IF count until #3 is correct (BTC won't rally from here on), I would expect it to pullback somewhere around/between 7575 and 7750. This would be our #4. After I would be seeking for #5 somewhere in the middle of current uptrend channel. Why?
1. At 7570 there is .382 Fib level of the whole leg (from 6079 to 8506).
2. #3 is at 1.618 Fib level of the first impulse (from 6079 to 7588).
3. Longer term support/resistance is around 7750 level (red line).
