To enable the shortable feature in TWS, click the wrench icon in the upper right corner to open the TWS Configuration window. Scroll down to Quote Monitor and Default Layout options. Click on the Shortable column and click Add and OK. The Shortable column will now display real-time information on whether a stock is shortable, the quantity of shares available, and the borrowing cost. The colors indicate availability: Red means not available, dark green means shares will be located, and bright green means at least 1,000 shares are available. Mouse-over tooltips provide more details on shares and borrow rates.
