There is two class actions to be,
First is the one them knowing about negative prices and not telling every one, people use a broker to get them through to the exchange, if the exchange gives your firm an advisory prices can go negative common courtesy is you tell your client. When in the world does a trader ever interact with an exchange directly? i never heard of it, a broker is your middle guy
Mind you they got every one out of CL, they did take people out of that position BEFORE, but did not get the ones out QM, that where the trouble is, they knew its gonna be trouble and acted, but only on half the customers the ones in CL instead of QM, which all couldve been eliminated have they simply sent out an email or they couldve raised margin. WHy in 2011 silver they raise margins and here you got crude warnings to go negative and they do nothing about it? till AFTER THE FACT?
Lastly a broker is supposed to allow you to trade. Their platform did not allow trades to be placed when prices went negative. This isnt cry babies this is people unable to place trades when they need to place their trades.
Second lawsuit is about them liquidating all contracts simply because they do NOT want any one to trade crude oil any more, Why? because THEY got burned having reimburse clients that couldn't place orders during prices going negative since they could not place trades and after seeing what can happen all of a sudden they decide its not safe when they knew and had same info before the incident. Incompetence at its finest
