But they price an SPX 1800P at $0.50 that expired 6/13/14.
It expired, its price should be 0.00 not 0.50. (SPX is 1935)
correct...so call IB and complain. The SPXW options expired and settled Friday. SPX options that are monthly, settle am but expire Saturday, but their price should be zero too, since the CBOE and OCC has that as the settlement price.
