You can upgrade your account by simply requesting it through the app.
To do so, navigate from the Homepage to More>Account Details>Account Profile and Select Change Account Type.
In order to upgrade you need to meet the following qualifications:
-All Trades Settled
-All Funds Settled
-No Open Orders
-Net Account Value >$2,000
-Exit the Stock Lending Income Program
-No options position
Trades take two days to settle and need to be done before you can upgrade your account. Funds from incoming, outgoing deposits, and trades need to be fully settled and not in transit. Unfilled orders need to be canceled as well. Equity needs to be above $2,000 in order to upgrade to a margin account. The stock lending program needs to be exited. The Stock Lending Income Program allows your shares to be loaned out so other stock market participants can short stocks. You earn a small percentage of revenue for the rates those participants pay to borrow the stock. In order to upgrade you need to unenroll from this program. Lastly, no options position should be held either before you apply for it. Otherwise, your application will be rejected.
Once you submit a request to upgrade to a margin account it can take up to 6 days to complete during which this time you can not trade. Due to this, you may wish to close positions so you do not have market risk during the upgrade. Additionally, positions undergoing corporate actions may further delay the time it takes for an account type to change over.
