Core Usage

Trailing Stop-Loss: Used to set exit points as the trend progresses.
Trend Identification: Dots below price indicate uptrend, above indicate downtrend.
Reversal Signals: When price crosses the dots, it signals a potential trend change.

Advantages

  • Excellent for trailing stops
  • Clear entry/exit signals
  • Works well in strong trends

Limitations

  • Generates false signals in sideways markets
  • Prone to whipsaws
  • Lagging nature

Calculation Logic

SAR_{n+1} = SAR_n + α (EP - SAR_n)

Understanding the mathematical logic behind indicators helps you interpret signals more accurately and avoid misuse in unsuitable market environments.

Strategy 2

PSAR Trailing Exit

Once you are in a trade, move your stop to the PSAR dot on every bar and exit when price closes through it. Because SAR accelerates as the trend matures, the stop tightens automatically and lets winners run.

"Strongly trending markets."

Note: Technical indicators are mathematical calculations based on historical price and volume. They should be used as part of a comprehensive trading system, not as a standalone entry signal.
