This document describes an alert layer for an XRSI candle and zero-line indicator. It can notify the user when the indicator crosses the zero line, when candle direction changes, when an overbought or oversold threshold is crossed, or when the indicator…
This indicator displays the colors and signal shapes produced by a separate Ichimoku candle indicator across ten configurable timeframes, ranging from hourly to monthly by default. It lets a trader compare trend conditions across several horizons on one…
This example outlines an end-to-end workflow for training and evaluating reinforcement learning agents for order execution. It covers preparing five-minute HS300 data and order files, configuring PPO and OPDS training tasks, saving checkpoints, and running a…
This short strategy description uses consecutive candlestick bars and the growth of their real bodies to generate contrarian signals. A run of N bullish bars, with each bar's body larger than the preceding one, is treated as a sell signal. Conversely, N…
This document describes a Chinese A-share stock screen that combines trading activity, a technical trigger, and a capital-flow ranking. It selects stocks with turnover between 3% and 12%, a newly formed KDJ golden cross, and positive price movement, then…
This stock-selection note proposes screening equities for an RSI below a stated threshold, seven consecutive down sessions, and turnover within a specified band. The criteria combine a momentum oscillator, a sustained decline, and a liquidity or…
This forum exchange discusses discrepancies in daily bars built from intraday data using VeighNa's PortfolioBarGenerator. A user reports that bars formed with a presumed close near the end of the session show the previous day's date and that live synthesized…
This note describes a Chinese equity screen requiring price amplitude above a threshold, a three-session limit-up sequence, and best-bid volume greater than best-ask volume. It interprets amplitude as a sign of volatility, the consecutive limit-ups as…
