MU expires

#LongCalls My shot at a long trade didn’t pan out. This is why I never used to buy options; too hard to determine when to close. Could have taken only a small loss had I sold at the right times Monday, Tuesday, or Wednesday! How many times does the market have to tell me before I’ll make the move?
Expired: $MU Oct 5th 45 long calls, bought for 2.02 on Sep 14th.
