Quote from Matcha:
So, "Oh, Sifu..."
Do you also play premarket?
I do (or should say "used to"). But from my recent experiences, it is only a 50-50 game. When it goes against me, it goes really fast (thin volume) and hard. A couple weeks ago I have decided not to pursue it. I don't like the odds. But I do watch pre-market activities intensely. They clue me in to how to trade the first 1-2 minutes.
Gaps are very hard to master. Because you may be right 80% of the time. But when you are wrong that 20% of the time, the market kills you. Fast.
Someone on ET recently asked about how to trade the gap. I wish there is a simple answer. There are so many things to consider. e.g. The recent 3-5 sessions' activities. How big is the gap? Did the gap break above recent resistance or below support? How's the stock gapping compared to the S&P? Gapping more? Or gapping less? How did the pre-market price go? A gradually buy-up/sell-down? Or gapping big (from last night) right from 08:00 am EST? How did price run into the closing in prior session? How is the price gapping compared to today's pivot levels (PP, S1, R1, etc.). You see, there are many things to consider.
There is a self-proclaimed "The Gap Guy" Scott Andrews who had written a book on trading the gaps. I had bought and read his book. (Which I regret.
Anyway, ranted too far. I will rant some more in a new chapter of my new trading book "Trading The Gap".


Any given day they may differ in their movements by a few percentage points. But usually negligible.
