Until July 1, 2020, if your account value drops below US$25k, we will move you to Stake Unlimited and trading on unsettled funds will no longer be available. We take this precaution because of pattern day trading rules in the US. 

You can make a deposit to bring your portfolio back above US$30k to recommence Stake Black and to trade on unsettled funds.

For a detailed overview of trading on unsettled funds, how to access it and the regulations that sit around it, please read this blog post.
