lol I know :-) You again fall to the same trap... no retail trader is planing to front run the market on sub second time spreads (as MOST HFTs do). Not because it can't be done technically (from my +15 years of IT background I assure you it can be done) but because you need lots of capital to make it worth while... something like $100,000,000 to get started lol. Again... it's not about sub second HFT execution. I'll share with you this (To make it simple assume a perfect world): I'm located 80ms from Chicago, or 160ms round trip. if in the moment of order entry, all last 100 trades got to my end as 80ms old, that means I took a trade based on the most "fresh" information I could have at my end, right? What if a "safety study" finds that the data I have at my end is older than that? lets say 100ms old? it means something adds latency... Maybe my ISP? my data provider? a router along the way? a problem in the exchange? What if I find that it's not even 100ms stable, but with every new trade the data gets older? [100ms>105ms>107ms>112ms>130ms etc etc]? At this point my study will decide to either scratch the order or maybe compensate the entry by few ticks for safety... all based on rules. Does that have anything to do with HFT **execution**? Nope. |
