3 recommended custom software packages for Trading. Pay 50% upfront. Source code yours.
Why this combo
The decisions we made differently — and why they matter for trading specifically.
Survivorship-bias-free data, point-in-time fundamentals, realistic slippage + commission models. We test your code on T-bill data first to see if it leaks signal.
Position sizing, max drawdown halt, per-symbol exposure limits, kill-switch via webhook or Slack. Risk lives in the engine, not in a Notion doc.
Interactive Brokers, Alpaca, Tradier, Tradovate, Coinbase Advanced, Binance, Hyperliquid. Idempotent submission, reconciliation jobs, dead-letter queues. No silent fills.
Grafana dashboards for PnL, per-strategy attribution, slippage vs. modeled, latency p50/p99. You see what the algo sees.
Pinned data snapshots, deterministic random seeds, Docker-pinned runtimes. Your Q1 backtest still runs identically in Q4.
Equities, options, futures, crypto spot + perps. Per-asset cost models. Per-asset session calendars. We don't pretend everything is SPY.

Why Hayaiti
Most trading software starts as a notebook and dies as a Frankenstein. We rebuild it as actual software: typed, tested, observable, deployable. Our trading stack — backtest engines that walk-forward over thousands of symbols in seconds, broker integrations that don't lose fills, risk frameworks that survive contact with a real market open — is the same one we use for internal research papers. We are NOT a registered investment advisor; you own the strategy and the risk.

Shape of work
Internal research project: a cross-sectional momentum strategy on a liquid US equity universe. The deliverable was less the strategy itself and more the harness — a reproducible, parameter-swept backtest framework that could be used for the next 50 ideas.
Spec engagement built to set the bar — same playbook a real client gets. Real cases publish after launch with the client’s sign-off.
FAQ
Yes — mutual NDA, sent as PDF before the first technical call. We've signed plenty; we don't share your alpha with anyone, internally or externally.
No. We are NOT a registered investment advisor, broker-dealer, or CTA. We build the software that runs your strategy. You own the strategy, the trades, and the risk.
Equities/options: Interactive Brokers, Alpaca, Tradier, Tradovate. Crypto: Coinbase Advanced, Binance, Bybit, Hyperliquid, OKX. Each integration includes idempotent order submission and a reconciliation job.
Yes — that's a defined scope under the Trading Algorithm SKU. We need: strategy logic (paper or code), data assumptions, and your acceptable cost model. We'll deliver a notebook + walk-forward results.
We're honest: sub-millisecond HFT is not our wheelhouse. We're great for daily-to-intraday algos (5min+ bars). For HFT, we'll refer you out.
Start with an audit, or jump straight to pricing. Either way, you talk to engineers — not a sales funnel.
