Where does the price data come from?

Prices are fetched directly from each exchange’s public API. Coinbase, Kraken, Binance, Bitfinex, Bitstamp, KuCoin, Poloniex, OKX, HitBTC, and Bitpanda are all supported. There is no third-party aggregator in between.

What is arbitrage potential and how is it calculated?

Arbitrage potential is the price difference between the cheapest and most expensive exchange for the same coin and trading pair, expressed as a percentage. A higher spread means a larger theoretical gap, though real arbitrage also involves fees and execution speed.

Does the app make trading recommendations?

No. The trade signal gauge and volatility index are informational indicators derived from market data. Crypto Coin Check does not give investment advice. See the disclaimer below.
