METHODOLOGY
Data Sources and Methodology
Signal Letter organizes scattered market snapshots and public sources into reviewable market signals. It is not designed to present certainty or prediction.
Directions, levels, and ticker categories are for observation and research discussion only, not trading instructions.
Market Snapshots
Each issue records the relevant session's price, percentage move, volume, turnover, range position, and watchlist size. A-share and U.S. market sessions publish at different times, so English issue timestamps are shown in UTC.
If ticker data is missing, delayed, or abnormal, the data-check area shows the number of gaps instead of presenting incomplete data as a firm conclusion.
Public Sources
When an issue references news, filings, earnings reports, investor-relations material, or media coverage, it preserves the source name and link where possible. The homepage shows a small source digest; the ticker view keeps the fuller source trail.
Views without a direct public source are treated as market-structure observations rather than news catalysts. External links are provided for verification and do not imply endorsement.
How Focus Tickers Are Selected
Focus tickers usually come from a combination of trading activity, price position, short-term relative strength, sector linkage, news catalysts, and risk signals. Bullish, watch, avoid, and bearish labels describe review angles, not buy or sell instructions.
Leveraged ETFs, high-volatility stocks, premarket data, and overnight data are handled more cautiously because liquidity, spreads, and drawdown speed may differ materially from regular-session trading.
Risk Boundaries
Key levels are used to explain where an issue's view may fail or require reassessment. Market prices may change quickly, and past performance, intraday signals, and public reports do not guarantee future results.
Any investment decision should be based on personal risk tolerance, capital planning, and appropriate professional advice.
