I dropped off a check to Schwab on Friday. My balance is there on the cash side online now, however my checking balance hasn’t changed…

Still waiting on the check to go through despite my Schwab balance updating.

Is it safe for me to trade with my new balance or should I wait for the check to clear?

Friday I received an email from Schwab that it’s been received and processed, not sure if I should wait or not

Please help!
