First, great chart annotations, make it a pleasure to read, so thanks for that.
Thank you.

It's actually how I work for myself all the time (Morge inspired): each day becomes a collection of 10-20 such screenshots (after deleting the redundant ones that don't contribute much) which I archive in a handy PDF. I like annotating what I see as it happens; it keeps me focused. Disk space is cheap and it's the best way for me to later review everything I did.
Did your plan say that trend was up at the moment of your long entry? Or does the short term trend not factor into your thinking?
The prior day was the first up day in a very long time, so I didn't have a larger timeframe trend in mind. (If anything, shorting the supply line we partly see would've been interesting.)
I like starting fresh most days anyway and just trade what's in front of me. I mostly take note of the prior day's high and low, and then look at behavior at the open (9:30 Eastern) and at those levels for a while (could be hours) until something becomes obvious to me
and affordable enough. Part of my edge is in being picky. On this day we found buyers first, so I was then biased long, but we found strong sellers, which put me in neutral until one side would show a stronger hand. While waiting for that tell, I noticed that we had two level tops and bottoms, forming a wide enough range (20 points), so I bet on price continuing to range. Not my favorite setup, but since I want just 10-20 points per day it would've been fine.
Afterwards, my stop was the tell to short, and at 10:40 I had a setup, but the only safe target was prior day's low, yielding a mere 2:1 reward, so I passed. Turned out to be the only setup for the 55-point move down, but I'm happy that both this loser and my lack of entry short thereafter, albeit frustrating, followed my plan. It kept me out of plenty of trouble already so I'm not in a hurry to change it.
