Charles Schwab and Tradewink: AI Research and Paper Tracking

Charles Schwab brings institutional-grade infrastructure to automated trading. As the largest brokerage in the United States following its acquisition of TD Ameritrade, Schwab offers stability, regulatory compliance, and execution quality at scale. For traders who need a broker they can trust with larger portfolios, Schwab provides the reliability that smaller fintech brokers cannot match.

Tradewink can't connect a Schwab account for trading — not through direct Schwab OAuth and not through SnapTrade. Public subscriptions are paper-only; separately approved private beta accounts may submit live broker orders. Tradewink doesn't connect to thinkorswim paperMoney either.

For automated stock trading, Schwab's API supports all standard order types: market, limit, stop, stop-limit, and trailing stop. It provides real-time account data including positions, balances, order status, and transaction history. Schwab's execution quality is consistently rated among the best in the industry, with meaningful price improvement on limit orders — a tangible advantage for anyone placing hundreds of trades per month.

The thinkorswim platform, now fully integrated into Schwab, offers research tools, charting, and a paperMoney simulator. It pairs naturally with Tradewink: use Tradewink's AI research and signals to find ideas and paper-track them in Tradewink's simulator, then use thinkorswim for your own analysis and for any real orders you choose to place.

Schwab's fractional share support (Schwab Stock Slices) enables precise dollar-based position sizing for portfolio management. You can allocate exact dollar amounts to each position rather than rounding to whole shares, which improves portfolio balance and risk distribution. Combined with commission-free stock and ETF trading, Schwab removes two of the biggest cost barriers to frequent trading.

What Tradewink does for Schwab traders: AI research and signals on the stocks, ETFs, and options you can trade at Schwab, Paper Autopilot paper tracking in Tradewink's simulator, and a journal of those paper trades. For public-plan users, any real trade is your own decision, placed by you at Schwab, outside Tradewink.

Tradewink's Model Context Protocol (MCP) server works without a broker connection. With Claude Desktop, Cursor, VS Code, or any MCP-compatible client you can run multi-agent research on a ticker you trade at Schwab and check your Tradewink paper positions — all secured by OAuth 2.1 with no API key pasted into the client.
