The position of the dots sets the direction of the trailing stop.
The short answer
- What is the Parabolic SAR indicator (Parabolic SAR)?
- Parabolic SAR: dots that accelerate behind price until price breaks through them.
- When does Parabolic SAR get it wrong?
- In a range-bound market it flips repeatedly and the account bleeds commissions. See its reading now on platform symbols, at the latest daily close, in the "Reading now" table on this page. See its reading now →

A description of where the number sits against its thresholds. It is not an entry or exit signal.
Indicator limit
In a range-bound market it flips repeatedly and the account bleeds commissions.
Read it with
Average trend index: its flips in range-bound markets drop when you read it with ADX above 20 rather than alone.
Answers: does the market have a trend? Where does the stop go?
What it actually does
The Parabolic indicator draws a series of dots above or below price, moving closer step by step with an acceleration factor that grows as the trend extends. The idea is that the stop should chase the profit at a pace that quickens as the move matures, rather than staying fixed.
How it is read in practice
Dots below price mean an uptrend with a trailing stop beneath it. Dots above mean the opposite. The flip is the signal: the moment price breaks through the indicator's dots means the trend has reversed, by the tool's logic. It is an always-in-the-market exit-and-reverse system, not a selective entry indicator.
Its real value: managing the exit
Its best use is not generating signals but trailing the stop. You let the winner run and tighten the stop with each extension of the move. That answers a trader's hardest question: when do I exit a winning trade? It answers with a rule, not with emotion.
Hypothetical example
An uptrending position runs for three weeks. The dots start far below price, then close in with each new high until they almost touch it. The first real pullback breaks through them and the position closes with most of the profit kept, with no guesswork and no hesitation.
Where it errs and why
Disastrous in range-bound markets: it flips direction again and again and produces a string of small, consecutive losses. Because it is always in the market, it assumes the market is always trending, and that assumption is wrong half the time.
Read it with
Read it always with a trend strength indicator: switch it on above the trend threshold and off below it. Pair it with average true range to tune its acceleration factor to the asset's volatility. Use structural levels too, since a stop that creeps past a dense wall gets hit by mechanical noise.
Where to see it on the platform
The technical chart draws its dots right on the price, and the position size calculator turns the stop distance into a calculated share count.
