Parabolic SAR Direction Changes as Buy and Sell Signals

Summary

This document describes a Parabolic SAR signal indicator that classifies direction by whether the SAR value is below or above the closing price. A change from below to above the price produces a sell signal, while a change from above to below produces a buy signal. The script plots the SAR direction, colors bars, and can submit long or short entries when the direction flips. Start, increment, and maximum parameters control the SAR calculation.

The material provides indicator logic and a published Bitcoin futures chart configuration using 15-minute bars with five-minute base data over about a month. It gives no reported returns, trade statistics, or evaluation of signal quality. SAR flips can lag price changes and may produce repeated reversals in ranging markets; the document offers no additional trend filter or explicit risk controls. The example therefore explains how to generate directional signals, but does not establish that they form a profitable trading system.

Key ideas

• Parabolic SAR position relative to the close defines the current bullish or bearish direction.
• A direction flip generates the corresponding buy or sell signal and can trigger an entry.
• The SAR start, increment, and maximum settings shape the indicator's behavior.
• The published chart configuration supplies no performance evidence or risk management rules.
• Directional flips may be delayed and can whipsaw in sideways markets.
