KDJ J-Line Crossovers for Momentum Entries and Exits

Summary

This document describes a long-only strategy built around the KDJ oscillator, calculated from the position of the close within a recent high-low range and smoothed into K, D, and J lines. Its entry rule buys when J crosses above a configurable lower threshold. It exits when J crosses below an upper threshold or crosses below K while above the midpoint, treating that latter event as possible momentum exhaustion.

The source code specifies example trading assumptions, including percent-of-equity sizing, commission, slippage, and order processing at bar close, but the document supplies no backtest results or comparative evidence for the claimed edge. Thresholds and oscillator lengths are configurable, so behavior depends on parameter choices and market data. The description presents the J line as a sensitive signal for reversals and continuation, but offers no filters, short trades, protective stop, or validation across assets and timeframes. Transaction costs and false crossovers may affect outcomes.

Key ideas

• The oscillator derives KDJ values from the close's position in a recent price range.
• A long entry occurs when the J line crosses above a configurable lower threshold.
• The strategy exits on an upper-threshold crossunder or a J-line cross below K above the midpoint.
• The document provides implementation assumptions but no empirical performance results.
• Parameter settings and market conditions may change signal behavior.
