When I asked how much time between open/close would be considered as the prohibited "tick scalping" they replied something around 5 sec. When I said ok I will use > 5 sec in my trades there was silence in the audience.(crickets)
Then, I had to ask what is the exact time limit between open/close, they said this would scare off traders so they will not introduce any time limits, just don't base your strategy on few seconds trades, that is all I could get from them.
It's ok, their house..
