Coastline
A local-first AI-assisted trading risk desk and paper-trading lab. Designed for analytics, recommendations, risk checks, no-trade decisions, and auditable simulation before any future broker automation.
What it is
Coastline is a desk-style application for individual traders who want a serious risk and research workflow without sending their data to a third-party cloud. It supports analytics, AI-assisted recommendations, structured risk checks, explicit no-trade decisions, and a paper-trading lab for evaluating ideas before any real-money execution.
Why local-first
Trading data, journal entries, and strategy notes are sensitive. Coastline runs on your machine, stores its data on your machine, and treats network access as opt-in for specific features rather than a default assumption.
Highlights
- Risk checks before entries. Position sizing, exposure ceilings, and rule violations surfaced before a trade is committed, even on paper.
- Auditable simulation. Every paper trade and decision is logged with the assumptions and signals that drove it.
- No broker automation in v1. Coastline is explicitly a research and decision tool first; broker integration, if added, will be opt-in and isolated.
- Honest AI surfaces. Recommendations come with their reasoning and their confidence; the user is always the trader of record.
