Pivot Point Calculator

Yesterday's high, low and close give you today's ladder. Five formulas, because the one people mean by 'pivot points' depends on who they learned them from.

This is a calculator, not advice. It works only on the numbers you type in — it has no market data and no opinion on what you are trading. Nothing here is a recommendation to open, close or size a position, and technical analysis describes probabilities rather than outcomes. The levels are arithmetic on one completed period, not a view on what price does around them.

Levels are only half the picture

A pivot ladder tells you which prices are marked; it cannot tell you what the chart has been doing around them. Chart AI reads a photo of any chart and describes the trend, the levels price has actually respected, the volatility and the volume — and keeps each analysis in a history.

Where the idea comes from

Pivot points predate charting software. Floor traders needed a handful of prices they could work out on paper before the open and carry in their heads all day, so they took the previous session's high, low and close, averaged them, and reflected that average through the extremes of the range to get levels above and below. The result is a fixed ladder for the coming session that never needs recalculating.

The classic formula is still the plainest statement of it: the pivot is (H + L + C) ÷ 3, the first resistance is 2P − L, and the first support is 2P − H. Everything above R1 and below S1 is the same reflection applied again, one range further out.

The five formulas, and what makes them differ

FormulaPivotLevelsDistinguishing idea
Classic(H+L+C)/33 each sideThe original; reflects the pivot through the range
Fibonacci(H+L+C)/33 each sideLevels at 38.2%, 61.8% and 100% of the range
Camarilla(H+L+C)/34 each sideMeasured from the close, so the inner pair sit tight to it
Woodie(H+L+2C)/43 each sideWeights the close double, pulling the pivot toward it
DeMarkDepends on open vs close1 each sideTreats up-closing and down-closing periods differently

They will not agree, and they are not supposed to. Camarilla's R1 and S1 will sit far closer to price than Classic's, because they are a twelfth of the range from the close rather than a reflection of the whole thing. Woodie's pivot shifts toward wherever the period finished. Picking one and staying with it is more useful than comparing them, since half of what makes a level matter is that other people have it marked too.

What a level is, and what it is not

A pivot level is a price computed from arithmetic on one previous period. Nothing about it guarantees anything — it is not support until price has actually stopped there, and a great many sessions run straight through several levels without pausing. What the ladder does give you is a set of marks made in advance, which is a genuinely different thing from drawing a line after the fact on a chart you have already seen move.

The most common misuse is treating the number of levels crossed as a measure of how far a move can go. R3 is not a target; it is simply where the third reflection lands. On a quiet day price may never reach R1, and on a day with news the whole ladder can be irrelevant by the first hour.

Questions

Which period's high, low and close do I use?

The one before the period you are trading. Day traders use yesterday's session and keep the levels for today; a weekly pivot uses last week's range. The important part is that the numbers all come from the same completed period — mixing a daily high with a weekly close produces levels that mean nothing.

Which formula should I use?

They answer slightly different questions. Classic is the original floor-trader version and the most widely watched, which matters if you care that other people are looking at the same prices. Fibonacci spaces the levels by ratio rather than by reflection. Camarilla measures from the close and puts its inner levels very close to it. Woodie weights the close double. DeMark gives one level either side instead of three. None is more correct than the others — they are different conventions, not competing measurements.

Why does DeMark ask for the open?

Because it uses a different equation depending on whether the period closed above, below or level with its open — the idea being that a period that closed down should be measured differently from one that closed up. That is also why it produces one support and one resistance rather than a full ladder.

Do pivot points work in 24-hour markets?

They can be calculated, but the period boundary becomes an arbitrary choice. Forex and crypto never close, so "yesterday's high" depends entirely on where you put the daily cut — 00:00 UTC, New York close, or your broker's server time all give different numbers. On markets with a real opening bell the boundary is a fact; without one, everyone is using a slightly different set of levels, which is exactly the property that makes pivots interesting in the first place.

Are the levels updated during the day?

No, and that is the point of them. Pivots are worked out once from the last completed period and stay fixed for the whole of the next one, which makes them a set of prices you can mark in advance rather than a line that moves as you watch it.
