Select the exact outcome after the extension detects the event’s available outcomes. Free covers longer candle intervals; Pro adds shorter views, indicators and multiple-outcome comparisons. Charts offer historical price context, but they are not executable order-book quotes. The exported volume series is described as proxy volume rather than a complete record of trading. Desktop alerts use background checks at 60-second intervals, so they are polling-based browser notifications rather than tick-level or server-side monitoring. Panel and alert preferences are retained locally, while Pro entitlement validation uses the provider’s external service. ### Who it is for - Users who prefer OHLC candles to probability lines. - Researchers comparing price histories across outcomes. - Desktop users configuring market-price notifications. ## Features and coverage - **Floating event panel** Move, resize or minimize the chart and load the event’s automatically detected outcomes. - **Free candle views** Use 1-hour, 4-hour and daily OHLC intervals with an OHLC crosshair, without connecting a wallet or trading account. - **Pro intervals and indicators** Add 5-minute and 15-minute views, MA20, EMA12, Bollinger Bands, RSI14 and MACD. - **Outcome overlays** Pro supports comparisons of up to 8 outcomes on a chart. - **Desktop alerts** Set thresholds for background checks at 60-second intervals and delivery through desktop notifications. - **CSV and preferences** Export timestamps, OHLC and the supplied proxy-volume field, and retain panel and alert settings locally. ## Workflows with PolyChart ### Inspect price structure Open the correct event, choose its outcome and select the candle interval before interpreting patterns. ### Compare outcomes Overlay related outcome histories on Pro and examine whether their patterns actually differ. ### Configure a notification Set the price threshold and enable browser notifications.

Install from the official Chrome listing. 2. Open a supported Polymarket event page. 3. Choose the exact outcome and position the floating panel. 4. Select an interval and any available indicators. 5. Enable notifications if using price alerts. The supplied volume is proxy volume and does not represent a complete traded-volume record. ## Useful links ### What to check - The volume series is a proxy, not complete exchange trade volume. - Alerts use desktop notifications and checks roughly every 60 seconds. - Historical candles are not executable quotes. - Pro validation depends on the provider’s external entitlement service. A closer look ## Ratings & reviews Editorial rating **3.5**/ 5 0 user reviews PredictionToolkit editorial ### Our take on PolyChart Editorial rating: 3.5/5. PolyChart is useful when price history needs to sit beside the market being read: the movable panel, defined interval tiers and exports support that task. Its volume is a proxy, and alerts depend on the browser, so neither feature supplies a complete venue feed or independent server monitoring. Based on documented features, setup and access terms.
