Is history repeating?

I notice patterns in things and as shown I show how the down leg from last year could be very similar to what is happening now. This indicates we have around another 15% to fall to complete the pattern.

If the pattern is the same we can expect prices to fall below 3500 within the next 15 days.

I used Fib levels to determine approx. levels.

Note: I only use public indicators in all my charts.
