This was synthetic. The website carries no real market data. In the app, this is where the real symbol and year appear, plus a review of your last few dozen rounds.
| Step | What you do | What it prevents |
|---|---|---|
| Start | A random slice of history; you are not told the ticker or the year | Recognising the setting and recalling instead of judging |
| Step forward | Decide before each bar drops: buy, sell, or hold still | Peeking at the ending and letting it colour the call |
| Reveal | Only at the end: ticker, year, and what came next | "I knew it all along" |
| Post-round review | 13 tags such as chased, paper hands and round trip, judged per trade on ATR rules; behaviour, not profit | Grading yourself on one round's P&L |
| Item | Free | Local lifetime |

| Rounds per day | 15 rounds / day | Unlimited |
| Timeframes | Daily | All timeframes |
| Indicators | 3 basic indicators | All, adjustable |
