TradingView desktop won't open, hangs on the splash, shows a blank window, or fails after the launcher? Work through these 8 fixes in order. The first one (cache clear) resolves about 60% of cases in under 60 seconds.
"TradingView not loading" covers several distinct failure modes: the launcher doesn't appear at all, the splash screen hangs, the main window opens but is blank, charts load but show no data, or the app starts then immediately closes. Each has different root causes. The fixes below are ordered from most-common-and-cheapest to least-common-but-still-works. Try in sequence — stop when the app loads normally.
Win + R, paste %AppData%\TradingView, press Enter.Cache folder. Leave other folders alone.Your layouts, watchlists, and alerts are stored in your TradingView account on the cloud — they restore automatically. Only ephemeral cache data is removed.
Right-click the TradingView desktop icon → Run as administrator. If the app loads as admin but not as a normal user, the issue is file permissions in the install folder. Reinstall to a folder under your user profile (default: %LocalAppData%\Programs\TradingView) and the per-user permissions issue goes away.
Blank-screen and immediate-crash failures often trace to GPU driver issues. Update via:
If Norton, McAfee, Avast, or similar AV is installed: add an exclusion for %LocalAppData%\Programs\TradingView. Norton in particular has a history of false-positive flags on Electron-based apps (TradingView desktop is Electron-based).
TradingView needs outbound HTTPS (port 443) to:
*.tradingview.com*.tvc-mds.com (market data CDN)cdn.tradingview-cdn.com (static assets)Test by visiting tradingview.com in your browser. If the website loads but the desktop app doesn't, your firewall is selectively blocking the .exe — add an explicit allow rule in Windows Defender Firewall.
Some VPNs (especially free ones) inject SSL middleware that breaks TradingView's WebSocket connections. Disable the VPN, launch TradingView, confirm it works, then re-enable VPN and test. If it breaks again, your VPN is incompatible — use a different VPN or disable it during trading sessions.
If fixes 1–6 don't work:
%LocalAppData%\Programs\TradingView and %AppData%\TradingView.If none of the above work and you need to trade today, the web app at tradingview.com uses the same account and identical chart engine. Use it as a temporary fallback while you contact TradingView support at tradingview.com/support with your OS version, GPU model, and the symptoms.
Usually corrupted cache, antivirus blocking, firewall, GPU driver issue, or failed update. Cache clear fixes ~60% of cases; reinstall fixes another 30%.
Close app. Navigate to %AppData%\TradingView. Delete the Cache folder. Relaunch. Account data is in the cloud — won't be lost.
Embedded renderer failed to initialize. Update GPU drivers, then relaunch. Check for DLL-injecting third-party software (screen recorders, RGB controllers).
Sometimes — Norton, McAfee, Avast occasionally false-positive. Add %LocalAppData%\Programs\TradingView to exclusions.
Outbound HTTPS 443 to *.tradingview.com and *.tvc-mds.com. WebSocket on 443. No inbound ports.
