Indicator dissapears after clicking OK

[ttodua]

I have an indi, after adding into the list


and clicking APPLY, it plots on chart, but after clicking OK (or CLOSE) button, everything (lines) hide, and in databox, every values aside labels are empty...
what happens?
this started to happen, after I tried to manually add 2 plot lines in existing ready-made indicator.

(attached the script)

if I comment he 673 & 674 lines:

//PreSessionHigh2x.Set.....
//PreSessionLow2x.Set....

then problem goes away.

Hello selnomeria,

I've tested your script but I am not able to reproduce the behavior.

How exactly did you declare and sync your extra Plots? Show all the lines that you added to the file in order to enable your extra plots. We cannot just Set a plot value without first setting up the Plot object properly.

thanks for excellent support.

it's strange , why it gives me problems... maybe beacause I use imported 1 min-sample data for chart?

here is the comparison of the initial file and modified file:

error in log shows me:


I find, that if i remove the customly overriden method "PLOT" from this indicator, then it seems to work for me (but without that method, the custmization is lost).

Hello selnomeria,

As a heads up, overriding the Plot() method is not supported or documented for NinjaTrader 7 nor are custom TypeConverters. This means the unsupported code the NinjaTrader staff is not able to assist with.

However, this type of indexing error just needs to be debugged and can arise anywhere in the script indexes are being called.

I recommend you add prints to the script throughout the Plot override to find the exact line that is causing the indexing error.

From a glance, there appear to be 14 plots (indexes 0 through 13) and anywhere there is a hard-coded reference these all appear to be valid. I would be suspicious of loops. Prints will be very helpful here to see what indexes are being accessed in the loop.

Below is a simple demo of using prints to understand behavior.

thanks for hint.
I've started to debug and found out that the index of Brushes was not enough for Plots...
thanks! solved!
