Elliott waves: compare trading-bar duration and calendar duration separately

Record both measurements

A movement can begin before a weekend and end after it. Its calendar duration includes the closure, while its trading-price bar count depends on the source session and interval. Write endpoint timestamps and the number of observed completed price bars separately so a reader can reproduce each measurement.

Define the counting convention

In an invented indexed dataset, two endpoints are at price bars 10 and 15. Their index difference is 5 intervals, while including both endpoint price bars gives 6 price bars. Neither convention should be silently mixed with the other. Define the duration as intervals between endpoint price bars if that is what the worksheet uses.

Keep market calendars with the source

A continuously traded instrument and an exchange instrument with closures need not have equal price bar counts over the same calendar dates. Check source coverage before diagnosing a missing row. A calendar gap can be expected, while a missing observation during an active session may be a separate data-quality issue.

Avoid a timing rule from a loose comparison

A duration resemblance can be recorded as an observation under a defined convention. It does not establish that the next wave must finish after the same number of hours or price bars. Keep structural requirements, timing descriptions and prospective forecasts in separate parts of the analysis.

Time proportions: bars and elapsed hours differ

Reuse the published teaching calendar: five one-hour bars per session on 5–8 January 2026,09:00–14:00 UTC. Window A contains 5 bars and spans 5 hours. Window B contains 20 bars over four sessions, but spans 77 clock hours including the gaps. Therefore N_B/N_A=20/5=4, while T_B/T_A=77/5=15.4.

The two ratios answer different questions. Keep bar interval, session calendar, cutoff and endpoints with each measurement. Do not draw overnight bars to make the counts match elapsed hours. These are invented observation windows, not proof of completed waves or a rule requiring the next correction to last four times as long.

Fibonacci time zones: a stated review-line convention

For this original diagram define t(k)=10+8k, with k chosen as 0,1,2,3,5,8,13. The base interval is 8 index units; the review lines lie at 10,18,26,34,50,74,114. This is an explicitly selected coordinate convention, not a claim that a product must draw exactly these defaults.

TradingView’s Fib Time Zone uses a base interval and vertical time lines; it does not set a price target. Fix the anchors, displayed coefficients and counting convention before examining later data. Bar indices are not automatically calendar dates. A line marks a place to review a scenario, not compulsory wave completion or a measured reversal probability.
