adaptive stops: does the stop get wider exactly when i deserve it tighter?

So I read the volatility stop writeup in the strategy library over the weekend, the one that scales the exit distance to how much the instrument has been moving instead of slapping the same fixed percent on everything. And honestly it explains about three years of my worst habits back to me. I've been running one stop percentage across a watchlist that has both sleepy names and things that move like they owe someone money, and then acting surprised when the same rule kept getting knocked out of one and never triggered on the other until it was way past caring. Where I get stuck is the bit that makes me nervous. If volatility is high, the stop gets wider. But high volatility is usually exactly the moment I have no business holding a position at all. So the rule loosens the leash right when I'm least likely to behave. Is that a real problem or is that just me projecting my personal failings onto an if-statement. Second thing: the asymmetry, target further out than the stop. That means I'm wrong more often than I'm right and it has to pay off on the winners. I have historically been very good at the first half of that sentence. And the lookback for measuring the volatility — if I shorten it, the stop starts reacting to whatever happened in the last few candles, which feels like it could feed on itself. Widen after a spike, get filled further away, spike again. Has anyone here actually run something like this on a mixed watchlist long enough to say whether the lookback length matters more than the multipliers? I don't want to find out the expensive way for the fourth time.

The wider-stop-in-chop thing worried me too until an old desk guy pointed out the stop isn't the position sizer. If volatility doubles and your stop distance doubles but your share count stays the same, of course it feels reckless — you're risking twice the money. Scale the size down as the distance goes up and the objection mostly disappears. That's the part people skip because it's arithmetic and nobody likes arithmetic. Stay humble.

As someone who holds things for days, watching you lot argue about lookback windows measured in minutes is my favourite spectator sport. But the asymmetry point is the same at any timeframe, so you're not wrong to poke at it.

Did the writeup say whether volatility is measured on the whole session or only while you're in the trade?

Perps taught me this the hard way, a flat percent stop on something that swings and something that barely moves is two completely different bets wearing the same costume. On the feedback loop worry — it's real but it's slower than you think, a short lookback drifts up after a spike and then decays back, it doesn't spiral. What actually got me was the hold time cap doing more of the work than the stop, half my exits were just the clock.
