HFT market makers aren&#x27;t doing complex quantative analysis in microseconds it takes to do trades, and latency arb isn&#x27;t &quot;an immediate arb in another product&#x2F;exchange&quot;, that&#x27;s just normal arb.  Quants are used for longer term stuff, not microsecond level stuff.  HTF&#x27;s are doing order book stuff and flipping the spread, nothing hugely complex, just fast.
