It's funny when an MM comes on duty and my limit order which has been in place all night and all morning (not rejected, and standing firm), gets rejected due to "invalid price." Then, after resetting and putting back in place and standing firm for several minutes, gets rejected not once, but three more times, for "check price," then "out of range." I am recording this activity and if it happens again, will report it to the FINRA and the SEC.
