Hi all. I thought I had once come across a way to test latency to Rithmic thru either RTrader or NT7 but for the life of me I can't remember how I did that. There was an option within the app (not using ping or tracert). Does this ring a bell to anyone?

Ha I found what I was looking for.

There's a ping test under Window -> Preferences -> Performance in RTrader Pro.
