Sell Xerox @ 10.0- invalid/ win at higher risk

Sell Xerox @ 10.0 if it stays below, for 30 minutes
Xerox's earnings missed expectations

Result: invalid/ win at a higher risk
Although it slightly broke above 10.0 for a while & became invalid, after it failed to stay above, dropped back & stayed below, it should be safe to trade, but at a slightly higher risk
If you traded at a higher risk after it dropped back & stayed below 10.0, Xerox expired @ 9.69 at 10:30am EDT & stayed below 10.0 for the rest of the day
