SPX Elliott Wave Count (EW)

OANDA:SPX500USD   S&P 500 Index
As per EW, SPX is most probably in wave 5 of primary wave 3. I'm expecting primary wave 4 to start sometime in mid-August & may correct up to 20% to conclude wave 4. It's possible that wave 3 ends sooner than expected, but the ideal time according to fib time extension is mid-August.
