No, his health was declining for years while he was mentoring, which is why he retired (and stopped trading). His heart attack came in November last year just from deteriorating health. Trust me, if he had not retired and had been trying to trade after Feb 2018, his heart attack would have come sooner. Because his system was a slower-scalping method. The ES was such a slow mover through out my training years, 2014-2017, he called it the "EverSlow", and rarely traded it. He was always saying "trade what moves". ES was always the shittiest slow-mover back then. We'd dive into more exciting bits back then like CL, GC, NQ, 6E, NG, RB, and occasional treasuries like the Zs, Corn, Copper. The key was to trade what moved the most, and to plan to trade what the market did MOST of the time after a certain move intraday.
