A break will occur soon one way or the other. If you think a bull pennant will occur set a target price of around 8.49 higher from where ever the break of the upper support happens, with a stop just bellow the lower support line of the triangle.
The upper resistance of the triangle broke as predicted, and now the major resistance point of the pennant has been reached. Stochastic suggests FB is now oversold, but that doesn't mean it won't still go higher. It would be prudent to take some profit now and let the rest ride if you think it can make it to the target of price of around $68. You've made some money, so start paring down your position. Don't turn a win into a loss.
