Why would arbitrage push it to 1667.50? Why not 1690.00? Why not the high OI strike? Why not base these trades on lunar or menstrual cycles? Good luck with the puts.

let's see if I can scalp .70c

GOOG
+ 4 March 390c @ 6.05
I consider my trading today in GOOG to suck BIGtime. Exited the deep 340c 5 points to soon (i.e. missed $500 profit in next hour). BUT I did immediately place an order rolling into GOOG March 370c @17 --- but missed that due once again to getting too cute and not entering a MARKET order.
I did hold my long 400c, but then sold them .70 too soon (= $560 lost profits)!
