Tap the chart or use the Previous/Next candle buttons to inspect a candle. Mark a point; for a stroke or time window, mark endpoints in chronological order. Undo removes the last mark. Clear removes all current marks. Check my answer is enabled only when the required marks exist. The reference appears after submission.
Replay reveals the next candle only when you advance. Buy 10 and Sell 10 use virtual cash and holdings. You cannot overspend or sell units you do not own. Back removes later orders. Reset replay clears that virtual ledger. Settings → Clear all learning data also deletes notes and progress after confirmation.
No lessons after opening? Close and reopen the app; the content is bundled and no internet is required. A note not visible? Check the original lesson or Journal. Deleted data cannot be restored by the operator. A disagreement about a structural label? Read the task’s timeframe, supplied premises and convention before comparing interpretations.
