Why Thastock exists.

Most retail traders use a broker's built-in watchlist (laggy, no alerts), a screener website (paywalled, no portfolio sync), and some ad-supported chart tool. There is no single place that combines real-time alerts, technical screening, insider flow, AI research, and a morning brief — at a price that makes sense for individual traders.

Thastock is a market intelligence platform for active traders. It runs alerts on RSI, price, volume, and MA crossovers. It pulls insider flow from SEC filings. It runs AI against your tickers each morning. It scores your portfolio's risk in real time. The goal is one dashboard that replaces four different browser tabs.

We do not give investment advice. We do not recommend what to buy or sell. We show signals and data — you make decisions. The disclaimer on every page is not boilerplate; it is accurate. Thastock is an information tool, not a trading advisor.

RSI is calculated using Wilder's smoothed method, 14-period by default. Volume spikes compare last session vs trailing 20-day average. AI summaries are generated at query time, not cached — you get a fresh read each time. Signal logic is open and inspectable — no black boxes.
