Pick a username and password. New username creates an account; existing one logs in. Saved on this device as a session token.

Pick a level — each one bounds the chart to a specific skill. All levels stay open; the "Goal" line is what success looks like.

Tune the lookback and extreme thresholds. Lower timeframes typically want a longer N (e.g. 240 for 1m intraday) so the EMA isn't dominated by a single spike.
