Intraday Stock Cost Trading with Mean-Reversion and Momentum Rules

Summary

This article describes a discretionary intraday approach to trading an existing stock position in an effort to lower its effective cost. It distinguishes buying before selling in an uptrend from selling before buying in a downtrend, and frames entries around the gap between the live price, the intraday average-price line, and the session’s zero-change reference. The proposed logic is to wait through narrow ranges, trade larger deviations as potential mean-reversion opportunities, and complete the round trip near the average-price line.

The article also advises against automatically fading a sharp upward move when price continues to strengthen, treating it instead as possible momentum and holding through it. These are heuristic rules based on chart spacing, without a defined instrument universe, systematic test, transaction-cost study, or evidence supporting the claimed high win rate. The approach can misfire when prices trend rather than revert, and the document’s promotional claims about reducing costs are not substantiated by performance data.

Key ideas

• The method attempts to lower the cost basis of a stock position through intraday round trips.
• It uses price distance from the average-price line and session reference to identify possible trades.
• It recommends avoiding trades during narrow ranges where costs may outweigh small price moves.
• A persistent upward move is treated as possible momentum rather than an automatic mean-reversion signal.
• The article provides no systematic performance evidence or detailed transaction-cost analysis.
