I don’t post a Dow/YM Fuseline, but I could look at it. For SPX and SPY, the translation from ES is straightforward enough once you account for futures premium, and AI makes that conversion easy now.
NQ and especially YM are a different animals. The ES Fuseline is a single line, but when you translate the formula into YM, some precision can get lost because of the larger nominal values, so the response may need to be treated more as an area/zone than a one-tick level. I know the ES structure much better than YM, so I’d rather be precise than force it :-)
Do you follow/identity Dow Fuse lines?
