NineThirty serves as an AI-driven stock screener and backtesting tool designed for US equities and ETFs. It allows users to describe a setup in simple terms, automatically generating the filtering logic that incorporates over 40 technical indicators with adjustable parameters. Additionally, it integrates more than 20 fundamental metrics derived from the income statement, cash flow, and balance sheet, as well as news that is filtered based on sentiment and impact. It also accounts for corporate actions like insider trading, allowing for conditions to be combined using AND and OR logic, so that the entire setup can be represented in a single expression for a specific time bar. Users have the flexibility to define custom candle sizes ranging from minutes and beyond, rather than being restricted to set timeframes. After creating the screen, you can backtest it to evaluate its performance, including how frequently it triggered for each stock, the historical win rate, average returns, optimal holding periods, and a trade log detailing maximum favorable and adverse excursions for every instance. This method provides historical insights with the typical limitations of hindsight, rather than serving as a direct trading signal. Furthermore, DrMarket, an AI analyst with multiple agents, is available to respond to inquiries regarding live setups based on first-party computed data, and it meticulously links each statistic back to its original source for transparency. This comprehensive approach ensures that investors have access to thorough and reliable information when making decisions.
