Quote from dandxg:
There are a few markets that algos have dominated just yet.
I'm not sure what you mean... algo's have dominated most or few markets?
And, about algos, here is my researched but inexperienced 2 cents... most of what I read about "pure HFT" is done on equity exchanges where some firms can post and cancel "flash" orders before other firms get the chance to hit them (I saw a video on youtube that described it pretty well). I will concentrate solely on futures, were as far as I can tell, there isn't the two-tier system like there is on stock exchanges. Also there are messaging limits on futures exchanges which I think help curb it down.
On futures, I know that autospreaders (especially in financial futures) play a big part, and on futures where it's FIFO I can see how fastest spreader / latency makes a big difference... but since you're probably talking micro-seconds for a computer to do it's thing, and the average humans reaction time is like 200 milli-seconds, I wont spend any time sweating over it.
Another thing about futures is that all trades are reported on the time and sales... so whatever an algo does it reported. I think most algos are designed to execute big customer orders without anybody ever noticing, i don;t think they are designed to snoop out where someone might be caught... i think (hope) that is a skill that takes a human to perform, and that I can learn it!
