Correction and recovery path based on past performance

I know past performance is no guarantee for the future.....but if the past repeats itself we will get something like this. Around the 2nd of october we will hit a 0.618 retracement level just below 2500. After that you can strap in and hold on to your hat for a ride to between 8000 and 10000.

It is possible we only hit the 0.5 retracement a week earlier and then move up....but that move could collapse and go to the 0.618
