I want to modify bollinger indicator. Are these instructions valid?

[mangustas]

Hello,
I want to do basically the same thing as it is written in this thread. https://ninjatrader.com/support/foru...-based-on-vwma
Creating a bollinger band using VWMA, as opposed to SMA, basically a rolling VWAP and std dev bands.

I've checked, that new NT8 Bollinger script has much more code lines. Are there aditional modifications that need to be done? Also, would prefer to have 2 indicators, one original bollinger and the other modified. Is it possible to get help there?

Hello mangustas,

Welcome to the NinjaTrader forums!

The modification would be different.
In the copy indicator, on line 57 change:
sma = SMA(Period);
to
sma = VWMA(Period);

You can also add other indicator calls if you would like.


Below I am providing a link to a forum post with helpful information about getting started with NinjaScript and C#.

Hello Chelsea,

Thank you for replying so fast!

Now the trouble is that I dont have access to ninjascript editor. I've tried changing the line mentioned via notepad++, but got "You have Custom Ninjascript Files on your PC that have programming errors. These Errors must be resolved before you can import a Ninjascript Archive File new indicator"

Is there a way to I could modify/copy and modify without ninjascript?

Hello mangustas,

The NinjaScript Editor can be found at the bottom of the New menu when using a Simulation only, Lease, or Lifetime live licenses but cannot be used with the Free live license. Contact platformsupport [at] ninjatrader [dot] if you would like to obtain the Simulation Only license.

You will need to make the copy of the script in the NinjaScript Editor and then modify the copy.
