Online Broker With Lowest Options Assignment and Exercise Fees

Options Assignments and Exercises Fees

Understanding option assignments and exercises is critical if you're going to trade option contracts. Suppose you buy a call option. This gives you the right, although not the obligation, to purchase the underlying stock on or before the expiration date at the strike price specified by the option contract. When you decide to exercise this right and buy the stock at the strike price, that's called exercise. Assignment occurs when the writer of an option contract is ordered by the clearing house to buy the underlying stock from the option holder (in the case of a put option), or sell the underlying asset to the holder of the option (in the case of a call option). Online brokers charge fees for assignments and exercises.

Broker With Lowest Options Assignment Fees

If Ally Invest has a specialty it is in the options trading business. From their simple and fair pricing ($0 ticket and 50 cents per contract) to the many analytic tools available, an options trader can find all that they need on the site. The screening and pricing tools are too numerous to list in detail, but most impressive are the calculators for probability analysis as well as option profit and loss displays, which will show projected option value for a specific increase or decrease in the underlying stock price, or changes in volatility. All of this is perfect for option traders who know how to use these functions to minimize risk and maximize profit. If one is new to options, Ally Invest also offers education on the site dealing with strategies and option combinations to give all the information needed to begin trading.

For the last 5 years Ally Invest received 4 out of 5 stars in Barrons stock broker survey of the U.S. brokerage firms based on Trade Technology, Usability, Mobile, Range of Offerings, Research Amenities, Portfolio Analysis & Reports, Customer Service & Education, and Costs. The Barrons also named the firm "Best for Options Traders" for the last seven years. We repeatedly rated Ally Invest one of the Best Options Brokers, based on brokerage company's low options pricing as well as on its suite of great tools for options traders.

Ally Invest Option Research and Order Placement

There are some good informational tools on the Ally Invest website for derivate traders. A good place to start is with option chains. This tool appears on the website under the tab 'Quotes & Research' and is also available on Ally Invest LIVE, the broker's trading platform. Typing in a stock's ticker symbol displays call and put options that are near the money. This means the options' strike prices are close to the current stock price. The search tool on the website also allows for options that are away from the money to be displayed. Ally Invest LIVE has the same capability, although scrolling through the results is somewhat cumbersome. Hovering over a bid or ask price of an option produces buy and sell buttons for quick order entry. Alternatively, clicking on an empty square on the left side (calls) or right side (puts) produces a buy (one click) or sell (two clicks) order. Clicking on 'Trade' produces the order ticket. Besides regular calls and puts, Ally Invest's search tool also displays option strategies, such as collars, straddles, and diagonals.

Ally Invest also offers volatility charts and an options calculator. On the firm's trading platform, there is a probability calculator and a profit/loss graph. An options scanner, hosted by, can be launched from the Ally Invest website.

Every Monday afternoon, the broker hosts a live on-line options webinar to discuss options news for the week. Customers can sign up on the Ally Invest site after logging in.

Beyond the website and Ally Invest LIVE, option chains and order placement are available on the broker's mobile app. Traders can use Apple, Android, and mobile web. Unfortunately, sophisticated option research tools are not available on the mobile platform.
