Last night sees GOOG Nov07 $650 Put goes from $5.80 lowest to $28.10 highest. It closed at $23.30.
There's 2 ways to enter a put on last nite's 15min chart.
Way 1 : Support breakdown at $656 level (buy put @ $12)
========================================

Way 2 : Triangle breakout at $660 level (buy put @ $8, thus cheaper)
========================================

However, the Nov07 650 put option chart only sees breakout of the option price range at $656 support breakdown, thus way 1 is more achievable.
