Thank you. I can see how that code will trade on multiple instruments at once but my bot runs on each bar. It then analyses the bar data against a set of indicators and if I think there is a trade it will place the trade. I am not sure how I can get the latest bars for  AUDCAD, EURJPY and USTEC (for example), analyse each one and then determine if there is a trade?

Hi Jay,

You can use GetBars() to get the bars for any symbol you want.

Sorry one final question...to then back test the bot, do I need to still set up an instance against a single instrument but then the code underneath it will go away and get all the data it needs?

Thank you very much for your help! I am thinking that because it is c# I can code it so that instead of a for each I can run every instrument I go after in a Parallel For each, as long as I set a sensible Max Degree Of Parallelism so that I do not cause the machine it is running on to crash
