My friend has been looking at 15 min charts on the YM. And just by feel he buys, shorts, sells and buys to cover. He knows nothing about trendlines, breakouts, momentum, etc. He trades on just how he feels and I've seen it. When I saw him he won 17 out of 23 trades, with about 10 dow points on his average winning trades, and 10 dow points per losing trade. Is it possible for someone to just trade on feel and be profitable?
