TWS Beta - Release Notes

Trade in Fractions

Want to buy just $500 worth of an expensive stock, or looking to diversify among more investments? Now you can - fractional share trading with the ability to enter order size in terms of dollar amounts (Cash Quantity) is in gradual rollout.

How it works: When using a Cash Quantity order, you specify the dollar amount you want to buy or sell instead of specifying the number of shares. Rather than buying five shares you elect to buy, for example, $500 worth of a stock. We purchase the equivalent number of shares for that value rounded down to the nearest whole share. If you enable your account to Trade in Fractions, we will buy or sell a fraction of a share to use the full amount of cash you specified and get the greatest possible number of shares for your money. If you want to spend $500 but one share of the stock you want to buy is currently $1000, you would end up with 0.5 shares.

The ability to trade in fractions also makes it easy for you to diversity your portfolio; if you have $500 to spend you can purchase fractional amounts in multiple companies when you otherwise might only be able to purchase whole shares in two or three companies.

To use cash quantity for an order, click in the Quantity field to display the Size Wand, and toggle to USD (or relevant currency). Specify the cash amount you want to use. When the order fills, it will fill as close as possible to your specified amount, rounding down to the nearest whole share if you haven't enabled trading in fractions. See below for more details.

To enable fractional share trading, log into Client Portal and select Settings and then Account Settings. Click the gear icon in the Trading Experience & Permissions section and expand the Stocks section. Check United States (Trade in Fractions) to enable. This feature is available to both IBKR Pro and IBKR Lite clients, and supported for a subset of US stocks.

Cash Quantity for Stock Orders

Now you can specify the cash amount you want to spend or receive for your stock orders using the Cash Quantity feature. When you specify a cash value for your order, that value in conjunction with the instrument price drives the number of shares purchased or sold. If the price moves, the number of shares is adjusted to accommodate the entered cash value. Shares are rounded down to the nearest whole share. For even more precision, enable your account to Trade in Fractions. This eliminates the need to round down and uses the full amount of cash value.

To use Cash Quantity for a stock order, click in the Quantity field and toggle the size calculation method from Shares to USD (or the currency of the instrument). Enter or select a cash value and see the approximate share equivalent directly below. Shares are approximate until the order fills.

Because the price may move before the order fills, we apply a "Cash Quantity Estimate Factor" when calculating the order quantity. This factor, set to 25% by default, increases the calculated order quantity to try to achieve the desired monetary outcome in cases where the price drops (for a buy) or rises (for a sell) by allowing more units to be bought or sold. You can change the default "25%" in the Size section of the Stock preset in Global Configuration.

Cash Quantity for Stock Orders

The Cash Quantity feature is available for stocks orders in all currencies, and is supported for almost all order types and IB Algos.

Advisor Model Marketplace

The new Advisor Model Marketplace is a searchable database of downloadable investment model compositions. Models are designed and offered by third-party vendors, at no cost, to RIAs for use with their own clients. Once you are subscribed to this feature, you can browse the available vendor models or search by filtering on desired Risk, Asset Class, Rebalance Frequency and other attributes. Once you find the model you like, download it as a .csv file, then import it to TWS to use for your clients.

To use models and access the Model Marketplace, you must first enable Model Portfolios in TWS and then enable Model Marketplace. To do this:

  1. Log into Client Portal.
  2. Select Settings then Account Settings.
  3. From the dashboard, click the configuration icon next to Model Portfolios and Model Marketplace services to subscribe.

Once you are subscribed, log into TWS. Open the Advisor Setup page (from the toolbar, of from the Portfolio page by selecting Models Setup from the Display Selector). From the Models tab click the Browse Vendor Models button. This opens the marketplace.

Browse the marketplace to find a vendor model. From the model page, click Download composition in the bottom right corner to download the .csv file. By default this file is saved to your downloads directory or wherever you have specified downloaded files to be saved.

Back in the Advisor Setup page, Create a model. Next, open the Rebalance window select this newly created model from the Select Account list. Click Import and find the downloaded model in your downloads folder to open. Modify percentages and fine-tune the model composition for your clients.
