This analysis compares limit-up activity in Chinese equities around the implementation and anticipation of registration-based reforms. It reports that daily limit-up counts fell in the later part of the observed half-year, with lower five-day averages and no…

This implementation explains how a bivariate Gaussian copula represents dependence between two variables after their observations have been converted to uniform pseudo-observations. It estimates the dependence parameter by mapping those observations through…

This document describes a short-term stock selection screen focused on China’s metaverse industry. It looks for simultaneous bullish crossovers in MACD, KDJ, and DMI, with MACD above its zero line. The expanded rules also require the MACD fast average to be…

The post describes a China-focused stock screen combining three conditions: RSI below 65, membership in the beverage and alcohol import-export industry, and a short moving average above a longer one. Its example specifies a 14-period RSI and compares…

This Chinese stock-selection example combines four conditions: price amplitude above 1, exclusion of ST-designated stocks, a five-session upward condition, and a buying-control measure above 21. The accompanying Python illustration estimates amplitude from…

This forum question concerns modifying a portfolio sell routine so that, when the stock allocation exceeds 60% of total portfolio value, the excess exposure is reduced by selling holdings from the bottom of a ranking. The supplied code builds a set of…

This stock-selection example screens Chinese A-share stocks in the metaverse category, requiring prior-day turnover above 8% and a three-part price condition labeled as the start of a main advance. The accompanying formula expresses the price checks as the…

This note describes a trailing stop indicator that sets long and short thresholds as a percentage of each bar’s high and low. While a position direction continues, its stop is updated to move with price; a crossing of the active stop switches the direction.…

This Chinese equity screening proposal combines turnover between 3% and 12%, a positive but limited ten-day gain, and an upward-diverging moving-average pattern. Its accompanying example adds exclusions for certain exchange segments, special-treatment…

The article explains robust portfolio optimization as a way to reduce the effect of errors in expected-return forecasts. Rather than optimize only for a single set of estimates, the methods consider adverse plausible cases and seek a portfolio that performs…

The document proposes a Chinese equity screen combining three filters: metaverse-related stocks, positive institutional flow, and tickers beginning with the Shanghai “60” prefix. It also presents a Python example that layers in additional selection steps,…

This study examines whether investors chasing Morningstar mutual fund ratings can move stock prices through fund flows. Before Morningstar’s June 2002 methodology change, ratings were closely tied to broad fund performance and therefore favored some…

The document is a user’s request for help translating indicator values and candle direction into strategy conditions. The proposed rules are to open a long when a bullish candle aligns with a red volume bar, and to open a short when a bearish candle aligns…

This comparison explains differences between TqSdk and vn.py that matter when adapting existing trading strategies. vn.py is presented as an integrated package with market data, trading connections, storage, and interface components. TqSdk instead uses…

This article outlines a two-part FMZ design for forwarding futures position changes from a reference account to one or more synchronizing accounts. A template library runs inside the reference strategy, records initial long and short position amounts, checks…

The document explains how Hyperliquid handles leveraged positions when account equity falls below maintenance margin. It first attempts to close positions with market orders on the book, allowing full or partial fills; any remaining collateral stays with the…

This stock-selection rule screens for securities with a 14-period RSI below 65, greater volume at the best bid than at the best ask, and a positive daily price change. The document interprets the RSI condition as a way to identify relatively weak or…

The article discusses data integration challenges when developing strategies across US equities and forex. It highlights differences in update speed, price conventions, and data formats, arguing that timestamp misalignment and latency can create gaps between…

This document outlines operational rules for an automated strategy associated with Bollinger Bands, although it does not specify the precise band conditions that trigger a buy or sell. The system evaluates signals on a new bar and allows the number of open…

This indicator combines a Stochastic Oscillator with Bollinger Band width to flag flat market conditions. It treats a narrowing Bollinger range as evidence of a flat state, with the band’s half-width compared against a configurable threshold. During the…

The article proposes reducing noise in stock prices with wavelet decomposition, fitting ARMA models to the resulting coefficient series, forecasting those coefficients, and reconstructing a one-step-ahead price estimate. Its denoising explanation relies on…

This indicator combines a volatility squeeze measure with a separate reading of trend direction and strength. A squeeze is identified when the Bollinger Bands sit inside the Keltner Channel, which the description treats as a sideways phase. The histogram…

The document describes a basic signal based on a closing price moving beyond the upper or lower Bollinger Band. Such a breach can be interpreted in two different ways: as evidence of a reversal or as the start of a trend. The proposed use is to display…

This indicator calculates conventional pivot levels from the prior period’s high, low, and close, with selectable daily, weekly, monthly, or four-hour periods. It uses the resulting range to plot a central pivot, three resistance levels, three support…
