VWAP adapt

[carlosgutierrez]

Wanted to make this indicator but not getting anything in the chart.

Basis are the following:

input name	input description
VWAP period type	VWAP period type
Multiplier	Std Dev multiplier
Extend VWAP	Extend VWAP previous period
Extend stddev #1	Extend standard deviation number 1
Extend stddev #2	Extend standard deviation number 2
Extend stddev #3	Extend standard deviation number 3
Extend stddev #4	Extend standard deviation number 4
Set all colors	Set colors automatically
Based on input only	Computation based on input only (no volume)

Hello carlosgutierrez,

The code you posted is not doing anything so you shouldn't see anything in the chart. That only has some variables defined however i see something used which is not valid which is AddInput. If you used a third party tool to generate code for you, for example a tool like chatgpt keep in mind most external tools cannot correctly generate NinjaScript code.

If you are trying to make a new indicator I would suggest to create a new indicator using the NinjaScript editor and use the wizard to set up the plots. Then see the following help guide section that goes over Plotting

https://ninjatrader.com/support/helpGuides/nt8/addplot.htm?zoom_highlightsub=addplot

To set a plot you need to do that in OnBarUpdate:

https://ninjatrader.com/support/helpGuides/nt8/onbarupdate.htm?zoom_highlightsub=OnbarUpdate

Once you know what calculation you want to do you would write that logic in the OnBarUpdate override and set a value to the plot.
