Max positions in terminal

 
We have an EA that can open a trade or several trades every pipette or 5th decimal pip. Running this on a single pair can open hundreds of trades in a few minutes. If we load this on multiple pairs it just multiplies. I'm wondering if anyone has experienced limits with number of open trades or seen MT4 slow down after a number of positions opened.

  1. Each broker has their own limits. IBFX max open trades (all pairs) is 1000. Another broker was 100.
  2. More orders, more processing. depends on what you're doing each tick.
