I'm not sure if you have some kind of cognitive impairment, that you still didn't get the point after I explained it 5 times already, so I'll explain it yet again as simply as possible:

If you buy a co-located rack space you are using a PRIVILEGED CONNECTION to the market that and taking advantage of that using some algorithm: That's High Frequency Trading.

The all point of TFA and the comments was the OPPOSITE: To be in a NON PRIVILEGED position (as in, the same access time to market transactions as the median of the access time to market of EVERYONE ELSE) and to use machine learning to predict market moves in a long enough term so that the market access time was irrelevant.

Do you understand the complete difference between the two scenarios now?
