Market Analyzer filter or alerts on 0 (not n/a)

[NinjaCustomer]

I have an indicator with 2 plots... they work in tandem. In the data box it will show either 0 or n/a for either plot and each plot is the opposite of the other meaning if the first plot is 0 then the second is n/a and if the second is 0 then the first is n/a

How can I set up the market analyzer to filter or alert when a plot is 0? (but not n/a)

I'm asking because the columns I set up (I set up one column for each plot), always show 0.. both of them.. even though i know some values must be n/a

p.s. what is the code equivalent of n/a is it a null value?

Hello NinjaCustomer,

Thank you for your note.

In your indicactor, what state are you making your AddPlot call, State.Configure or State.SetDefaults?

I look forward to your reply.

AddPlot calls are in SetDefaults

Hello NinjaCustomer,

The recommended way for achieving this in NT8 would be using a custom MA column to access your indicator values / exposed states. Attached is an example which demonstrates this.

Import the attached .zip and on a Market Analyzer window, add the column AlanMAColumn.

In the NinjaScript Editor you can find AlanMAColumn under MarketAnalyzerColumns, which you can use as a guide for correctly displaying information to the MA window and which you can then reference for your alerts.

Please let us know if you need further assistance.

thanks, where can I find the documentation to create my own custom column? that's not specifically about this issue - it just sounds interesting and i'd like to read about it

Hello NinjaCustomer,

If your plots are always outputting 0 when you know it should be another value, it’s likely not set up correctly in the Market Analyzer which is why I suggest using the approach I provided.

Once you have the plots correctly displaying the value in the market analyzer window, you could write click on the MA>Alerts and define an action to go off when that column is displaying a value of 0.

I rewrote the sample I provide you so that it will display either a 1 or -1 in the MA column depending if the SMA of this bar is greater than its last bar. From here you could then set up an alert. I have provided screen shots of how you'd set up an alert for this.

The following section of our helpguide goes over setting up a market analyzer column,
