In the morning I am hitting bids/offers using 50/100s to hide what I am doing, certainly not going to be doing limit orders and add contracts to what is there. I am reading the Dome, I can tell when price is going to move up/down 2-3 ticks most the time in first 45 minutes so when I see it going to up a tick am hitting all the asks. Watch the DOME for three years, glasses get thicker but you learn price movement.
99% of the time I place exit orders before I get in, my exits are actually reversal orders as most of the time the market should reverse in that area, but I have to continue to hit bids/asks to hide what I am doing. Half of my trades I am reversing into other side, it depends on how far price has gone away from the middle, am just trying to play for price to get to the middle. If bigger brokerage saw what I am doing, they might do a HFT on me and make me pay for my stupidity. The markets are controlled sometimes for a handful of ticks to hit stops, I don't want to get caught up in that. Inexperienced traders are the ones getting into the market at the middle, and I am providing size they can do so, I would guess most of who I trade against are those who loss consistently. I just watch one and two minute charts all day and I can see where they will get screwed the worst and most often. There are other patterns that are based purely on emotions of inexperienced traders but most traders have names for these patterns like Head & Shoulders or flags, I have asked hundreds of inexperienced traders what they feel when they see these patterns and have drawn conclusions based on what they feel. I have just taken my style of trading to different level of learning my craft. Everyone does it differently, but I watch patterns of small differences of highs/lows, looking for "rounding" of extremes, I know at how many ticks beyond a pivot will it reverse or trend to continue, of course they are all based on the past experiences and back testing, but how my hobby from long ago makes me decent coin.
