Simple idea, buy at low and sell at high, here as trader still need to analyze support resistance area or demand and supply, but I think also need cut loss if already away from analysis
When I buy a lower high, it often turned out to be a reversal. I have given up buying retracement. But I like the retracement after a big decline like 8+ points, I'm working on this right now, two or three points with a few contacts, one trade a day is enough.
