Charts blank or not updating in Match-Trader

What is causing it

Usually a browser-side problem such as a blocked request, a stale cached session or graphics acceleration, or genuinely limited history from the feed.

Why this happens

A web chart draws from data held in the page and streamed over a live connection. Anything that interrupts that connection, including extensions and privacy filters, leaves the chart with nothing new to draw even though the rest of the page looks healthy. Available history, by contrast, is set by the data the firm supplies.

The fix, step by step

1. Reload the page and give the chart time to fetch history again.
2. Switch instrument and timeframe and switch back to force a redraw.
3. Open the platform in a private window. If charts work there, the cause is a cached file, a stored session or an extension in your normal window.
4. Turn off ad blockers and privacy extensions for this address and reload, as they frequently block the live data connection.
5. Try a different browser to establish whether the problem is local.
6. If drawing looks corrupted rather than empty, toggle hardware or graphics acceleration in your browser settings and restart the browser.
7. If history is short on one instrument only, ask the firm how much history they supply for it.

How to confirm it is fixed

Candles form in real time and scrolling back loads older bars without gaps across the period you trade.

Stopping it happening again

Use a clean browser profile for trading, with no extensions and no automatic cleaning tools pointed at the platform's address.
