Download for Linux
Run the Windows installer and TapeSim sets itself up (Start Menu shortcut) and keeps itself up to date automatically — no .NET runtime needed. Prefer no install? Grab the portable zip and run the app directly. On Linux, unzip and run. A macOS build is planned for a later release.
Running the installer on Windows: TapeSim isn't code-signed yet,
so Windows SmartScreen may show "Windows protected your PC." Click
More info → Run anyway to install TapeSim. (Code signing is coming.)
Activating your license
TapeSim is free to open in viewer mode — you can browse the chart, Level-2 book, time & sales, and DOM ladder for any market day. Sim trading is unlocked with a license.
- Don't have a key yet? Start a 7-day free trial — your license key appears in your Polar customer portal (linked from your receipt email).
- Launch TapeSim. On the gate screen, paste the license key and click Activate.
- That's it — open a market day and your sim trading is unlocked.
New to TapeSim? The documentation walks through downloading a market day, the trading screen, and the DOM ladder.
Changed machines? Each license activates on up to 3 machines.
If you've upgraded or replaced a PC and run out of activations, open your
Polar customer portal, find your license key, and deactivate the
old machine to free a slot — or email
support@tapesim.app and we'll help.
Free trial: new subscriptions start with a 7-day free trial. Cancel
anytime before it ends from your Polar customer portal and you won't be
charged. See the Refund Policy for details.
