How do I fix Chart blank, frozen or missing history in TradeLocker?

Usually the browser blocking or losing the chart's data connection, or limited history for that instrument from the firm's feed. Fix: 1. Reload the page and allow the chart time to request its data again. 2. Switch instrument and timeframe, then switch back, to force it to rebuild. 3. Test in a private window. If it works there, an extension, a cached file or a stored session is the cause. 4. Turn off ad blockers and privacy extensions for this address, then reload. 5. Try another browser to confirm whether the problem is local to yours. 6. If drawing is corrupted rather than absent, toggle hardware or graphics acceleration in browser settings and restart the browser. 7. If only one instrument has short history, ask the firm how much they supply for it.

Chart blank, frozen or missing history in TradeLocker

What is causing it

Usually the browser blocking or losing the chart's data connection, or limited history for that instrument from the firm's feed.

Why this happens

Charts in a browser platform depend on a live data connection and on files the browser is allowed to load. Privacy extensions and content blockers frequently interfere with exactly those connections, which leaves an empty chart on an otherwise working page. History length, by contrast, is determined by the data your firm provides.

The fix, step by step

Reload the page and allow the chart time to request its data again.
Switch instrument and timeframe, then switch back, to force it to rebuild.
Test in a private window. If it works there, an extension, a cached file or a stored session is the cause.
Turn off ad blockers and privacy extensions for this address, then reload.
Try another browser to confirm whether the problem is local to yours.
If drawing is corrupted rather than absent, toggle hardware or graphics acceleration in browser settings and restart the browser.
If only one instrument has short history, ask the firm how much they supply for it.
