What do u think will happen if all traders use the same ATS systems :)?

That's correct.

Quote from Tums:

The day people agree on anything (including which ATS to use), there will be World peace.
No market is needed from that day on.
There will be no bid/ask spread.
There will be no overbought/oversold.
There will be no volatility.
There will be no market !

maybe they will start stupid threads.
