FAQ
What is Supertrend flip up?
Supertrend flip up is a long-side study. Fires on the bar Supertrend flips from downtrend to uptrend.
Which names are firing it?
None of the mega-cap names fired this rule in the last 5 daily bars.
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). 0 of those names have a measurable history for this rule. Windows are 5 days, 1 month and 3 months on daily bars. Method: /methodology. Caveats: /help.
Why is today quiet for this study?
No study-grade (n≥10) mega-cap firings for Supertrend flip up in the last 5 daily bars. Historical context on tracked names and other rules that did fire are in the quiet-day study pack — not invented firings. See SPY technicals, /breadth, and /firing.
What does Supertrend flip up measure?
Fires on the bar Supertrend direction flips from −1 to +1 (downtrend to uptrend). Underlying math: see How it works on this page. Catalog line: Fires on the bar Supertrend flips from downtrend to uptrend.
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 long-side (LONG). A positive forward return is a rise in the close after the print — a scoring convention, not a recommendation to buy. 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. The hit-rate table on this page is empty when none of the tracked names have a measurable history for this rule.
How it works
Supertrend with ATR period 10 (Wilder, alpha = 1/10) and multiplier 3.0. Bands are built around the high-low midpoint. Direction is +1 (uptrend) or −1 (downtrend). The rule fires on the bar direction flips, not on every bar the trend remains in force.
Fires on the bar Supertrend direction flips from −1 to +1 (downtrend to uptrend).
Definition comes from the rank-rule catalog and the indicator defaults in this repo. Slug supertrend-flip-up is listed on /api/meta.
How to read it
Study side is long-side (labeled LONG on firing chips). A positive forward return on this page is a rise in the close after the print. That is how the event is scored — not a recommendation to buy. A flip is a change in the Supertrend state machine, not a prediction that the new state will persist. In a range the line can flip often; in a persistent trend it may not flip for months. The 10 / 3.0 parameters are the registry defaults.
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. The hit-rate table on this page lists the tracked sample when a measurable history exists. Historical hit rates, not a prediction / not trade advice.
When it fails
- Ranging markets flip direction often (whipsaw).
- ATR-based bands lag a volatility spike; the flip can be late.
- Period 10 and multiplier 3.0 are defaults, not optimized values.
- 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.
