If I could answer that, I'd be selling DVD's, lol. Here, I give it 84% chance of hitting 77 (have to shave off 0.5 in case the line doesn't get hit right on the money) in the next 4 trading days. 84% comes from the old ascending triangle pattern target % rate, 4 days comes from duration of the pennant being applied from breakout till now.
Anyway, if you want to take some off the table, when you see a reversal candle about to print into the close, make a sale.
