Does anyone know how many instruments market replay can play at the same time?
I want to do this so that my market analyzer window can pop up alerts in the alerts log.
Then I can go over those previous historical signals on each chart.
I am wondering if someone here has replayed say 100 symbols at the same time and what their experience was like for them.
There is no limit, at least with all the instruments your can download from Ninja servers.
But with all the available replay data, that's something around 250 GB of data, the connection to the replay engine can take a lot of time (more than one hour).

I've used c40 (from own recordings of live data), it runs well even at high speed, but don't get too excited as the 1 second resolution impacts the usefulness of anything you want to do with bid/ask/trade data for example, otherwise fine.
