सोप्या भाषेतील अर्थ
A screener applies explicit conditions to stored/source-backed fields for one exchange or chosen universe. A match describes available inputs at that time, not future performance.
Where it appears #
Use Screener Builder, presets, Scan Center, saved/public screens, result metric picker, alerts and backtests.
Step-by-step workflow #
1. Select exchange and universe. 2. Add conditions and indicator overrides. 3. Review units and unavailable behavior. 4. Run. 5. Add optional result columns. 6. Open matches for evidence. 7. Save only the exact rule you reviewed.
Worked example #
A rule RSI(14) < 30 and volume > 1,000,000 returns only rows with both computed inputs. A listing with missing volume is unavailable and must not pass as volume 0.
How to interpret the result #
More matches mean more rows satisfy the rule, not a stronger signal. Positive/negative fields retain their metric meaning. Zero can be genuine; — means not evaluated or unavailable.
Limitations and common mistakes #
Look-ahead bias, stale data, survivorship bias, unlike currencies and mismatched indicator conventions can mislead. Backtests are historical observations, not predictive accuracy.
Market-specific differences #
Exchange universes, currencies, sessions, price scales, filings and technical coverage differ. Never let an empty international universe fall back to NSE symbols.
