ലളിതമായ അർത്ഥം
A combination scan joins two or more existing scan definitions into one transparent rule. XMarketRadar uses AND logic: every selected scan must match the same listing. It does not average scores, rank favourites or relax rules to force results.
Where it appears #
Open Screeners, then Combination Scans. The catalogue shows available scans and their rules; the selection panel shows the resulting flow and the combined condition sent to Screener Builder.
Step-by-step workflow #
1. Confirm exchange and intended universe. 2. Search the scan catalogue. 3. Read each scan’s full conditions. 4. Add two or more compatible scans. 5. Review the generated AND query. 6. Name the combination. 7. Open and run it in Screener. 8. Inspect the result columns and unavailable states before saving, exporting or backtesting.
Worked example #
Scan A is ‘RSI 14 < 35’; Scan B is ‘Relative Volume > 1.5’. If 40 listings match A, 25 match B and 8 match both, the combination returns 8—not 65. A listing with RSI 31 and relative volume 1.2 fails because both rules are required.
How to interpret the result #
More selected scans normally means fewer matches, not higher quality. Zero is a valid evaluated result when no row satisfies every condition. Unavailable means a universe or input could not be evaluated. Positive/negative values inside the component rules keep their own definitions.
Limitations and common mistakes #
Combining similar scans can duplicate the same idea without adding independent evidence. Conflicting conditions can make a result impossible. Historical overlap, small samples and survivorship bias remain. A memorable scan name does not turn descriptive rules into investment advice.
Market-specific differences #
All components run against the same selected exchange/universe. Different venues have different currencies, sessions, coverage and symbol populations, so counts are not directly comparable. Missing international coverage remains honest and is never substituted with another market.
