Trading pair overview

Bitcoin (BTC) is a digital currency transferred over a peer-to-peer network. Transactions are recorded on a public blockchain and confirmed through mining. Wallets use private keys to authorize transfers. This pair quotes BTC in EUR.

Read the trading pair

BTC-EUR prices one unit of BTC in EUR. A price in a USD pair and a price in an ETH pair use different units. Keep this exact pair in the data query, strategy and test.

The pair catalog records flat-file data presence and the date the pair was observed. Inspect dated price rows to choose a test window.

Inspect BTC-EUR daily price rows

This query reads one stated month from the daily dataset. Change the dates to your proposed test window, then inspect the first and last returned dates and daily closes. The query is an inspection example; opening this page does not submit it.

SELECT symbol, date, openingPrice, highestPrice, lowestPrice, closingPrice, tradingVolume
FROM lake.crypto_daily
WHERE symbol = 'BTC-EUR'
  AND date >= TIMESTAMP '2024-01-01'
  AND date < TIMESTAMP '2024-02-01'
ORDER BY date
LIMIT 31;

Test explicit strategy rules

Choose the pair, observation interval, starting capital, entry rules and exit rules before comparing historical results. Report the tested window and modeled fees with the result.
