the 3am clarity thing from that sleep-safe crypto writeup

so i read the strategy library piece about running crypto unattended with three separate ways out and honestly the part that stuck with me wasn't the code, it was the line about writing the exits as separate branches so each one is obvious when you read it half asleep. i do most of my sizing between 1am and 5am my time and i have absolutely misread my own conditions before because i squashed everything into one long if. so, point taken, i already went and split mine up. where i'm less sure is the time exit. it uses HoldTime >= 2400, so 40 minutes, and it sits as the last branch after the profit and loss ones. my question is what that number is actually supposed to represent. is it "this trade had its chance and didn't do anything", or is it more like a hard ceiling on how long i'm willing to be exposed with nobody watching? because those two would give me pretty different numbers. if it's the first, 40 min feels reasonable for a fast momentum entry. if it's the second i'd almost want it shorter, since the whole point for me is that i'm asleep and the thing that scares me isn't a slow flat trade, it's being in something while it's moving and me not being there. other bit i'm chewing on: the note that ChangeAngle scales with the window, so the same degrees over 600s demands a way bigger move in the change rate than over 60s. that makes total sense written down. but it means if i widen the window to get fewer, calmer entries overnight i also have to drop the angle, and now i'm changing two things at once and i can't tell which one did what. does anyone do this in a disciplined way? like fix the window, sweep the angle, then move the window one step and sweep again? or is that overkill for something this simple. also curious if anyone runs the loss branch tighter than the profit branch on purpose. the writeup has +2.0 and -1.5 which is already asymmetric in the sensible direction but i wonder how people pick that gap for unattended stuff specifically.
