Thought this might be useful: High end hosting for TT. It can bring latency down to ~150 us. The rough costs are as follows (hosting): Hosting in CME DC3 - 1U: $XXXX/monthly $XXXX/install fee one time Hosting in NY4 (CFE) - 1U: : $XXXXmonthly $XXXX/install fee one time XTrader Pro $1500 + Tax This is from a vendor recommended by garachen. I've spoken with them and it is something that I'm interested in assuming things go well with trading. I've removed their prices but they aren't horrible for this kind of hosting. And if anybody is interested, I've found an HFT consultant that offers a 10us tick to trade solution. Last of all there is AMP. "Free" or soft dollared TT. TT has charting and analytics so it will definitely help in finding spreads.

It is a thorough introduction incorporating trade craft, strategy and product knowledge. While it won't make you profitable, it will at least orient you to the terrain.
