The article questions the use of deep learning to forecast stock or futures returns from historical indicators. Its author says they tried both classification and regression approaches, including recurrent networks, and found the results poor. They also…

This discussion asks why a displayed time may reflect the hosting machine’s clock and how to obtain local time instead. It also distinguishes a human-readable date string from a numeric timestamp, which can be useful when a program needs to store a time…

Scalping seeks to accumulate small gains from brief price movements through frequent intraday trades. Positions may last seconds or minutes, and the approach relies on quick entries and exits, often using small time-frame charts, momentum indicators, support…

This article argues that continuing periodic fund contributions indefinitely can reduce the usefulness of later purchases for lowering average cost, while leaving a large accumulated position exposed to market declines. It uses a historical contribution…

This article presents a long-only stock strategy that buys pullbacks while short- and longer-term moving averages remain ordered upward. Its simulated rules define an uptrend as the 5-, 10-, 20-, and 60-day averages descending in value, and define a pullback…

This installment explains two parts of a spot-market strategy. Its account routine estimates total account value using available and frozen balances, marks coin holdings at the best bid, and tracks the coin share of portfolio value. If that share moves…

The article explains why backtests are approximations of live trading and compares simple bar-by-bar for-loop systems with event-driven systems that process market data, signals, orders, and fills through an event queue. For-loop backtests are easy to build…
