FAQ
What is RSI(14) cross 70?
RSI(14) cross 70 is a short-side study. Fires when the 14-period RSI crosses below 70 — leaving the overbought zone.
Which names are firing it?
Among mega-caps in the last 5 daily bars: AMD.
What is the sample?
Hit rates use the same rank engine as /t/spy on a fixed sample (SPY, SPX, QQQ, IWM, AAPL, MSFT, NVDA, TSLA). 8 of those names have a measurable history for this rule. Windows are 5 days, 1 month and 3 months on daily bars. Last bar in sample: 2026-10-12. Method: /methodology. Caveats: /help.
What does RSI(14) cross 70 measure?
Fires on the daily bar the 14-period RSI crosses below 70 (prior bar at or above 70, this bar below). Catalog reading: leaving the conventional overbought zone. Underlying math: see How it works on this page. Catalog line: Fires when the 14-period RSI crosses below 70 — leaving the overbought zone.
What does a firing mean?
A firing is the daily bar where this rule’s condition becomes true (a cross or a flip). It is a study event, not a recommendation to buy or sell. Forward windows on this site are close-to-close with no costs. Study side is short-side (SHORT). A positive forward return is a decline in the close after the print (side-adjusted) — a scoring convention, not a recommendation to sell short. Method: /methodology.
Why can the sample be small?
Hit rates need enough dated prints with a completed forward window. A row with fewer than 10 firings is anecdote, not evidence — the same caveat as /help. Slow rules (especially 50/200 SMA crosses) often have single-digit counts on a two-year tape. We do not invent a hit rate when the count is missing. Names in this sample with a measurable history include TSLA · MSFT · AAPL · NVDA.
How it works
Wilder RSI on the daily close with period 14. Up-moves and down-moves use an exponential average with alpha = 1/14 (min_periods=14, adjust=False). RS is average gain divided by average loss. RSI = 100 − 100 / (1 + RS). A firing is the daily bar where RSI crosses a fixed threshold — not the bar it first enters the zone.
Fires on the daily bar the 14-period RSI crosses below 70 (prior bar at or above 70, this bar below). Catalog reading: leaving the conventional overbought zone.

How to read it
Study side is short-side (labeled SHORT on firing chips). A positive forward return on this page is a decline in the close after the print (side-adjusted). That is how the event is scored — not a recommendation to sell short. Textbook RSI treats 30 / 70 as conventional oversold / overbought lines. This page records the exit of those zones (a cross), which is a weaker claim than “the name is oversold.” Read the print as a dated study event on daily bars, then look at the hit-rate table for how often similar events were followed by a positive side-adjusted move — not as a forecast for the next bar.
Scoring on this site is shared across every rule (5-day / 1-month / 3-month close-to-close windows, side-adjusted). See How it is scored here below. Names in the tracked sample with a measurable history include TSLA · MSFT · AAPL · NVDA. Those figures are the same rows as the hit-rate table below — not a second ranking. Historical hit rates, not a prediction / not trade advice.
When it fails
- RSI can stay under 30 (or over 70) for a long decline (or advance); repeated zone exits are not a reversal.
- Thresholds 30 and 70 are conventions. This site does not search for a “better” cutoff.
- Wilder smoothing is slower than a simple average — late prints in a fast move are expected.
- Past ≠ future. A historical hit rate is not a prediction and not investment advice.
- No costs modeled. Forward returns are close-to-close with no commissions, slippage or borrow.
- Small samples. A row with fewer than 10 firings is anecdote, not evidence.
- Overlap bias. Clustered prints can credit the same later move more than once.
Same caveats as the rest of the site: /methodology · /help.
How it is scored here
On this site every rule is scored the same way: run it over about two years of daily bars, record each firing, and measure what the name did 5 days, 1 month and 3 months later. Sell signals are measured as shorts, so a positive return is a profitable short (side-adjusted). The composite score is 0.6 × average return + 0.4 × (win rate − 50), with longer horizons weighted more. Nothing here is a forecast.

Honest caveats
- Past ≠ future. Everything here is a historical measurement on daily bars, not a prediction and not investment advice.
- No costs modeled. Forward returns are close-to-close with no commissions, slippage or borrow.
- Overlap bias. Signals that fire in clusters get credit for the same move more than once.
- Small samples. A row with fewer than 10 firings is anecdote, not evidence.
