FAQ - General

It is safe to use thinkorswim ® Sharing?

In designing the thinkorswim sharing system, we were very aware of the security concerns some users may have so we took several steps to ensure your data is protected. The technology for sharing has been built into thinkorswim since early 2013; we have performed an internal security review and all of the data required to create the Sharing links is handled by our technology via our secure backend servers, not on your local computer or the public Internet. Only data that is validly shared from inside the thinkorswim application can be communicated via the sharing links themselves.

When a user clicks on a Shared link, the only information that is passed from the browser to the thinkorswim application is the sharing link pointer; all other data is delivered by our secure servers directly to the thinkorswim application. This ensures only valid data is retrieved and shared. Your account and other personal information is not shared, but if you have a public MyTrade profile then that public display name is used.

myTrade is a service of myTrade, Inc., a separate but affiliated firm. TD Ameritrade is not responsible for the services of myTrade, or content shared through the service.

How do I delete a thinkorswim ® Sharing link?

All thinkorswim Sharing links cannot be redirected or deleted. If you'd like to remove a link from your thinkorswim platform, go to the Tools tab> Shared Items > and you can click on the 'X' next to the link you wish to remove. ‘Removing’ means you will no longer find the thinkorswim Sharing link in the "Shared Items" view.

Will I still be able to use Quicken once the conversion is complete?

Yes but it will not support futures or FX downloads. The Futures trading gain or loss is provided on the futures 1099, which is separate from the securities account 1099. If there was more than one 1099 issued (this may be the case for 2010 and 2011) you will need to combine the totals from each statement for the year-end gain or loss.

TD Ameritrade does not report to the IRS for Forex trading and you should speak with your tax professional as to how this should be included in your filings. Trade summaries can be generated in the thinkorswim software under Monitor>FX Statements. Be sure to choose the date of 12/31 from the previous year and 1/1 to the following year. For example, if you are pulling information for 2011 you would enter the dates 12/31/2010 – 1/1/2012 as this will cover any trading or unsettled gain or loss that was opened or occurred during the New Year’s transition.

How do I add/remove a gadget to the sidebar?

To add another gadget, click on the oval-shaped wrench button at the top of the left-hand sidebar. This will add an icon to each of the existing gadgets in the sidebar. By clicking on the green plus symbol you can create another gadget or delete an existing one by clicking on the red slash. To change the gadget to a different type, click on the "Gadgets" button on its top-left corner. To remove the add/remove gadget icon, simply click on the oval-shaped wrench button again.

How do I switch between accounts?

In the “ACCOUNT INFO” pane and the top of the sidebar there is a pane that says “Active Account”. Using the drop-down menu there, you can switch between any account linked to your current user name or a total account view which links every account for that user.

How do I hide account information?

If you are in a semi-public location, or showing the platform to a friend, you do have the option to hide your personal financial data while still using the platform. To activate this feature, click on the blue circle button to the left of your “Net Liq & Day Trades” in the “ACCOUNT INFO” panel. In the screen that pops-up there is a checkbox that says “PRIVACY”. Check this box and all of your specific account data will be hidden throughout the platform. Uncheck that same box to view those details again.

How do I import/create/delete/edit watchlists?

The watchlists that you have created in any other TD Ameritrade platform should be visible within the thinkorswim trading platform. For example, if you have created a watchlist on the website, it should appear under the “Personal” section of your watchlists. To create a new watchlist click on the MarketWatch Tab, and click on “quotes." Right click on sub header bar below “quotes” and select the option to Create New Watchlist. In the next window, you will be prompted to input a name for your watchlist. You can either add the ticker symbols you wish to monitor manually by typing the symbol in the blank box, paste symbols from the clipboard or you can upload a .CSV or Excel file. Then click import. Click on the “import” button. You can either by right clicking the same sub header bar you used to Create New Watchlist, you can customize columns, edit, create, or delete a watchlist.

How to sort or unsort watchlists?

You are able to click and drag any security to where you wish within the watchlist. To sort the list in ascending order (A-Z), left click on the sub header ”symbol” directly below the header “quotes”. To unsort the list, left click the tab “symbol” again. If the list is sorted in ascending order a shaded gray arrow in the tab “symbol” will be pointing up. The arrow will be pointing down if the list is sorted in descending order (Z-A).

Can I get rid of the left sidebar or get it back?

Certainly. At the top-left hand corner of your screen, immediately to the right of the “Home” button, there is a blue arrow pointing downward. Click on this arrow and your sidebar will be minimized until this arrow is clicked again.

Where do I find the messages that popped up (reject messages, chat room alerts, etc)?

To find previous messages, click on the circular button in the top left corner of the screen. This button is marked by an exclamation point in the middle of the button.

My platform seems sluggish, how can I speed it up?

The first thing to try is to adjust the Java memory settings in the platform in the “Configure…” menu in the lower-left hand corner of the login screen of the platform. By default, these are set to a minimum of 32MB and maximum of 512MB. Setting these higher can improve platform performance if your system has the RAM available. We do NOT recommend setting both the minimum and maximum to the same size however, as this can prevent Java from performing garbage collection (clearing irrelevant data) which can actually degrade platform performance. Large numbers of chart windows and studies on those charts use significant resources on your computer, particularly if your computer is running multiple monitors. If you notice slowness under these circumstances, limiting the number of charts and studies used at once can alleviate it. If the problem persists, contact our Technical Support department.

What is MMM?

MMM, or Market Maker Move, measures the expected magnitude of price movement based on market volatility.  It measures the implied move based on volatility differential between the front and back month.  The MMM helps to identify the implied move due to an event between now and the front month expiration (if an event exists).

What is implied volatility?

