So the "class action" is a whopping three people who obviously lost their asses because they didn't know what they were doing, so now they're trying to pull the victim card and blame their losses on the broker.
This brings us to what I consider to be the #1 lesson for every person who decides to start trading:
Take 100% ownership of your actions. And I mean 100%. The consequences of your trading will always be a direct reflection of the choices that YOU MAKE.
And the same principle applies in every other aspect of life:
Your choices will always dictate your outcome. That's it. The choices you make for yourself, the choices you make for your family, and the choices you make in regards to who you associate with will determine the outcome you receive in all of those areas.
If you ever want to read a good book in regards to this topic, here's one I recommend. It has a military slant to it, but it still applies to every area of your life.
The bottom line is that any of those traders in the complaint could have exited their positions well before crude went negative. But they didn't. And because they didn't, and because they can't accept responsibility for their own choices, they are now choosing to cast the blame on someone else due to a scenario that never happened before in the history of crude trading prior to that date.
