A formula is a reproducible map

Traditional, Fibonacci, Woodie, Camarilla, and other pivot formulas transform prior open, high, low, and close values into a central level and surrounding references. Formula choice, anchor timeframe, settlement treatment, and session data can all change the result.

The benefit is reproducibility: once the inputs and formula are fixed, another person can calculate the same levels. Reproducible does not mean predictive.

Fibonacci grids begin with two endpoints

A Fibonacci retracement grid divides the distance between two selected extremes using chosen ratios. The endpoints can come from a completed day, week, confirmed swing, or manual selection. Changing either endpoint moves every line.

Developing ranges can continue to expand, so their grid can move. Confirmed ranges are more stable but arrive later. A clear chart labels which state and timeframe are active.

Confluence is descriptive

When levels from several formulas or ranges cluster, a zone can summarize their proximity. But related formulas often reuse the same high, low, and close, so the lines are not independent observations.

Use a tolerance defined in ticks, points, percentage, or ATR, and report which levels created the cluster. Avoid implying that a larger count guarantees a stronger response.
