Is it possible to make multiple history lookup requests at the same time? I can issue two requests, but the second one isn't processed until after the first. I've tried with multiple socket connections and no difference.

Good morning,

You should be able to have up to 15 separate sockets pulling history simultaneously. If you continue to have issues though, send me some code to the developer email and I can see if anything jumps out at me.

Hmm.

I tried request per socket again and it works fine. Not sure what I was doing different before.

Thanks!
