Doc:
I am by far no expert. Just a greenhorn. The general rule is that when there is an inside day, you buy a breakout above the high of the inside day or short a break to the downside below the inside day's low. In this example, you would have bought at 23.61 or shorted at 23.19. Given that it was four inside days in a row, the buy/sell signal should be much more significant.
Fwiw, I shorted sugar at 24.13 near the mini double top after it rallied hard and finished near the high following the previous down day. Also, has I not been short already and in the trade or if I had more capital, I would have leaned very hard against the 23.60 area this morning. I thought about shorting more at 23.50 after it moved up to 23.50, but I couldnt pull the trigger.
I like to lean hard against areas of resistance and support. Additionally, if you look at the four consecutive inside days, the lows were all almost identical while the highs for each day collapsed a greater distance towards the successive lows. My eyeball test perceived that as being a very bearish sign.
But again, I have only been trading for a few weeks so please take what I say with a giant grain of salt.
