Chart Pattern Screener for NSE Stocks Pattern ScreenerThe Chart Pattern Scanner answers "what shapes are on this stock". This one asks the opposite question — pick a single pattern and it checks every NSE stock we hold daily history for, then shows you the ones where that shape finished most recently, newest first. Every match is drawn on its own chart with the points marked and scored on how closely it fits the textbook, and any other pattern completing on the same stock is listed with it.
How to use the Pattern Screener
- Pick one patternOne shape per screen — harmonic, reversal, wedge, triangle or trendline. Screening for one at a time is what makes the results comparable across stocks.
- Choose how recentHow many sessions back a pattern may have completed and still count as recent. A tight window shows only what finished in the last few days.
- Set the history depthHow many sessions of each stock to read. More history finds larger shapes; less keeps the screen focused on the current move.
- Tune quality and swing sizeQuality is how closely a match sits to the textbook shape. Swing size decides what counts as a turn — larger ignores small wiggles.
- Read the resultsMatches are ordered by how recently they completed. Each card carries the chart, the dates, the fit score and any other pattern found on that stock.
Frequently asked questions
How is this different from the Chart Pattern Scanner?
The Scanner takes one stock and finds every pattern on it. The Screener takes one pattern and finds every stock showing it. Same detection engine, opposite question.
Which stocks does it check?
Every symbol in our stored NSE daily price history that has enough sessions to analyse — there is no list to pick from, because the point is to sweep all of them.
Why only one pattern at a time?
Because the results are a ranking. Mixing several shapes in one list means comparing a Gartley against a triangle, which tells you nothing about either. One pattern per screen keeps every row directly comparable.
What does "completed 3 sessions ago" mean?
The pattern's final point printed three trading sessions before the latest one we hold. A swing pivot is only confirmed once enough later bars have proved it was a turn, so the newest sessions never carry pattern points — that lag is what makes a reported pattern settled rather than provisional.
Does a recent pattern mean the stock will move?
No. This tool reports geometry that has already formed in past prices and nothing else. It gives no targets, no entries and no ratings, and it makes no claim about what a price does next. Patterns fail often. It is a study and research aid, not a recommendation, not a tip service, and not investment advice.
What do bullish and bearish mean here?
They are how technical-analysis literature classifies the shape itself — an inverse head and shoulders is described as a bullish formation, a rising wedge as a bearish one. It is a label attached to the geometry, not a view on the stock and not a forecast.
