GetInstrument(...) throws 50 errors

[defa0009]

Any ideas why I'm getting 50 error dialogs on my screen when calling...

if(Instrument.GetInstrument(symbol) != null)
AddDataSeries(symbol, Data.BarsPeriodType.Minute, 1);

Hello defa0009,

Thank you for your post.

It looks like you are passing a variable to AddDataSeries(). Please note that AddDataSeries() should not be used dynamically and is not supported to be used in this way:

"Arguments supplied to AddDataSeries() should be hardcoded and NOT dependent on run-time variables which cannot be reliably obtained during State.Configure (e.g., Instrument, Bars, or user input). Attempting to add a data series dynamically is NOT guaranteed and therefore should be avoided."

If you hardcode the AddDataSeries() call, are you still getting this error?

Not ideal but I'll trying hard coding.

Do I need to call AddDataSeries("EURUSD") if I'm going the unmanaged route... which would be at the account level? All Instruments should already be available at the account level correct? Can I just do...

Instrument instrument = Instrument.GetInstrument("EURUSD");

If you are using the Unmanaged Approach in a strategy script (i.e. using SubmitOrderUnmanaged()) then you still need to use AddDataSeries() to actually pull in the data.

GetInstrument is returning the instrument object but isn't actually pulling in any data for the strategy to calculate.

I'm using the addon approach CreateOrder(...)

Hello,

In that case, yes, you could simply use Instrument to pass into CreateOrder() as the instrument you're submitting the order to.

Ok thanks...that made it way more simple and all those errors went away.
