StrategyIncluded in every plan · one key.

Overview

Run a scannable strategy across the S&P 500 and get the stocks that currently match its rules — no subjective chart reading, fully deterministic. Each match returns a BUY / SELL signal, a 0–100 strength score, the reasons each rule passed, and key numbers (breakout/entry price, a suggested stop, distance to that stop, the breakout volume ratio and distance from the 52-week high). Pass ?strategy=<id> (e.g. momentum_breakout or triple_rsi); omit it to run every scannable strategy. Symbols with no data are reported under `skipped`.

// Scanners with an objective stop (e.g. momentum_breakout) also populate
// stopLoss / riskPercent; strategies with a condition-based exit leave the
// price levels null rather than invent them. Fields are identical across every
// scannable strategy — only the values differ.
