Function of Parabolic SAR in Forex Trading
Parabolic SAR (Stop and Reverse) aik technical indicator hai jo traders ko help karta hai trend direction ko identify karne mein aur potential reversal points ko pinpoint karne mein. Yeh indicator J. Welles Wilder ne develop kiya tha aur Forex trading mein bohot popular hai. Ab hum detail mein discuss karte hain ke Parabolic SAR kaise kaam karta hai aur isse trading mein kaise utilize kiya ja sakta hai.
Parabolic SAR Ka Function
Parabolic SAR indicator price chart ke upar ya neeche dots ki form mein plot hota hai. Jab dots price candles ke neeche hotay hain, to yeh uptrend ko indicate karta hai aur jab dots price candles ke upar hotay hain, to yeh downtrend ko show karta hai. Jab price dots ko cross karti hai, to yeh ek potential reversal point hota hai aur isse trend direction change ho sakti hai.
Indicator Ka Calculation
Parabolic SAR ki calculation complex lag sakti hai, lekin asaan hai agar aapko basic formula pata ho. Yeh indicator "acceleration factor" (AF) aur "extreme point" (EP) ko use karta hai:
- Acceleration Factor (AF): Initial value 0.02 hoti hai aur maximum 0.20 tak ja sakti hai. Yeh har bar update hoti hai jab new extreme point banta hai.
- Extreme Point (EP): Uptrend mein highest high aur downtrend mein lowest low hota hai.
Formula: SARnext=SARcurrent+AF×(EP−SARcurrent)SAR_{next} = SAR_{current} + AF \times (EP - SAR_{current})SARnext=SARcurrent+AF×(EP−SARcurre nt)
Jab SAR dots price ko cross kartay hain, to direction reverse ho jati hai aur nayi calculation shuru hoti hai.
Trading Strategies Mein Parabolic SAR Ka Istemaal
- Trend Identification: Sab se pehla step trend ko identify karna hota hai. Jab dots price ke neeche hain, to uptrend hai aur jab dots price ke upar hain, to downtrend hai. Yeh aapko trading decisions lene mein help karta hai.

Jab dots price ke neeche se upar move kartay hain, to yeh signal hota hai ke uptrend khatam ho raha hai aur aapko sell karna chahiye. Iske baraks, jab dots price ke upar se neeche move kartay hain, to yeh signal hota hai ke downtrend khatam ho raha hai aur aapko buy karna chahiye.
- Trailing Stop Loss: Parabolic SAR trailing stop loss ko set karne ke liye bhi use hota hai. Jab aap ek trend follow kar rahe hote hain, to aap SAR dots ko apne stop loss ke taur par set kar sakte hain. Yeh aapki trade ko secure karta hai aur aapko losses se bachata hai jab price reversal hoti hai.

- Lagging Nature: Jaise baaki trend-following indicators, Parabolic SAR bhi lagging nature ka hota hai aur past data pe base karta hai.
Parabolic SAR ko akela use karna bhi helpful hai, lekin doosre indicators ke sath combine karna zyada effective hota hai. For example:

Aap buy position enter karte hain aur SAR dots ko trailing stop loss ke taur par use karte hain. Jab dots price ke upar move karte hain, to aap apni position close kar dete hain aur profit book kar lete hain.
