About Tradewink
An AI trading assistant built to give individual traders the same quality of analysis and automation that institutional desks have — without custody, without complexity.
Built by Kavy Rattana
Tradewink was built and is maintained by Kavy Rattana, an independent developer focused on applied AI in financial markets. The platform grew from a personal project to monitor markets and automate trading workflows — solving the problem of having good analysis but not enough time to act on it.
Every feature in Tradewink exists because of a real frustration encountered while trading: signals with no entry plan, news alerts with no context, strategies that worked in one regime and failed in another. Tradewink is the system built to solve those problems.
The Problem We're Solving
Individual traders are at a structural disadvantage. Institutional desks have dedicated analysts monitoring dozens of data feeds, quant teams running regime-detection models, and execution infrastructure that acts in milliseconds. A solo trader has a browser tab and a Discord alert.
Tradewink closes that gap. It runs 75+ concurrent AI loops scanning earnings reports, options flow, dark pool prints, insider filings, macro signals, and momentum indicators simultaneously — 24 hours a day for crypto, full speed during market hours for equities. Every signal it surfaces comes with a full written analysis explaining the reasoning, entry zone, stop-loss, and profit target. You understand every trade before you take it.
How We Approach This
Your money never moves
Tradewink connects to your existing broker via API. We send trade orders — that's it. Your funds stay in your brokerage account under your name at all times. We have no custody of your money and no access to withdraw it.
AI validates AI
No single model makes a trade decision. Every signal goes through a multi-model validation chain: Claude Haiku extracts context, GPT-5 Mini runs quant reasoning, and GPT-5 evaluates execution risk. A reflection audit runs before any automation workflow is triggered.
Transparent, not a black box
Every signal includes the full reasoning — what triggered it, what data supports it, what invalidates the thesis, and what the expected risk/reward is. You can always see what the system is doing and why. If a trade gets rejected by risk management, you see why.
You configure the risk, we handle the rest
Before any automation runs, you define your risk parameters: max position size, daily loss limit, which instruments are in scope, and whether automation is enabled at all. The system operates within those bounds — hard stops enforced at the code level, not as suggestions.
The Technology
Tradewink is built in Python 3.12+ with an async-first architecture. Market data comes from Polygon.io (primary), with yfinance, Finnhub, FRED, and EDGAR as supplementary sources. Real-time streams include Alpaca WebSocket for live bars, Finnhub WebSocket for news, and SEC EDGAR polling for insider filings.
AI analysis routes through multiple models via OpenRouter: Claude Haiku 4.5 for context extraction, GPT-5 Mini for quantitative reasoning, and GPT-5 for execution evaluation. Market regime detection uses a Hidden Markov Model (HMM) to classify SPY into trending, choppy, and transitioning states — adjusting strategy weights and position sizing accordingly.
Broker integrations cover Alpaca, Tastytrade, Tradier, IBKR, Schwab, TradeStation, Webull, and Moomoo — all via a common broker abstraction layer. Your API keys are stored encrypted with Fernet symmetric encryption and PBKDF2 key derivation. They are never stored in plaintext and never transmitted to third parties.
Important Disclaimer
Tradewink is a technology platform, not a financial advisor or registered investment advisor. The signals, analysis, and automation features are tools to assist your own trading decisions — they are not personalized investment advice. Past signal performance does not guarantee future results. All trading involves risk, including the risk of losing more than your initial investment. You are solely responsible for your own trading decisions.
Tradewink does not hold custody of your funds, does not execute trades without your configured authorization, and is not a broker-dealer.
