Hi,
I noticed that in Launcher/config.json
// algorithm class selector
"algorithm-type-name":
One can only specify 1 algorithm for Lean to run.
I find this discussion:
and Algorithm.CSharp/MultipleSymbolConsolidationAlgorithm.cs
My question is can the Lean engine fully take advantage the hardware multi CPU/core, and run either (multi?-)algorithm (or multi-symbols) on multiple threads (on different cpu/cores)? if yes, any instruction / example on how to do it?
Thanks.!

BTW, I'm only talking about backtest on multi-CPU/core, right now. Not live-trading (if yes, that will be even better).

LEAN uses as many cores as there are available, but is bottlenecked by the synchronization of the data. It depends largely on how much data you're synchronizing the wall-clock speed of your backtest.
