Quote from Cutten:
One example is from Nov 18th in the morning session. There was an initial selloff of about 4 points, then the market reversed back and took out the high of the day by a couple of ticks, at 1185.50. However it stalled there instead of generating further momentum, making it likely that this was a "fakeout" move triggering stops slightly beyond the high of the day, rather than something likely to build into a further rally to new highs. When the market started to reverse, I considered it a reasonable trade to go short with a close stop just above the 1185.50 level. I sold 1185.00 and placed my stop at 1186.00 (although I may have exited earlier if the market did not start selling off within a certain period of time, or if strong buying suddenly came in). There was a recent support low at 1183.50, so I bid 1183.75 to cover, and indeed got filled there a few minutes later, without any meaningful move against my position.
