Review chart in detail - remember this is weekly. Yellow flags and dotted lines show RSI peak and directional volume buying at peak.
Green dotted line shows RSI divergence and higher prices before sell off, which is indicated with red arrows. Red line on RSI shows bearish turn. Red oval on DMI shows selling volume increase and buying drop.
Now whether this plays out in a similar manner, time will tell. First look for signs on daily chart, like stochastic moving below RSI, and then both going below 50. I like an entry for Sept. puts between 269-271, but you can also buy one or two at a time and build your position as you see confirmation signals.
