Earlier quoted context omitted.
Sure, no argument from me on here. You have to admit, though - that is disingenuous. Those plays were profitable, no need to call them (unless there has been irresponsible behavior on the behalf of the broker)
That is entirely up to the broker. They make no guarantees to you that they'll underwrite your risk taking with no limits. If you don't want this to happen, go to a reputable broker and make sure you are not trading on margin. This is not rocket science, but does require a basic level of understanding.
The fact does remain, though, that the way the data is presenting itself seems to indicate that there was disingenuous behavior on the behalf of market makers and a number of hedge funds. To be seen, I guess.
