Bounds Array error

[superg3]

Hello,

I converted my indicator to an strategy, not drawings or plots, just calculations. It is based on Volume.
I'm getting the error OnBarUpdate method on bar 0: Index was outside the bounds of the array. The error is caused by the line "Value[0] = Instrument.MasterInstrument.InstrumentType == InstrumentType.CryptoCurrency ? Core.Globals.ToCryptocurrencyVolume((long)Volume[0]) : Volume[0];" but if I remove it the strategy does not do the calculations in the logic.

Please, could you help me?

Regards,

Hello superg3,

Thanks for your post.

You have two index references on that line, Value[0] and Volume[0]. I suggest printing those values on separate lines to see which is the bad index reference.

Print("Values[0]: " + Value[0]);
Print("Volume[0]: " + Volume[0]);

If Value[0] is a bad reference you likely did not call AddPlot in the script.

Please let me know if we can be of further assistance.

Hi Jim,

the output is:

Values[0]: 15
Volume[0]: 15

excuse me but I do not understand why would I call AddPlot, as I said in my first post in the strategy there is no drawings or plots, there is calculation logic only.

Hello superg3,

Please note that our morning shifts can be busy with new inquiries and it may take a few moments to return to an open inquiry. Thanks for your understanding and patience.

AddPlot is needed to make Values[][] or Value[] references. I have attached a video demonstration below.

You can set PlotBrushes to Brushes.Transparent to make plots invisible. You can also create the Plot with a transparent Brush so it is invisible.

Let me know if you have any questions.

Hello Jim,

first excuse me, I'm in Europe and I forgot the time difference.

In the other side, thank you for your clear explanation. Now my strategy is starting to work.

Kind regards,
