Instrument not found

[kltdco]

Hi, I'm trying to add several instruments in the Initialize() method by calling Add(). What I'm observing is that for some of them the following message appears in the log:
9/21/2011 6:25:35 PM Strategy The strategy 'Ema13/c8e4129f7b844cdcbbcbebd207a920d3' has called the Add() method with an invalid instrument. Either 'NUVA' does not exist in the Instrument Manager or the specified exchange has not been configured.

If I now go and open the chart with this same instrument, then again try to run the strategy - the error for this particular instrument disappears. So it looks like it can't load some instruments via Add(), but the same instruments are correctly resolved in the chart. Can you help me to fix it? If it matters in any way - I'm using an MB Trading account. Thanks.

Hello kltdco,

If you create a chart with a previously unknown equity, then it automatically adds this instrument "on the fly" to the instrument manager. It won't do this for unknown instruments through the Add() command though.

So, I didn't get it... What should I do for me to be able to add this instrument to the strategy programmatically?

Is NUVA in your instrument manager?

Looks like not... If it was there I guess I wouldn't have had a problem. The question is how to add it programmatically so that I could add a series for my strategy input.

Like NT_ryan mentioned, Add won't do it. I don't think anything can.
