When I hear these claims of not getting filled, I wonder why folks don't place their order by phone. Any concerns or questions can be answered by your Broker... that is, if folks "really" want an answer... don't you think? Anybody can claim their orders are not being filled...so tell us what your Broker says.
Common sense, I would think.
In pennyland, most things are not as they "appear". Know when to buy...know when to sell.
