A Complete Intelligence Layer.
29-Driver Action Card + Grade
Scores 29 independent drivers simultaneously and produces one verdict: LONG, SHORT, or WAIT — with entry, stop, target, R:R, and a letter grade A+ to F reflecting conviction.
Institutional Conviction Score (ICS)
Proprietary 0–100 score tracking smart money conviction by testing whether dark pool print levels are holding as support or failing. No other retail API offers this.
Live Options Flow (Signa Intelligence)
Per-symbol live options flow: whale sweeps, blocks, unusual activity flags, premium, OI, and volume. Dark pool prints and congressional trade disclosures also available.
Broker Execution Routes
Connect Alpaca (paper or live), execute trades with Kelly Criterion sizing, sync live positions, and retrieve positions with Signa edge recommendations — all via API.
Wyckoff Phase Detection
All 7 Wyckoff phases detected with plain-English narrative. Auto-detects Spring, UTAD, and Last Point of Support. Returns a story, not just a label.
Elliott Wave + Fibonacci
Fail-closed OHLC-pivot counting. A 5-wave or ABC path is shown only when hard rules validate; otherwise the wave is unavailable and no path is drawn.
Multi-Symbol Scanner
Scan dozens of symbols simultaneously, ranked by signal strength. Bullish setups at the top, bearish at the bottom. Includes Signal Index (SSI) 0–100.
Natural Language API
POST a plain-English query like "best AI stock setups this week" — Claude extracts intent and symbols, then runs live signal analysis on each. Pro tier.
MCP Server + A2A Routing
Native MCP server for Claude Desktop, Cursor, and Windsurf. A2A agent routing protocol for multi-agent trading workflows. Industry first.
OHLCV History + Strategy Simulation
200+ days of candles with multi-source failover. Strategy simulation tools include Sharpe ratio, max drawdown, and win rate. Founding tier.

}The Only Trading API
Built for AI Agents.
Connect Claude Desktop, Cursor, or any MCP-compatible AI assistant directly to live signals, screener results, and full analysis. Ask "What are the best setups right now?" and get a real answer — not a hallucination.
The A2A routing protocol lets you build multi-agent trading workflows — route tasks to purpose-built Signa agents or register your own external agents into the network.
