I rarely decide upon a stop prior to entry ..I take manual stops most often or preset support and resistance areas, channels , support maybe fibs and M.As and trendlines and the like . It will often depend on how the ticks or runs are behaving as they approach those areas as well as correlations throughout the markets. Sometimes I ll even take an opposite position negatively correlated just to absorb the difference if I think it might be temporary. My mood and how much rest I had in the previous few hours. If it looks like the price is gonna hit a return line like a ton of bricks then I might stop as it maintains a breach but if it looks like its approaching like Tim Conway on the golf course then I am more likely to hold. I am always overcoming hurdles and meeting new ones.
Hah! Interesting, although I feel like fast whips are more likely to revert, and I am more concerned about a slow, methodical price action against me. I suppose the differences are what make the market.
