Top Gainers shows float and relative volume beside every move, Halted Stocks has its own scanner, and float and volume filters keep thin names out of the AI and custom scanners.

    AI Scanner

    Looks for chart patterns on the timeframes you pick (flags, double bottoms, triangles, harmonic and Elliott shapes, candlesticks) and puts a confidence percentage beside each hit. Then it narrows the list by price, change, volume, relative volume and float, and you can save your filters as presets.

    A pattern is a reading of the chart, not a prediction: you decide what to do with it.
