Funny, snack, your story is similar to mine. I closed my engineering firm about 12 years ago due to economics and had a small kid to raise so I chose something I could do from home as a side job. Well now it's my only job, the wife is gone but the kid is still here and it still works great. Plus, as you stated, most days we're out of here before 9 (AZ/Pacific time) and can basically do anything the rest of the day or try to pick up table scraps in the last hour.
Being of a technical background all I could think of back then was "Why are they buying? The PE ratios are at 200:1, half the companies don't even report positive earnings yet stocks are at 52-week highs and yet we go up." No logic in this gig - none! Then I decided to ignore logic and the why's and concentrate on price and the how's and how to capitalize on it and here we are. I discovered charts and TA and love it.
Your trading sounds a lot like mine, plus let me add there's almost always a reversal at 6:50am - be aware of that as well. I also stay away from news at 7 etc. Sometimes they buy good, sell bad, or buy bad and sell good. You have a fiddler's chance of being right with these cats comes to news reactions LOL.
Good trading to you.
