Before GOOG can be shorted, wait for a pretty big price spike, since this is what happened the last 2 times this RSI resistance line was met. Also look for a pretty steep angle and acceleration on the RSI, since this is also happened during the last 2 ideal shorts in late 2015 and Feb 2016. Luckily I was able to short the Feb 2016 drop by using this signal. I hope to get the next short. I will be shorting in the next several days. More risky is to short now, to be safer, wait for the price and RSI acceleration.
