IMO no, just means they are done filling a clients order. I also believe it can be used as manipulation as it makes folks worry about wazup...like you are doing now. Remember the market makers have all taken the class "manipulating emotions 101"
not at all imo...sometimes it is a good sign that a seller is finished and the pps will move up...sometimes the opposite....but i never take it as a bad sign....but that's jmo.. :)
