Thanks all for your helpful comments. This is my third week trading ES. I only trade ES. I agree with most posters here, and I can attest to the fact that the way HFT impact my trading is by beating me to fill of my order. We are all looking at the same market and the way they beat non HFT traders is how fast can they get fill when they know an impending move. Usually 1-2 ticks.
Thanks again,
Sid
I don't think HFT *knows* about an impending move, they may rush in to get an early bid/offer once a price levels clears out and offer/bid the other side immediately but several ticks away from the inside market where you are located, I don't think HFT is *beating* you. They already played their game at that level several ticks ago. They have the speed to play the inside bid/ask game and also have the commission/exchange fee structure to do it. If they can get first to a bid offer and get filled very quickly, and the momentum starts to die, they can simply market out for a scratch and their costs are ridiculously cheaper than what you and I pay. So when they scratch they might lose 20 cents but when the momentum continues and they pick up a tick, they make 12.30. It's a pretty good risk reward scenario and it's only possible because of their speed and pricing structure.
For a point and click retail trader (I'm assuming this is you) dropping limit orders in a few ticks away from the current inside market, I really don't think HFT is affecting you too much, at least in how orders are getting filled.
As said previously, were I you, I would be much more concerned with your wrongly skewed risk/reward profile. maintaining a 70%+ win rate consistently is very difficult and low profits mean commissions and exchange fees really play a big role. So in your example and assuming a $4 RT on ES fees:
Winning trades (2 ticks) net you $21
Losing trades (3 ticks) cost you $41.50
so in order to BREAK EVEN you need just about 70% winners.
I'm not saying it's impossible on a short time frame to get 70% winners but I know I've tried that math and I can't make it work on my end. Finally, if you're going to do this strategy, you really need to have the lowest costs possible, if you are paying TDAmeritrade prices, forget about it. You need to be at least $4 or lower and don't let anyone fool you, with a strategy like this, a nickel or a quarter lower can make a big difference because I don't think it makes a ton of sense on a strategy like this to take 2 or 3 trades a day. This is a manual high frequency model. All of this IMO of course. Good luck.
