S&P 500 short elliot wave

In the fibonacci rec you can see the measurments are like textbook elliot wave. Wave 2 is typically 50% of wave 1, wave 3 is typically 161.8% of wave 1 Wave 4 is typically 8.2% of wave 3. I see a strong bounce back a little over 2600 which gonna be the best point to short. I think we've tested the lows for now and the bounceback is gonna come soon. When we hit the 2620 mark either is gonna come the big crash ore we gonna stay at a level between 2200 and 2600 cnstantly through summer.
