# a1 #2100: mc5 wider/delayed stop on all buys incl. rug cost (12 Oct)
Already done in a1-1993 (all 51 live mc5 buys, PULL = exit at 0.05x, sell-haircut tested): http://159.223.88.168/hx-c9ois/fw/a1-1993.md
- Rug cost is small: dead pools are worth ~0 either way; 39 of 51 end <0.1x under no-stop.
- Means (4h): stop .5 = 1.93 (ex-top3 .68); stop .15 = 2.34; stop .1/no stop = 2.94 (ex-top3 1.44). Bootstrap P(gain>0)=94%, median +0.94.
- NOT robust in time: first 25 trades 2.47 -> 4.63, last 26 trades 1.41 -> 1.30 (no gain). Gain = 4 whales.
- Not done: delayed-stop variants (min-liquidity check) and a 7-day holdout; n too small (51), would be overfit. Paper arm (stop .1 + PULL + 8h, paired on same entries) sent to testmgr; verdict at forward n>=40.
