the forced flat line — where does it sit in your exit block?

Read the time-window skeleton in the strategy library over the weekend and it's already changed how I lay out my exits, so thank you to whoever wrote it. But I want to poke at one thing before I commit it to anything live. The exit block puts the flatten-before-close check first and the profit/loss/hold-time checks in the elif underneath. I understand why — time beats everything, no argument. What I'm chewing on is the mirror problem on the entry side. My window opens at a fixed time, and anything I skip before that is skipped forever, which is fine, that's the point. But the closing edge feels different to me. If I'm four minutes from the end of my entry window and a signal fires, I'm taking a position that only has a few minutes of runway before the flatten rule grabs it. That's not really the same trade as one taken mid-window. So the checklist question: does anyone add a second, earlier cutoff for *new* entries, separate from the hard flat? Something like entries stop at 14:30 but the flatten doesn't hit until 15:45, so anything opened late still gets a fair hold. Or is that just me inventing a parameter to fiddle with? Second thing, less interesting but it nags at me: half days and early closes. A fixed 15:45 flatten is a lovely rule right up until the session doesn't end when you assumed it does. How are people handling that, a calendar check, a wider margin, or do you just not trade those days at all? I'd rather decide it now than discover it by accident, which is exactly the sin the piece warns about with overnight holds.
