Loading Instruments via Add() is slow

[karlmac]

Hi,

This is my first time posting in this forum so please bear with me. Also, I am a newbie at programming indicators in NinjaScript. In my Initialize() method I have the following lines of code:

// Add symbols			
			Add("$EURUSD", PeriodType.Minute, timeFrameInMinutes); // index 1
			Add("$GBPUSD", PeriodType.Minute, timeFrameInMinutes); // index 2
			Add("$USDCHF", PeriodType.Minute, timeFrameInMinutes); // index 3
			Add("$USDJPY", PeriodType.Minute, timeFrameInMinutes); // index 4
			Add("$USDCAD", PeriodType.Minute, timeFrameInMinutes); // index 5
			Add("$AUDUSD", PeriodType.Minute, timeFrameInMinutes); // index 6
			Add("$NZDUSD", PeriodType.Minute, timeFrameInMinutes); // index 7

The indicator is now running correctly however I am bothered by the fact that going through these lines takes NinjaTrader a long time to load. Is this normal for an indicator loading this much instruments via Add? Is there any alternative way to do this faster/more efficiently?

Thanks!

Welcome to our forums Karl - yes depending on how many days you load the primary series on your charts for this could take some loading time. Which data provider are you working with?

Thanks for replying Bertrand. I'm using Kinetick as my data provider. So one of the things that I can do to hasten load times is to decrease the number of days loaded? Can this be done in the indicator programmatically? Thanks!

You're welcome, ok. Correct, the less data it had to load overall, the quicker performance should be. It really depends how much you need for your analysis. Programmatically setting this would not be an option unfortunately, it would depend on what you set to use for primary series.