Implied volatility is an estimate of the volatility of the underlying stock that is derived from the market value of an option.  Implied volatility is the volatility number that, if plugged into a theoretical pricing model along with all the other inputs, would yield a theoretical value of an option equal to the market price of the same option.

Futures Intraday Margining is the reduced holding requirement as compared to the initial or overnight margin requirement for futures trading available intraday.  The rate is generally 25% of the margin requirement for a particular product but can change at any time without notice.  The minimum net liquidation value of $15,000 is required to be eligible.  Intraday margin applies between the hours of 8:30 a.m. CT and 3 p.m. CT.

How did the Google corporate action effect my thinkorswim chart?

Google Reorganization on thinkorswim Charts.

On January 30th Google, Inc. (NASDAQ:GOOG) announced that its Board of Directors approved the distribution of Class C shares to its stockholders. The Google Board of Directors has approved a distribution of shares of the Class C capital stock as a dividend to stockholders with a dividend record date of March 27, 2014 and a dividend payment date of April 2, 2014. The two types of shares are quoted under the symbols GOOG (Class C shares) and GOOGL (Class A shares.)

GOOGL (Class A shares)
Google’s original class A shares went through a distribution which reduces the price of these Class A shares by the distributed price of Google Class C shares. The historical price and volume data of the original class A shares with symbol GOOG has mapped over to symbol GOOGL. The price data was adjusted for the distribution of the Class C shares. This adjustment was made to historical prices prior to the listing of the ex-date Class A Shares, GOOGL.

The formula for the adjusted price data of the Class A shares prior to April 3, 2014 is:

i * (G – C) / G
i = Unadjusted OHLC Data for GOOG on or before April 2, 2014
G = NASDAQ close price of GOOG on April 2, 2014
C = NASDAQ close price of GOOCV (Class C Shares) on April 2, 2014

Historical Volume data has not been ratio adjusted due to the nature of the distribution.

GOOG (Class C shares)
In order to maintain a consistent experience after this unique reorganization we have applied the same logic to provide historical data on the Class C shares. This adjustment was made for historical prices prior to the listing of the “when issued” Class C Shares, GOOCV. The price and volume data from March 27, 2014 to April 2, 2014 were derived directly from the unadjusted GOOCV prices.

The formula for the adjusted price data of the Class C shares prior to March 27, 2014 is:

i * (G – A) / G
i = Unadjusted OHLC Data for GOOG on or before March 26, 2014
G = NASDAQ close price of GOOG on April 2, 2014
A = NASDAQ close price of GOOAV (Class A Shares) on April 2, 2014
Historical Volume was copied over from the original Class A shares and has not been ratio adjusted.

Please note that all of this price data prior to April 3rd 2014 for the Class C Shares is a synthetic representation based on the reorganization described above. The volume data prior to April 3rd 2014 is the volume of the data for the original Google Class A shares.

How do I save my platform settings?

There are a number of ways to save different settings, i.e. drawings, charts, styles, etc. These are saved server-side, meaning they will be persistent regardless of the computer you login with. To save your currrently viewed settings, click on “Setup” in the upper-right corner of the platform, then “Save Workspace as…”, designate a name for the workspace and press OK. These are saved locally to your computer, so they will not be available if you log in using a different computer.

How do I move my settings from one computer to another?

Pull up all the settings that you would like to transfer from the first computer (detach your grids, charts, analyzed trades, etc), then click on Setup>Save Workspace As and give it a name. This will create a file in the thinkorswim® directory (c:\program files\thinkorswim) with a name called workspace.whatevername.xml. Basically anything that displayed on the screen when the workspace is saved will be transferred.

*If you have several grids, open each of these and detach them so that they are displaying on the screen prior to saving the workspace.

Then go to the thinkorswim® directory:

  1. Exit the thinkorswim® software
  2. Right click on the thinkorswim® icon
  3. Left click on PROPERTIES
  4. Left click on FIND TARGET (Windows VISTA/7: Select SHORTCUT tab and left-click OPEN FILE LOCATION)

In the thinkorswim® folder you will see a folder called Backup (this folder may not exist) as well as files named workspace.*.xml. Move all of these to the new machine. You will then be able to pull up these settings when logging in with the saved workspace you transferred. Once the detached charts load you can then save all the necessary settings to your other computer accordingly.

For Watchlists:

Export the watchlist by clicking on the printer icon on the top of the watchlist and select ‘Export’. Then save this file in CSV format to your computer. You should be able to import this same watchlist to the platform on the new computer once you have transferred this file as well. Once logged into the platform, click the small gear button on the top of the watchlist in your gadgets or in MarketWatch>Quote and select ‘Create New Watch List.’ Next, click ‘Import’ and select the file (you may have to edit this file prior to import and remove anything that is not a symbol).

How can I change the background color and font size?

To customize application Look & Feel preferences such as color scheme or font size:

1. Press Setup in the top right corner of the window and choose Application Settings... from the menu. Click Look and feel in the left panel.
2. Choose one of the available color schemes: dark, bright, or old school TOS. The former two are also available in high contrast.

How do I add money or reset my PaperMoney account?

Click this button then confirm, and all of your positions will be reset to zero and your account net liquidation value will be set back to $100,000.

If you simply want to add or remove cash in the account, right-click on one of your positions in the paperMoney account and you will see an option to “Adjust Cash” or “Adjust Forex Cash” in the contextual drop-down menu.

To remove a single position from your PaperMoney account, right-click on that position in the Position Statement and select "Adjust Position" on the drop-down menu. Click this, and on the menu that then appears enter the number of shares/contracts you would like to remove and the cost per unit that you would like to pay/recieve. Click "OK" and you're all set.
