SAREXT (Extended Stop and Reverse)

Indicator Description

SAREXT (Extended Parabolic Stop and Reverse) is an extended version of the SAR indicator, providing more flexible trend tracking and signal generation by incorporating additional parameters.

Function Information

  • Function Name: SAREXT
  • Input Parameters: High, Low
  • Parameter Settings:
    • startvalue (default: 0)
    • offsetonreverse (default: 0)
    • accelerationinitlong (default: 0.02)

  • Output: SAREXT value

Calculation Principle

SAREXT is calculated using the following formulas:

Uptrend:
SAREXT(t) = SAREXT(t-1) + acceleration * (EP - SAREXT(t-1))
Downtrend:
SAREXT(t) = SAREXT(t-1) - acceleration * (SAREXT(t-1) - EP)

Where:

  • EP (Extreme Point) is the extreme point in the trend
  • acceleration is the acceleration factor, using different initial and maximum values based on trend direction
  • The offsetonreverse parameter can be used to adjust the offset during reversals
