    Follow the market

    The table updates every second with each stock's price and change; pick one and the chart shows its latest prices.

  2. Step 2: Buy and build your portfolio

    Buy and build your portfolio

    Choose the stock and quantity and press Buy (with its commission). At the top: cash, shares value, net worth and gain or loss.

  3. Step 3: Sell and review your orders

    Sell and review your orders

    Each sale goes to the Orders tab with its result. The portfolio is saved on your computer and is still there next time.
