Customers requesting to exercise US or Canadian warrants should submit a ticket in Client Portal via the Message Center. Select the User menu (head and shoulders icon in the top right corner) followed by Secure Message Center. Select Account Services as the category and Corporate Actions/Dividends as the topic. Only settled warrants can be exercised.
Tickets should include the following information:
- Request Title should be “Warrant Exercise Request”
- The warrant Name and Symbol (no need to specify the CUSIP of the warrants)
- The stated action (“Exercise”)
- The Account Number and EXACT Number of Warrants you wish to exercise (“ALL” is not a valid instruction)
- Agree to the terms and, if applicable, indicate whether the exercise is a Cash or Cashless exercise
The broker will pass through all associated exercise costs to the customer upon completion of the request.
Cash exercises typically take 1-2 business dates for the warrants to be converted into shares. Cashless exercises typically take 2-3 business dates for the warrants to be converted into shares.

How is my volatility being calculated?
Implied volatility measures the uncertainty of the underlying’s price implied from the options prices.
Implied volatility is calculated using a 100-step binary tree for American style options, and a Black-Scholes model for European style options. Interest rates are calculated using the settlement prices from the day’s Eurodollar futures contracts, and dividends are based on historical payouts.
The 30-day volatility is the at-market volatility estimated for a maturity thirty calendar days forward of the current trading day. It is based on option prices from two consecutive expiration months. The first expiration month is that which has at least eight calendar days to run. The implied volatility is estimated for the eight options on the four closest to market strikes in each expiry. The implied volatilities are fit to a parabola as a function of the strike price for each expiry. The at-the-market implied volatility for an expiry is then taken to be the value of the fit parabola at the expected future price for the expiry. A linear interpolation (or extrapolation, as required) of the 30-day variance based on the squares of the at-market volatilities is performed. V30 is then the square root of the estimated variance. If there is no first expiration month with less than sixty calendar days to run, we do not calculate a V30.
What is the deadline for providing notification of option exercise?
In the case of U.S. exchange listed options cleared by OCC, GPS’s deadline for providing notification of intent to exercise is 17:30 ET if the option is being exercised prior to expiration. At expiration, notice of intent to exercise is generally not required as OCC will automatically exercise options that are in-the-money by $0.01 or more.
If a client is required to provide notice of intent to exercise at expiration (i.e., OCC removes contract from Exercise by Exception processing due to a stock halt or other uncertainty as to underlying value) or does not want an option that is projected to be in-the-money by $0.01 or more exercised, then instructions must be provided to GPS by 17:30 ET.
Where can I find SPX weekly options?
In the TWS Option Trader or TWS/Mosaic Option Chains window, click on the drop down menu that says SPX in the upper right corner of the option chains. Select SPXW as the Trading Class and the screen will change to the SPXW Weekly options. The rest of the available weekly expiries can be found by clicking on the More tab to the right of the currently listed expiries.
When are warrants exercised?
In the U.S. and Canada, the depository will accept requests to exercise warrants up to 13:00 ET.
Instructions received after that time will be considered for exercise on the following trading day.
What is the minimum balance required for trading options?
If you already have option trading permissions and a Reg T margin account, the minimum balance required for trading options depends upon the following considerations:
- If you are looking to purchase an option, you need to have the funds necessary to pay for the option in full.
- You are required, by regulation, to maintain account equity of at least USD 2,000 to retain margin eligibility. If you do not, you would not be able to sell options on an uncovered basis. If you do maintain account equity above USD 2,000, you would still need to have sufficient equity to satisfy the margin requirement were the sell order to be executed. If you do not have sufficient equity, your order will be rejected.
Can I short a warrant, structured product or certificate?
Warrants, structured products and certificates cannot be sold short nor bought on margin at GPS.

How do you calculate historical volatility?

Can I exercise warrants for cash if I do not have available funds?
No. In order to exercise warrants for cash the account must hold sufficient funds available for withdrawal to pay the full cost of the warrant exercise.
How does a corporate action affect my option contract?
If a corporate action such as a merger, acquisition or spin-off occur before the expiration of your contract, the clearinghouse will typically announce an adjustment to the amount or name of the security deliverable under the contract. When such adjustments occur, the party delivering the underlying (i.e., short holder of a call or long holder of a put) is obligated to deliver the adjusted security at the option strike price.
Can I exercise newly purchased, unsettled warrants?
All warrants must be settled in order to submit for exercise.
Please note, warrants listed on European exchanges cannot be exercised before expiry. They will auto-exercise at expiration if they are in-the-money, otherwise they will be removed as worthless.
If I close my short option position before the close, am I at risk of being assigned on that contract?
Option assignments are determined based on net positions after the close of the market each day and if you bought back your short contract, you no longer have a short position at the end of the day and no possibility of assignment.
Can I submit instructions today to have my warrants exercised in 3 days?
No. We do not accept requests to submit warrant exercises in the future. Exercise requests are submitted for processing on the same day, provided there is sufficient time to meet the depository’s processing schedule.
Please note, warrants listed on European exchanges cannot be exercised before expiry. They will auto-exercise at expiration if they are in-the-money, otherwise they will be removed as worthless.
