Currently, I have cashed out half of my position. The reason is simple: I've hit the middle band of the Bollinger Bands, so I sold half. If it continues to rise, I will hold on and anticipate hitting the upper band. If it drops, my stop-loss level has also been adjusted accordingly. If it breaks my stop-loss level, I will walk away with a profit, which is acceptable. As long as I don't go bust, I will eventually come out on top. If it can stabilize at the upper band, I will participate when it takes off from there, and I should be able to achieve a decent profit.
