Daily Close Methodology

The daily close is the price reference traders use to mark the end of a trading period and reset market bias. It serves as a reference point for comparing current price action against the previous period's closing value.

DailyClose displays current price, previous close values from our data provider, and countdowns to common close times. These values are reference data, not signals, recommendations, or predictions.

Crypto markets trade 24 hours a day, 7 days a week, so they do not have a traditional exchange close. Traders commonly use the 00:00 UTC candle boundary as the crypto daily close reference.

UTC is used because it avoids exchange and local-time bias. It gives Bitcoin, Ethereum, Solana, Chainlink, and other crypto assets a shared daily reference point across global markets.

In the current Phase 1 implementation, page cards show the previous close value returned by the market data provider. A later data phase should verify true UTC candle-close history before DailyClose labels those values as calculated UTC candle closes.

For traditional markets like stocks, ETFs, and some macro proxies, the daily close depends on market hours, exchange rules, holidays, and data-provider conventions. US equity sessions commonly close at 16:00 Eastern Time.

These markets generally operate on weekdays and may be closed for market holidays. After-hours price movement can differ from the regular-session close, so DailyClose treats provider previous close values as reference data.

Different assets have different close definitions. The current app uses provider quote fields for previous close display; a later data phase should verify asset-specific close and settlement rules before using stricter language.

The current DailyClose cards use current price and previous close fields returned by the configured market data provider. For many assets this is a useful reference, but it may not always match a manually calculated UTC candle close, futures settlement, exchange close, or adjusted historical close.

Phase 1 improves search clarity without changing the data provider. A future phase should verify true candle and session close data before adding historical close tables or stronger claims.

A small number of macro and commodity assets are not available on our current data plan tier. To keep the page useful, those assets show a disclosed ETF proxy instead of the underlying index or futures contract. The card on those pages always carries a visible caveat label.

• Dollar Index (DXY): shown via the UUP ETF (Invesco DB US Dollar Index Bullish Fund). UUP tracks DXY direction but trades at a different absolute price level. The DXY index quote itself is not available on our current data plan.
• Crude Oil (WTI): shown via the USO ETF (United States Oil Fund). USO holds front-month WTI futures and has known tracking error vs spot WTI. The WTI futures contract is not available on our current data plan.
• S&P 500: shown via the SPY ETF, which is the most widely tracked S&P 500 vehicle but is not the index itself.

The 10-Year Treasury yield is now sourced from a dedicated Treasury rates feed and reflects the actual yield, not an ETF proxy.

Session states are descriptive classifications based on the current price relative to the previous daily close. These states are calculated using a threshold-based system:

Session states are descriptive only and do not imply future price direction, trading recommendations, or market predictions.
