Thinkorswim Minimum Balance Requirement
Generally, Charles Schwab does not require a minimum balance; however, specific circumstances do require one. Like most brokers, day trading requires a $25,000 minimum balance. For margin accounts, a $2,000 minimum is needed.
For options trading approval, there isn’t a general minimum balance needed, but you do need $5,000 in marginable equity to hold an uncovered short option position.
Charles Schwab does not require a minimum balance to get advice from their Financial Consultants. You can have a free planning session with a consultant either over the phone or in person at any of their 400+ branches.
Thinkorswim Account Minimums
There are no account minimums required to open any type of account with Charles Schwab. They do not charge fees for having a low balance or for account inactivity, nor do they charge annual or monthly maintenance fees. There are also no minimums needed to access Thinkorswim or its streaming market data.
Thinkorswim Minimum Investments
Charles Schwab offers fractional share trading, so you don’t need to buy full shares of stocks and ETFs. While there are no set investment minimums for mutual funds at Schwab, the funds themselves may have their own minimum investment requirements.
Thinkorswim Minimum System Requirements
For PC users on Charles Schwab’s website, they recommend Windows 7 or newer and the latest versions of Google Chrome, Microsoft Edge, or Mozilla Firefox. Mac users should have at least Mac OS 10.11 and use Apple Safari 11 or later, or the latest version of Chrome or Firefox.
The Thinkorswim desktop platform has specific requirements for PC: at least Windows 10, an Intel Core i3+ processor, 8GB of RAM, 1GB of free disk space, and a 1280x768 display resolution. Mac users need at least Mac OS 10.11+ with the same other specs.
The mobile app from Charles Schwab just requires a smartphone with enough space to download the app.
