Hi WinstonTJ,
Do you mind putting your own explanation about what HFT really is.
First of all ZH should be banished from the internet and never considered a valid source for anything outside humor.
In response to 777's post: I'm ruining my own thread? By posting evidence from third parties that the HFT community are criminals?
The whole purpose of HFT is to frontrun EVERYONE ALL THE TIME. Is that simple enough for ya?
You are a pitiful apologist , fooling no one.
What about arbitrage? Market making? Neither Arbitrage nor Market Making front runs anything. The thing that I find ironic is most people on ET hate on HFT (when they don't even understand what it is) while your retail broker internalizes order flow and royally F's you over on every fill.
There are several tiers in the HFT game and most would say what I do is HFT however the ONLY reason why I automate is because I can't manually trade all the strategies at once (one at a time no problem). People like 777 are trolls and have no purpose here. The HFT debate is over, everyone knows it exists, everyone understands the barrier to entry and everyone knows that computers are here to stay. That said - has anyone looked at the DECLINE in retail order flow to the exchanges since internalization began? HFT pulls money out of the market just like any other strategy does - but at least its within the direct access pool where people know that they are swimming with big fish. Even more funny than all of the above is that with direct access AND HFT you are still better off than getting F'd over by internalization.
777's general statements and copy/pastes are wrong. He/she/it is an ignorant poster lacking the education to understand even the most basic concepts. The purpose of HFT is not to frontrun anyone. Flash trading is banned so drop it. Sub-penny trading is price improvement (your fills are better) and is arbitrage on spreads - if you don't like it change your order or move to a broker where you can submit better orders. Low latency is a higher barrier to entry and thats it.
To answer your question directly, IMO HFT is exactly that - high frequency. Lots of round trips. If you could trade the strategy manually in one stock but not in 50 stocks then its not HFT. Just because a computer buys and sells for you is not HFT. Even news trades that compete in the sub 100ms arena is not HFT since you could compete with a hotkey and a stop.
