Chartdle

Chartdle strips the ticker off a real trading session and asks you to name what you are looking at. What you get is a proper candlestick chart with volume bars underneath, an intraday time axis running from the open to the close, and a price scale, and that is the entire brief. Six guesses, and the price level is the only number you start with.

1. Read the chart before you touch the search box. The absolute price level, the size of the intraday range and the shape of the volume profile narrow the field enormously on their own.
2. Type a ticker or a name into the guess box. The suggestion list is generous with plain-English names, so typing ES offers ES1! (S&P 500), YM1! (Dow Jones) and FESX1! (Euro Stoxx 50) rather than making you know the exact code.

Chart reading is one of those skills people claim in the abstract and rarely get tested on. Chartdle turns it into six falsifiable guesses a day, and the attribute grid is smart enough that being wrong is genuinely productive: a market cap arrow and a region tick will get you closer than a lucky ticker. The three separate boards mean you can pick the market you actually follow instead of being handed a random asset class, and the archive is open, so a bad day is not the end of the session. The footer is also refreshingly honest that this is a game and not investment advice.

The attribute grid is where the deduction lives. Guessing gold on the futures board returned Precious Metals in grey, Future in green with a tick, an $80B+ market cap in grey with a down arrow, roughly $30B a day of volume in grey with a down arrow, and Global in green. Guessing the S&P future straight after returned Equity Indices in grey, Future in green again, $50T+ with a down arrow, and USA in grey. Two guesses and the picture is already sharp: it trades globally, it is a future, and it is smaller in both cap and volume than either. The rules add a middle state, a yellow cell when your guess is in the right category but not the right instrument.

Futures

The default board, running everything from index futures to metals and energy, with market cap and daily volume figures scaled to match.

Stocks

Individual equities, reached from the Try other modes switch in the header. A separate daily puzzle with its own archive.

Forex

Currency pairs, again on their own daily rotation and their own archive.

Archive

The calendar icon opens a grid of dated puzzles for each mode. The dates follow trading days rather than calendar days, so weekends are simply absent from the list.

• Spend your first guess on something huge and something global. The market cap and volume arrows are absolute, not relative, so opening with a heavyweight like an index future guarantees a downward arrow that brackets everything smaller in one move.
• Region is the cheapest column to solve. It only has a handful of values, and getting Global versus USA settled early kills entire categories of instruments.
• The volume bars carry information the price does not. A closing spike into the last candle, or a dead middle of the session, tells you which exchange hours you are looking at, and that pairs with the time axis to place the instrument geographically.
