Once you are done tweaking filters & criteria to arrive at your screen, you can start adding stocks from the screening results to create smallcase and invest in it immediately.    

Follow these steps to build your smallcase/portfolio.

1. To add a stock to create your smallcase, just click on the “+” button in the header next to Name.

2. Once you have added all the stocks, you can click on "Create smallcase" at the top right of the table to buy the created portfolio. Remember you will have to select the stocks individually here.

3. Clicking on "Create smallcase" button will redirect you to your broker platform, where you can complete the buying process. ( You need to connect a broker account into your Tickertape account for this).
