DepthFeed — Paper Trading

Paper trade with native Polymarket and Kalshi buttons. Track virtual balance, open positions and P&L in your paper wallet.

Paper trade with the buttons you already use. Enable Paper mode for a supported Polymarket or Kalshi tab, then click the site’s existing Yes, No, or other supported outcome button. DepthFeed records a simulated buy using virtual funds. The exchange’s buttons, charts and layout keep their original design. A small Paper mode label by the platform logo and a PAPER badge on the extension icon identify the active mode. Paper mode starts off and is enabled separately for each tab. YOUR PAPER WALLET Open the toolbar wallet to choose a default stake, switch Paper mode on or off, connect your DepthFeed portfolio, check an unresolved request, or view open positions, marked value and P&L. There is no persistent sidebar and no duplicate market chart. GET STARTED 1. Open the extension to create a free DepthFeed account or log in. Google and Apple sign-in open DepthFeed’s existing secure sign-in flow in the same Chrome profile. 2. Create a portfolio with $10,000 virtual cash, or connect an existing webhook portfolio. 3. Open a supported Polymarket or Kalshi market page. 4. Choose a paper stake and turn on Paper mode in the toolbar wallet. 5. Confirm the Paper mode label, then use an existing outcome button. If the native trading ticket has a uniquely associated Amount field, that amount takes priority over the wallet’s default stake. Paper buys use market pricing from DepthFeed’s server. Close paper positions directly in the wallet’s Positions tab. The DepthFeed web tracker is optional for full trade history. PLANS Free to install; a verified DepthFeed account is required. DepthFeed plan limits apply. The Upgrade link opens DepthFeed pricing for additional paper strategies and research tools. The extension makes no purchase. SIMULATION Virtual funds only. The extension does not sign wallet transactions or send real exchange orders. While armed, it intercepts supported native outcome controls and blocks native final order controls. Ambiguous contracts fail closed. This is a simulation workflow; fills, liquidity, slippage, fees and settlement coverage can differ from real trading. PRIVACY The extension uses your existing DepthFeed session and stores account-scoped paper connection tokens, preferences, outcome labels and unresolved request references locally in trusted Chrome storage. Paper credentials are sent only to DepthFeed. Public market URLs and outcome identifiers are read only on the supported exchange hosts for contract mapping. There are no extension analytics, advertising trackers or remote scripts. DepthFeed is independent and is not affiliated with or endorsed by Polymarket or Kalshi.
