This brief indicator note introduces Island Reversal, abbreviated IR, and lists its inputs as close, high, low, a lookback length, and a percentage parameter. Its pseudocode calculates prior-period high and low boundaries, then derives two price levels…
This post outlines a stock screen that combines a daily price-range threshold with a rising DEA signal, while applying geographic exclusions. It then suggests expanding the screen with valuation measures such as price-to-earnings and price-to-book ratios,…

The report describes stock-return prediction with machine-learning models built for short, medium, and long forecast horizons. It groups selection factors according to their information coefficients at different horizons, reflecting the idea that factor…
The post asks whether a feature expression can take the maximum of four moving averages and whether a similar expression can calculate their standard deviation for one day. The example uses 5-, 10-, 30-, and 60-day averages as four contemporaneous values,…
This stock screen combines three conditions: membership in the metaverse industry, a 2021 listing year, and an opening price near the ten-day moving average of closing prices. The accompanying example describes both a crossover-style technical condition and…
This implementation describes a threshold-based rule for a cointegrated pair. It opens a long-spread trade when the spread falls to or below a lower entry level, or a short-spread trade when it rises to or above an upper entry level. A trade closes when the…
This report outlines a first step in building a multifactor model: choosing which factors to combine. It proposes screening combinations using three criteria: how strongly a factor differs from benchmark exposure, how correlated the factors are with each…
This Expert Advisor uses the Money Flow Index (MFI) as a threshold-crossing signal. It sells when the oscillator crosses downward through an overbought level and buys when it crosses upward through an oversold level. Signals are evaluated at bar close, so…
