What 24/7 actually changes
No daily open means "above the open is premium" needs a definition you choose rather than one the exchange gives you. No weekend gap means gap-fill strategies have nothing to fill. And a "daily high" depends entirely on where you cut the day, which for a market with no close is a convention rather than a fact.
None of that makes crypto untestable — it makes the definitions your responsibility. Decide where your day starts before you run the test, write it down, and keep it fixed. That single discipline is the difference between a crypto backtest and a set of impressions.
Ethereum's own character
ETH is correlated with Bitcoin and typically more volatile, with its own flow around network events and its own periods of decoupling. Volatility clusters hard: quiet stretches and violent stretches, with the transitions arriving faster than in most traditional markets.
That clustering is why an ATR-adaptive stop like the Chandelier Exit or a Supertrend is worth testing here specifically — a fixed stop that's correct during a quiet week is nowhere near correct during a loud one.
Running the test
Open ETHUSD and step forward candle by candle. Everything we hold — mid-2022 onward — is open from the first chart, which for an asset with regimes this distinct is where a strategy is genuinely tested rather than rehearsed. The meter is candles stepped: 10,000 free sample first, or unlimited at $14.99 a month.
Frequently asked questions
Can I backtest Ethereum for free?
CRTLAB is free to try. You get ETHUSD on everything we hold, with every tool the product has, for your first 10,000 candles of replay — roughly two hours of stepping through a chart, no card needed. After the sample, unlimited replay is $14.99 a month, cancel any time. The archive runs from mid-2022, which is genuinely all the ETH data we have — not a plan limit.
How do I handle the missing daily open in crypto?
Pick a convention and fix it before the test — UTC midnight and the New York session open are the two common choices. What matters is that it doesn't change mid-backtest, because every level derived from it moves when it does.
Does Ethereum data include weekends?
Yes. It trades continuously, so the replay does too — which makes it a useful control against markets that gap, if you're testing whether a strategy depends on the gap.
