Hi Thinkorswim shows me the ATH at 2191.50 (cash market). Other brokers shows the ATH at 2184.25. I wonder why this difference. I use as symbol /ES. Same result when "Adjust for contract changes" is enabled. May be other TOS users could confirm my observation.
With ATH i meant All time high. With cash market i meant the regular trading hours. Not Globex. So, my all time high on e-mini is at 2191.50. But i know, other users with other platforms argue, the all time high is at 2184.25.
What month? It is not like a stock. http://www.cmegroup.com/trading/equity-index/us-index/e-mini-sandp500.html
I got it. Some see the ATH at 2119.5. And this is the all time high. Others believe the ath is at 2184.25 (2185 today globex). That's on the current contract. Now we could argue, which is the real all time high. Some people use continuous charts, other only from the active contract.
