Notice from TS: "For those of you using the recently-released TradeStation 8.1, Build 2809, please be aware that the overnight and options buying power amounts displayed in your TradeManager and at the bottom of your screen may be inaccurate. Please call the trade desk at 800-871-3563 to verify your actual buying power before opening any new positions. If you do open positions or take other actions in your account that rely on the inaccurately-displayed buying power amounts, margin calls may be triggered in your account. You may receive no warning of this. Accordingly, any actions taken relying on the inaccurate buying power data are taken solely at your risk and we strongly urge you to take no such actions before verifying your actual buying power. We sincerely apologize for this inconvenience, and hope to have this issue corrected within a few days. Thank you for your patience."
