No, not necessarily but if Profitable traders used it could be interesting. I have no affiliation to the site, I just saw it on another board and thought I would post here also. But you are correct 26 points in a year is laughable.
The easiest way to trade this market is to buy the extremely negative breadth and sell the extremely positive breadth. You can participate in 15-20% moves every 3 or so months.
why would consistent profitable traders add their calls to the site when they could make money by collecting fees at C2? looks more like a trader wannabe venue.
Obviously to be more profitable, which may or may not be the case (I suspect pump and dump is non-trivial for ES).
