Making assumptions on the forum is dangerous because your can make others frightful. Don’t make assumptions. Talk to the source before you say something like that. Otherwise, it’s (unintentionally) spreading disinformation.
Call Ameritrade. Y’all use that. They have a phone number. These new brokers sometimes don’t have that. Use their strengths. Confirm before making assumptions based off of your experience.
Call them if you get warnings. Don’t ignore them.
