That’s a big problem. Not sure if newer NT is multi-threaded, but either way, the inability to stack multiple strategies at tick level is not good.
I don’t operate beyond trade/tick level, but I’ve read about MC users trying to manage order book dynamics. Personally I don’t think it’s viable for that purpose. I do however believe it does allow for storage of IQFeed order book bid/ask data.
What do you mean by "the inability to stack multiple strategies at tick level is not good." I have many charts open with strategies running real time with no issues. Every incoming tick is analyzed by the code.
