I worked out the percentage drops for you. So at the very least we can expect 30% drop... so thats the 5800 range unless this is phase B of an elliot wave and then it's probable to go much lower.

And how many of those are downtrends rather than corrections? And for how many of them did the price drop instantly when the RSI hit 77? Technical indicators are just a derivative of price or volume. They are nothing special on their own.
