Charles Schwab's thinkorswim platform encountered now-resolved technical problems with its desktop Monday afternoon, a company spokesman said.
"A brief technical issue on the thinkorswim desktop application was resolved earlier. Clients' access to thinkorswim web and the thinkorswim mobile app was not impacted. We apologize for any inconvenience," the spokesman told ThinkAdvisor by email.
Customer problem reports showed up on outage monitoring site Downdetector, where users reported issues under the TD Ameritrade and Charles Schwab banners.
And on X, formerly Twitter, user posts indicated thinkorswim, which Schwab acquired when it purchased TD Ameritrade, wasn't working.
