This Chinese-language article describes an equity screen based on price amplitude, prior-day trading activity, and opening-auction turnover. The stated final rule selects stocks whose amplitude exceeds one, whose prior-day turnover exceeds 60 million, and…
This intraday strategy for the DAX uses three consecutive candles of the same color as its directional condition. On the one-hour chart, it allows a long entry at noon when the current and prior two candles have all closed above their opens. It allows a…
This Chinese-language description outlines an equity screening rule that combines a daily amplitude threshold, a high equal to the highest high across two days, and positive afternoon large-order net inflow. Its rationale is to pair price movement and a…
The U Trend Sensor is an oscillator built from two triangular moving averages with different lookback periods. Each average is updated only when it moves beyond a percentage threshold relative to its current level, creating step-like series. The indicator…
The Trend Levels indicator uses the highest high and lowest low over a configurable lookback period to identify potential changes in direction. A new period high sets an uptrend state, while a new period low sets a downtrend state; arrows mark those…
This commentary reviews the Chinese quantitative-investing environment in 2022 and presents a private manager’s expectations for 2023. It attributes a difficult path to excess returns to weak trading activity and rapid shifts in market style, alongside a…
This stock-selection screen combines three conditions: daily high-to-low range above 1% of the opening price, prior-day trading activity above the stated threshold, and a positive weekly MACD condition. The document presents the rules as a way to focus on…
This weekly report compares artificial intelligence stock-selection portfolios across broad A-share universes, industry-neutral portfolios, and portfolios restricted to the CSI 300 or CSI 500. It names XGBoost, support vector machines, random forests,…
The document outlines a daily, after-close stock-selection screen that requires the MACD line to be above zero, limits the universe to companies with floating market capitalization above 10 billion yuan, and ranks candidates by a measure of individual-stock…
The document describes an A-share stock screen intended to find possible short-term rebounds. It combines a 14-period RSI below 65, first-level bid volume greater than ask volume, and a stated daily maximum decline between 4% and 5%. The accompanying…
The document presents a Chinese A-share backtest question: after selling a holding at the open, a daily-frequency strategy places a purchase near the close but buys only a small amount. The author wonders whether the simulator updates available cash only on…
This document presents a Chinese stock screening rule combining daily amplitude above 1, a newly formed KDJ crossover, and circulating market capitalization of at least 200 million. It describes the crossover as a possible sign of improving sentiment and…
The Percentage Volume Oscillator (PVO) compares a fast and a slow moving average of tick volume to describe changes in volume momentum. The indicator can display its main line, a signal line, and a histogram, with configurable periods and moving-average…
This document describes a short-term Chinese stock screen that looks for shares with an amplitude above 1, evidence of main-force control on the prior day, and a current-day low between 4% and 5% below the previous close. The stated rationale is to focus on…
The document introduces Markov chain Monte Carlo as a numerical approach for approximating Bayesian posterior distributions when analytical integration is impractical, especially in models with many parameters. It explains the Metropolis algorithm as a basic…
The document describes a short-term Chinese equity screen combining turnover, recent price performance, and limit-up frequency. It selects stocks with turnover between 3% and 12%, a positive 10-day gain below 35%, and more than two limit-up sessions during…
