ಸರಳ ಅರ್ಥ
Support and resistance are areas where prior price interaction is studied. They are better treated as zones with evidence and invalidation conditions than as guaranteed floors, ceilings or exact future turning points.
Learning objectives #
You should be able to build a zone from completed pivots, scale its width, distinguish a touch from a close beyond it, and document when a former resistance area is being observed as possible support without assuming role reversal.
Core concept #
Choose pivots without using bars that were not yet available at the decision time. XMarketRadar's Price Levels screen confirms a swing only after the configured number of later completed bars exists, then clusters observed pivot prices into bands no wider than the selected percentage. A breakout rule must separately say whether a wick, close or consecutive closes beyond a boundary count.
Method and conventions #
For the implemented calculator, choose 60 to 1,250 completed daily sessions, a 2-to-30-bar swing lookback, maximum band width from 0.1% to 10%, one to ten minimum pivot touches and no more than 40 returned zones. Bands use the median pivot price as centre. Their support, resistance or inside role and signed distance are measured against the latest persisted close.
Use it in XMarketRadar #
Open Support & Resistance Levels on Web or Flutter, confirm exchange and exact symbol, then set lookback, swing sensitivity, maximum width, minimum touches and display cap. Read evaluated bars, pivots, zones found versus returned, latest price date and source. For each band distinguish pivot touches from the weaker count of bars that merely overlapped it. Use chart drawings separately for your own annotations.
Worked example #
Illustrative only: three confirmed pivots at INR 94.80, 95.10 and 95.30 can form an INR 94.80–95.30 band centred on the median INR 95.10. If the latest persisted close is INR 93.50, the whole band is labelled resistance because it sits above that close. The label would change to inside if a later completed close lies within the band; neither label predicts the next bar.
How to interpret it #
Price inside a zone means the latest persisted close is within a historically formed band. Support means the whole band is below that close and resistance means it is above. PivotTouchCount is the primary reversal evidence; BarTouchCount only says a session range overlapped the band. More touches do not guarantee a stronger future response.
Limitations and common mistakes #
Hindsight makes zones look cleaner than they were in real time. Other mistakes are comparing runs with different settings, calling every overlapping bar a reversal, ignoring the displayed zones-found cap, selecting only successful levels, drawing through incompatible adjusted history, using excessive precision and treating a support/resistance role as a target.
Market-specific differences #
Tick size, price limits, auctions and typical volatility affect sensible zone width. Percentage or ATR scaling often supports comparison better than a fixed currency width across instruments.
Key takeaway #
Key takeaway: a support or resistance zone is a dated research construct with boundaries and an invalidation rule—not a barrier promised by the market.
Practice exercise #
Practice: construct one zone from information available at the third touch, hide later bars while defining it, then reveal the subsequent history and record the outcome without redrawing.
