Presets and rules
Each preset is the exact CleverScan rule this page runs on the latest published daily session. S&P 500 stocks: Stocks on the S&P 500 reference list captured with the published dataset.
| Preset | What it selects | Rule |
|---|---|---|
| RSI below 30 | RSI(14) is below 30. Values come from the latest published daily session (regular trading hours); the rule is evaluated once per published session, not tick by tick. Rows are ordered by rsi (14) (lowest first). | securityType = "Stock" and indexMembership contains "SP500" and (rsi14 < 30) |
| RSI above 70 | RSI(14), Wilder’s 14-session relative strength index, is above 70. Rows are ordered by rsi (14) (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (rsi14 > 70) |
| RSI above 50 | RSI(14) is above its 50 midpoint. Rows are ordered by rsi (14) (highest first). | securityType = "Stock" and indexMembership contains "SP500" and (rsi14 > 50) |
| RSI between 40 and 60 | RSI(14) is from 40 to 60 inclusive. Rows are ordered by rsi (14) (lowest first). | securityType = "Stock" and indexMembership contains "SP500" and (rsi14 >= 40 and rsi14 <= 60) |
| RSI under 30 above the 200-day | RSI(14) is below 30 while the close is above its 200-session simple moving average. Rows are ordered by rsi (14) (lowest first). | securityType = "Stock" and indexMembership contains "SP500" and (rsi14 < 30 and close > sma200) |
What this screen measures
RSI(14) measures the balance of smoothed gains and losses on a 0–100 scale. The default selects values below 30. The upper-extreme preset selects values above 70; midpoint and middle-range presets describe different momentum conditions.
Read the rule with a worked example
An RSI of 29.9 meets the below-30 rule; 30.0 does not. An RSI of 70.0 also fails the above-70 rule. In the middle-range preset, values from 40 through 60 are included. These hypothetical boundaries distinguish strict comparisons from inclusive ranges.
Choose the variant that matches the question
The below-30 uptrend variant adds close above SMA 200, separating weak recent momentum inside a longer-term rising context from weak momentum during a decline. RSI above 50 and RSI from 40 to 60 do not express the same selection question.
Review the chart behind a match
Inspect how long the oscillator has remained near an extreme and compare it with price swings. The RSI guide explains Wilder smoothing, a worked calculation and divergence. Divergence requires comparing distinct swings on a chart rather than one current oscillator value.
Keep the interpretation within the rule
An extreme can persist while price continues in its existing direction. Below 30 is not an instruction to buy and above 70 is not an instruction to sell. RSI also differs from a relative-strength ranking across stocks.
