this was a little tricky but I have gotten it to work.First you want to get Java 8 installed.Once you install Java,then you need to choose the version cause itll make Java 11 default,once you change it to 8,then the installer runs just fine. Also remember to change the installer to be "executing"(right click,properties,check the box). I think with your case,you should just run this to change it to 8 because I ran into the same issue and once I switched it to 8,I had no problems.

sudo update-java-alternatives -s java-8-oracle

I should note I am using LTS 18.04 but it should work if youre on 18 or 19

Instructions for Lubuntu / Ubuntu 19.04

Thanks to Michael in tech support at Thinkorswim.

The following instructions should help you to install thinkorswim with the proper version of Java:

Installing Zulu OpenJDK:

1. Log in as root or use sudo

2. Import Azul's public key

   $ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0xB1998361219BD9C9
   

3. Add the Azul package to the APT repository

   For Ubuntu

   $ sudo apt-add-repository 'deb http://repos.azulsystems.com/ubuntu stable main'
   

   For Debian

   $ sudo apt-add-repository 'deb http://repos.azulsystems.com/debian stable main'
   

4. Update the information about available packages.

   $ sudo apt-get update
   

5. Install Zulu by using the following command:

   $ sudo apt-get install zulu-8
   

Once Zulu is installed move on to installing ThinkorSwim:

1. Navigate to downloads and right click "thinkorswim_installer.sh", select "Properties"
2. Select the "Permissions" tab, and make sure "Allow executing file as program" is selected
3. Close the window
4. Double click "thinkorswim_installer.sh"

-IF ONLY A TEXT EDITOR OPENS, CLOSE IT AND CONTINUE BELOW-

5. Click back onto the file explorer
6. Open from the top menu bar: Edit > Preferences OR Files > Preferences
7. Select the "Behavior" tab
8. Select "Ask each time" OR "Ask what to do" under "Executable Text Files"
9. Close the window and launch "thinkorswim.sh" and select "Run" from the prompt

I tried and tried and gave up. Now I have Windows running in Virtual Box so I can have ToS on my linux laptop.

I had the same problem. It is like the desktop application window has disappeared. What I did was select the window using Super+TAB and then used the keyboard shortcut to maximize the window ALT+F10. That displayed the application. Then clicking on the un-maximize button made it normal again.

I'm pretty sure that asterisks were some leftover formatting from some wiki probably (they are gone from the source site, you cited), and quotes were there just to emphasize the name...

Why it worked? - Well, double quotes are valid character in filename, you just need to be extra careful when operating on them, to properly escape. Since asterisks were not escaped, I guess, what happened, was that they were probably stripped by the installation script and so you end up with bin" (thing is, asterisks can also be used in filename, but I guess there was at least some sanitization on that input, pity, that it didn't left just a-zA-Z0-9_-. - rarely will you see anything else).

Anyway, I think, you should reinstall it if you want to be sure not to have any troubles running application from that path.

TLDR; it worked, because, in essence, there was no error...

I use ToS on Solus Linux without issue. I've written in this sub a few times about how to optimize it if you're willing to search through.

Make sure you're using the right java distribution and have the paths set up correctly.

I first read "Financial trading of Arch Linux", and here I thought someone had leaked our ICO filing for ArchCoin early.

Call TDA and ask them to update TOS to run natively on macOS with M1/2. The more people call, the more likely they will prioritize this update. It’s been over a year now.

Ubuntu 22.04 LTS 5th gen Intel processor, 16GB RAM, GTX1060 [It's an old desktop machine I inherited and use as a secondary machine.] No fiddling required. Works as expected. I did deviate from the installation instructions slightly. I installed OpenJDK11 from the distro repo rather than Zulu's JDK because it's easier to manage updates.
