How does a Chart Drill round work?

You see a real stretch of past candles for a coin. The next few candles are hidden. Decide whether the close after them will be higher, lower or about the same (inside the grey Flat band), then tap your call. The hidden candles are revealed and the result card shows what the chart looked like at the cutoff.

What is blind mode?

Blind mode hides the coin name, dates and prices until you answer, so you read only the shape of the chart. The price axis shows percent from the last close instead.

What is the Daily Set?

Five rounds chosen from the date, so everyone gets the same rounds on the same day. They mix daily, 4-hour and hourly charts and use blind mode.

Where does the data come from?

Prices, candles, market totals and coin information come from CoinGecko. Values are aggregated USD prices and can differ slightly from any single venue.

Do I need an account?

No. There are no accounts, purchases or subscriptions.

Can I trade or deposit money?

No. The app has no trading, no balances and no connection to exchanges or brokers. It is for learning to read charts.

How do I reset my progress?

Open Settings from the gear icon on Home. Under Data you can reset practice history, reset lesson progress or clear the market data cache.

A screen shows a connection message.

Market data needs an internet connection. Check your connection, then tap Try Again.
