Nishi Finance
★ v0.1.3 · LIVE · sovereign · integer-exact · honest by construction

A trading, tax & grants stack, built from the silicon up.

24 sovereign organs, ~300 gate-verified tests, zero external dependencies — no gcc, no Python, no cloud. Real market data flows the whole pipeline, and the engine refuses to hide a loss or claim an edge it cannot defend.

Sim-first · live execution gated until an edge is proven out-of-sample

The pipeline

Analyze, prove, size — end to end

Every stage is sovereign, integer-exact, and gate-verified. Nothing ships on an unproven edge.

Screen the universe

A microcap funnel composes management-stewardship grading, the Altman-Z distress signal, and a liquidity wall — turning 1000 names into the few worth trading.

Backtest — the truth engine

Point-in-time, no look-ahead, real slippage. It reports expectancy, Sharpe, Sortino and max-drawdown — and honestly reports losses. Deflated-Sharpe and PBO kill overfit edges.

Size and diversify

Fractional-Kelly and 1%-risk sizing, a max-drawdown circuit breaker, and mean-variance portfolio construction so no single loss can sink the account.

Measured, never claimed

Measured against two honest bars

760 permille vs backtesting libraries (Backtrader, Zipline, pyfolio) on core quant logic — but against the real giants (Bloomberg, live trading platforms, consumer fintech) the honest number is 343 permille. We are a niche, not a titan. Liar-kill armed: 0.

A defensible niche — 5 real edges

Sovereign and zero-dependency, integer-deterministic and bit-reproducible, tax-integrated, honest-by-construction, with genuine overfit rigor (deflated-Sharpe + PBO). Narrow, structural, real — not a claim to be a better platform.

Behind where it counts — 10 ways

Against Bloomberg and the mature trading bots we are behind on real-time data, data breadth, live execution, broker integrations, news, analytics depth, community and scale — the core of real-world value, and we are behind on all of it.

A prototype, not a platform

Zero users, zero AUM, one symbol on a demo key, no live track record. We do not even address consumer finance (the Rocket Money category). The road to real: data breadth, then a proven edge, then gated live.

Get it raw, legally, politely

Most gated data is free at the source

Aggregators charge for convenience, not exclusive access. We go to the primary source — respecting robots, rate limits and terms — and never circumvent a paywall.

Free-raw (public domain)

SEC EDGAR fundamentals, proven live: Apple total assets 371 billion dollars, pulled raw over our own TLS — no key, no payment.

Free-tier (keyed)

Alpha Vantage OHLCV flows into the whole pipeline over the sovereign fetcher. Config-driven: drop in a free key to unlock the full universe.

The paid wall

Where data is genuinely licensed (real-time tape, tick depth), the system says license it — or take a free alternative. It will not help circumvent.

Version roadmap

v0.1 today, then v1.0 a real edge, then v2.0 live

Versions track REAL milestones, not dates. Each capability climb is a minor bump; the majors are earned and measured, never asserted.

v0.1 — built & sim-proven (now)

The full stack: 24 organs, ~300 gate-verified tests, all four asset classes, the census at 760 permille, now LIVE on the public edge. Where we stand today.

v1.0 — a validated edge

A real edge found across a universe and cleared by the deflated-Sharpe, PBO and out-of-sample gates. Unlocked the moment a data key opens real breadth.

v2.0 — live execution

Real capital via a broker adapter, gated behind a proven v1.0 edge. Never before the edge holds — that is the whole discipline.

The honest bottom line

Real and honest — and not yet done

The machinery is built and proven on live data. Reaching a million dollars is a disciplined process, not a promise: it needs data breadth, then a validated edge, then gated live execution — in that order.
