It's the statement below that has led me astray I think. How I interpreted it: It states that the rule comes into full effect tomorrow.  And as a result of that rule, "This means....".  In other words, as a result of the rule, no more buys or sells after today.  And obviously, an SEC rule doesn't apply just to TD customers.

BUT, rethinking it, and from what you posted, it doesn't make sense.  I'm now inclined to think it's just a TD policy thing for TD customers only and does not apply outside of TD.

"....On Wednesday, November 23, 2022, this rule will come into full effect. This means all BUYs and SELLs for securities listed in the U.S. Expert and Grey OTC Markets will be rejected and all open Good Til Date (GTD) orders will be cancelled. All closing transactions will no longer be permitted...."
