Being a new trader myself, I was highly interested in how HFT might affect me, but like many of you are mentioning, I'm not really concerning myself with it too much and simply watching the price action with three time periods. Horizontally I trade the 1 min, for the larger point moves I reference a 4 min, but one of the cool things I like to watch is a 100 tick. I call it my peek inside and you can see a lot of info from it. You can actually see the big lot sizes of either bigger pro amateurs or multiple sequential 100+ lots coming in. Every once in a while, you'll see a 1000+ shoot in on the 50 or 100 tick time frame. Yet another way to get more insight - at least on my personal strategy.
