So Greece is having a problem…  This is an OI for SPY expiration date on 7/2 on 6/26/2015. Those numbers at the top are percentage of calls being bought on that day with 7/2 expiry for SPY. It rarely goes about 0.5. For the past few months, when the media is crying wolf, the largest OI and percentage of call bought never confirmed these pending collapse. This time around, it goes to 0.5… (unusually bullish). If market has not priced this Grexit in, then a lot of people would have to sell. On the other hand, if this percentage of call bought is correct again, we should stay within 205.5 and 211.5 (largest OI for put and call;Put is red, call is blue, yellow is the sum)
