How many calls per ES contract?
I have proprietary formula that I don't hand out. But based on open interest, volume last two hours. I follow 42 futures markets on my method and been trading it since 1993/1994. Only in last two years have I made changes, I tend to backtest in decades and not years. I don't concentrate on making profits, but do concentrate on low losing percentages, this allows me to average down. I do this on long term trading of commodities, stocks, ETFs, spread trading, stock options and day trading. If you not losing much, account has one way to go.
