Is there some consensus among traders about what the exact all time high was in ES futures last July ?
I'm unsure because I see different prices being quoted by different people on blogs, forums etc.
It seems people are using different settings in their historical charts.
eg In Sierrachart there are several settings --back adjusted, date-rule rollover etc.
As it may test up there sometime soon, I'd like to know which price most market participants will see as the high of last year. My current settings on the daily chart show it at 2105.

I may be wrong but different prices may be the result of which specific contracts traded at which level. CQG does that for example.

Just use the cash SPX index or the SPY etf. Hen when those are at the highs, the futures are at the highs.
