The chart will not load
The Arena draws its chart in your browser, so a blocked script or a very old browser will show an empty panel. Refresh first. If it persists, try a current version of Chrome, Edge, Firefox or Safari, and check whether an extension is blocking scripts on the page.
I want to start over
Press End session to close the current one and get your scorecard, then open the Arena again — every session is a fresh, unseen chart. There is no penalty for ending a session early, and no reason to sit through a chart you are not learning anything from.
My session ended unexpectedly
Closing the tab or losing connection mid-session leaves it unfinished. Unfinished sessions do not score and do not affect your streak or heatmap. Just start a new one.
Switching timeframe restarted my chart
That is intentional. A replay cannot be re-cut mid-session without showing you information you did not have at the time, so a timeframe change starts a fresh chart. Decide your timeframe before you start.
My session says it is not ranked
Trades are played in your browser and posted back when the session ends. If the posted trades do not line up with the chart they were played on, the session still saves and still coaches you, but it does not count towards the leaderboard. Normal trading will not trigger this.
The Lab is hard to use on my phone
It works on a phone for reading and light practice, but the Arena is a chart-and-ticket workspace — a laptop or desktop is genuinely a better experience, and it is what we would recommend for real practice.
An indicator has a padlock on it
VWAP, RSI, MACD and ADX are Lab Pro features. EMA 9, EMA 20 and SMA 50 are available on every account.
