strange ... ET administrator did not remove such threads. This tread has no head no tail. it has just one sentence. I presume his definition of craziness is 'it didn't move according to what he expected it to move' . impact of craziness was not disclosed. time zone and which stocks were not disclosed. or is it the OP suffered loss and is venting his frustration in INTERACTIVE BROKERS folder? perhaps there should a folder VENT YOUR FRUSTRATION for such post.
If you don't see any extra time zone defination, it is always EASTERN TIME. It is standard usage for the stock market. Get used to it.
