This brief tutorial describes replacing the default stock-ranking model in a visual AI strategy template with gradient boosted decision tree training and prediction modules. It gives an example configuration: a regression loss, root mean squared error as the…

This article proposes comparing a model's information coefficient (IC) and mean IC across training and test samples to assess predictive stability. It defines IC as the correlation between a model score and subsequent returns, using a five-day return…

This brief explanation identifies two main reasons a quantitative factor may have low coverage: the coverage of its underlying input factors and the length of its calculation window. If an input dataset contains values for only a limited portion of the…

This Chinese-language report summarizes two overseas research papers. The first decomposes the book-to-market ratio into a market-to-intrinsic-value component and an intrinsic-value-to-book component, then examines which part relates to valuation-strategy…

The report summary describes a stock-selection factor built from a multinomial logistic model that estimates the probability of a large stock decline over the following month. It tests several decline thresholds and reports broad factor coverage, including…

This ProRealTime version 11 indicator identifies swing highs and lows using configurable counts of bars before and after each candidate point. It connects successive low fractals as support lines and successive high fractals as resistance lines, extending…

The note introduces the Accelerator Oscillator (AC) and gives its calculation from high and low prices. It first takes each bar’s midpoint, then calculates an Awesome Oscillator by subtracting a longer-period moving average from a shorter-period moving…

The research note examines two convertible bond approaches: buying bonds trading below conversion value and positioning in deeply out-of-the-money bonds. For discount arbitrage, it proposes buying the bond and shorting the underlying stock where feasible,…

This macro commentary argues that markets may shift from pricing direct conflict risk to pricing the inflation and monetary tightening that an energy supply shock could cause. It describes a possible chain from disrupted shipping through higher oil and gas…

This report overview introduces supervised neural networks, unsupervised learning, and reinforcement learning, then considers their possible roles in finance. It describes deep networks as learning nonlinear mappings through layered representations;…

This technical stock screen combines three conditions: daily price range exceeding 1% of the previous close, the session high matching the highest high of the current and prior day, and rising 5-, 10-, and 20-day moving averages. Together, these rules seek…

The note describes PATV, a stock-selection factor based on intraday trading volume. It first compares average volume over five-minute intervals with average volume over thirty-minute intervals, then ranks the resulting ratios across stocks. The factor…

This forum thread concerns a strategy that produced normal backtest behavior but no signals after submission to simulated trading. The user had removed a binding between the strategy’s start date and its live-trading parameter, then waited several days…
