a new indicator by modifying current one

[HiddenPhilosopher]

Hi,

I'd like to do a simple modification of a current indicator. In the system, Bollinger Band uses SMA of close price for calculation. Instead, I want to change close price to "(high + low + close) / 3". How can I do this simple change? I don't know about coding.

Thank you!

Hello HiddenPhilosopher,

Welcome to the NinjaTrader forums!

The Typical may already be an existing data type that you can select for the SMA Input Series in the Price Type drop-down.

If the Typical price type is not what you are wanting, this would require coding as you are wanting a custom calculation with custom math.

The custom calculations for each bar can be saved to a custom Series<double>, and this can the input series supplied to the SMA indicator.
