A multi-system market outage affected many of the largest brokerage firm platforms early Monday, with clients taking to Twitter to voice their frustration.
The troubles came on the same day Apple enacted a 4:1 stock split and Tesla's shares were split 5:1, and as the Dow Jones Industrial Average reconfigured three holdings. The issues were largely resolved later on Monday.
Investors using TD Ameritrade, Charles Schwab, Vanguard, Robinhood, E-Trade and other sites said they were experiencing issues in the morning.
For TD Ameritrade, some users stated on Twitter (under the hashtag #TDAmeritradedown) that weren't able to access some mobile applications.
The brokerage's system was down at 9:37 a.m. Eastern time, according to Downdetector, which said the number of site problems peaked at about 7,300. Most users, 76%, said they had login issues, with 15% reporting website access troubles and 7% difficulties placing trades.
A TD Ameritrade spokesperson said at 12:45 p.m. that issues were being addressed: "Clients are able to access their accounts and trades are being processed as usual across all TD Ameritrade platforms."
Earlier in the day, "many clients experienced high levels of slowness on the TD Ameritrade web platforms and the TD Ameritrade mobile app," the spokesperson added. "During this time, the thinkorswim desktop and thinkorswim mobile app were not impacted."
Later in the afternoon Monday, TD Ameritrade said it's issues had been resolved. "We're working with impacted clients to address any concerns they may have. We apologize for the inconvenience and take the performance and reliability of our trading platforms very seriously," it said in a statement.
