Build with B4

Describe an indicator in plain language and let your AI coding assistant build it with the B4 NT8 skill library and the public B4 Signal API.

Specification first, then code
Every value an adjustable setting
Compile and verify before it reaches a chart

Ask B4

An assistant that explains technical-analysis concepts, troubleshoots indicators and reads the data you authorize, with timestamps and missing-data warnings instead of guesses.

Explains your own indicators and settings
Flags stale or unavailable data
Never reveals B4 proprietary logic

Test with B4

Reproducible historical research on your own indicator ideas: out-of-sample checks, costs and slippage, parameter sensitivity and overfitting warnings.

Simulation and research only
No strategy ever activates itself

Build with B4 · available now

From an idea to a verified indicator.

Works with Claude Code and compatible AI coding tools on your own computer. You keep your code; B4 never needs to see it.

Load the skill libraryDownload the B4 NT8 skill library and copy the skills into %USERPROFILE%\.claude\skills\.

Describe your ideaFor example: "Build a NinjaTrader 8 indicator that marks a failed breakout of the prior N-bar high, with N and the volume threshold as settings, and publish it through the B4 Signal API."

Start from a demoAsk the assistant to base it on a demo indicator. Every signal-affecting value becomes an adjustable setting.

Verify before you tradeThe build-verification skill compiles, checks and reports honestly. Install only when flat, following the safe-deployment skill.

AI-generated code is your own work and your responsibility. Test it in simulation first. B4 does not review or support user-built indicators unless they are submitted and accepted into the official repository.

Intellectual property protection

AI that extends B4 without exposing it.

B4 Indicator AI is built on public interfaces only. Protection does not rely on telling an AI to keep a secret: protected information is never made available to it in the first place.

Never accessible

B4 Algo source code, calculations, formulas and algorithms
B4 confirmation criteria, gates, weights and decision logic
Internal signal-generation rules and implementation details
Private DLL internals and protected development source
Internal research records, training labels and confidential documentation
Reconstruction of any of the above through repeated queries or collected outputs

What AI can work with

The public B4 Signal API contract and the official repository
Your own indicators and your own NinjaScript code
Public NinjaTrader 8 documentation and APIs
General technical-analysis concepts and education
Data you explicitly authorize, and only outputs B4 approves for customer use

Deny by default. Every AI tool, data field and integration endpoint must be on the B4 Public Interface Allowlist before it is reachable. Unknown or new fields stay blocked until reviewed. The boundary is enforced on B4's side, every request is checked, bulk extraction is limited, and any confirmed leak blocks a release.

B4 Indicator MCP · in development

A safe way for AI clients to use B4 Indicators.

The Model Context Protocol lets compatible AI clients discover and use approved tools. The public B4 Indicator MCP server is in development and is not available yet. It will cover public material only.

MCP access never grants trading authority. Research and simulation stay separate from live execution, and nothing places orders on its own.

Roadmap

Built in the open, released when verified.

A planning outline, not a promise of dates. Each step ships only after its checks pass.
