Technical Analysis Calculators

Technical levels are arithmetic on prices that have already happened. A pivot point is a weighted average of yesterday's high, low and close; a Fibonacci retracement divides a completed swing into fixed proportions; an average true range is the mean of a set of daily ranges. None of them requires a view about what happens next, which is why each can be calculated exactly.

Every price on these pages comes from you. Nothing is fetched from an exchange or a data vendor, and no series is assumed. That makes the calculators slower to fill in than a charting package, and it makes them work for things a chart will not do — a session that has not printed yet, a hypothetical range, or a level you want to check against a broker's own figures rather than a third party's.

The indicators here are calculated exactly as they are conventionally defined, and each page states the definition it uses. That matters more than it sounds: charting packages differ on whether an average true range is a simple mean or Wilder's smoothing, and on whether a stochastic uses the fast or slow variant, so two platforms can show different numbers for the same series without either being wrong.

A level is a level. None of these calculations carries information about direction, and a price reaching a computed level says nothing about whether it will hold.
