How to read it. Trend rules lose more trades than they win. A median below zero with a profit factor above 1 means a few large winners pay for many small losses. Measured on 3,163 liquid U.S. common stocks with next-open fills, updated 2026-10-23.

Frequently asked

Is this a market-data API?
No. We publish nightly research opinions: signals, regime, scores, and earnings CallCards. For raw prices, use free market tools. For daily, regime-aware calls with evidence attached, use LOPJLB. How it works → · Compare →
What powers the research?
Four proprietary models (direction, performance, fundamentals, market regime) plus three overlays (exhaustion, ATR trail, 60-day HiLo). Models are backtested out-of-sample. Methodology →
What are "strategies" and how are they backtested?
A strategy is a fixed entry/exit rule on a signal combo. We simulate equal-weight portfolios across the full universe since 2017 (Sharpe, drawdown, PF, win rate, equity curve). Failures never publish.
What is the "Best Combo" per stock?
Best Combo V5 is one pre-registered stable-evidence model, not a per-ticker recipe search. Five signal families vote bearish, neutral, or bullish; conflicting and missing evidence stays neutral. Smoothed evidence and two confirming closes drive next-open entries and exits. The signal itself determines how long to hold, with no target or forced holding period. Published point-in-time out-of-fold metrics include 20 bps round-trip costs; actions require at least 20 trades, positive expectancy and confidence, controlled drawdown, and limited single-trade concentration. Otherwise it abstains.
Is this financial advice?
No. Independent research only. You size, execute, and manage risk. We do not manage money or personalize advice.
Do you offer a free trial?
Yes. Checkout without a current subscription starts a 7-day trial (Essential, Research, or Pro). No charge until day 8. Cancel anytime during the trial from Settings → Manage billing (or Pricing) and pay nothing. Referred by a member? You get 37 days instead of 7. Returning customers who canceled can get another trial.
What is research chat and what are the limits?
Desk Q&A at /chat (and CLI lopjlb ask) grounded on the same data as the research blog posts: signals, fundamentals, CallCards, regime, and calendars. Caps are per UTC day: guest 1 · signed-in free / Essential / Research 3 · Pro 10 · Enterprise unlimited. Enterprise also gets MCP ask_research_desk. Not investment advice.
Can I call the API from my own LLM agent?
Yes. Free: regime, search, thin signal card, detail, intel, research chat/ask (30/min · 500/day on ticker routes). Full packs and browser intraday need Pro login or an Enterprise key. Keys also unlock universe, MCP (incl. ask_research_desk), and export. See /developers.
What is the difference between Research UI CSV and Enterprise export?
Research CSV is the current screener filter in the desktop browser. Enterprise export is the full latest-signal book via API/CLI.
Is there a mobile app?
Yes. The Capacitor iOS/Android app ships Pro and Enterprise via App Store IAP (complete desk only). Essential and Research are web/Stripe until StoreKit SKUs exist. You can also install the PWA from the browser.
Can I cancel anytime?
Yes. Paid desk plans and Enterprise are month-to-month (or annual at -35%). Cancel anytime from Settings → Manage billing (opens Stripe Customer Portal), or from the Manage billing button on Pricing. No lock-in.
