Active and fit
Check market, ticker, currency and if the chart is adjusted for splits and dividends. Two classes of shares or listings may differ. The logarithmic scale compares percentage changes and is useful over long periods.
Temporality
The daily candle summarizes the opening, high, low and close of each session. Use weekly for long-term structure and daily for detail; Intraday frames contain more noise. Analyze from highest to lowest.
Example
A deep 15-minute pullback may be an irrelevant swing within an intact weekly trend.
Minimum reading
Start with trend, supports/resistances and volume. Add a flag only if it answers a question. Five derived price oscillators are not five independent tests.
Reproducible template
Save colors, scale, sessions and frames. Mark date of results and gaps. Make dated captures to avoid retrospectively redrawing levels that were not visible.
