Market Data Question

[26psicivic]

Hi, I am using onmarketdata to look at bid and ask. My question is can I add other instruments and look at those bid and ask? Could someone point me in the right direction? Thanks.

Hello 26psicivic,

Thank you for your post.

Yes, when using a multi-instrument script a subscription to OnMarketData() will be created for all bars series added to the script. You could use AddDataSeries() to add a series for whichever other instruments you would like to look at in your script, though it is important to understand that OnMarketData() can be very CPU intensive and should only be used when needed. You could filter through the different instruments in the OnMarketData() updates with marketDataUpdate.Instrument, as this is one of the MarketDataEventArgs:
