पैराबोलिक SAR संकेतक
परवलय एसएआर संकेतक क्या है?
प्रवेश बिंदुओं की पहचान करने के लिए, सूचक “एसएआर” नामक अनुगामी स्टॉप और रिवर्स विधि का उपयोग करता है । व्यापारी संकेतक को पैराबोलिक स्टॉप और रिवर्स, परवलयिक एसएआर या पीएसएआर के रूप में भी संदर्भित करते हैं।
पैराबोलिक एसएआर संकेतक एक चार्ट पर डॉट्स की एक श्रृंखला के रूप में प्रकट होता है, या तो किसी परिसंपत्ति की कीमत से ऊपर या नीचे, उस दिशा के आधार पर जो कीमत बढ़ रही है। एक बिंदी को उस कीमत से नीचे रखा जाता है जब वह ऊपर की ओर चल रही होती है, और कीमत से ऊपर जब वह नीचे की ओर होती है।
चाबी छीन लेना
- पैराबोलिक एसएआर (स्टॉप एंड रिवर्स) इंडिकेटर का उपयोग तकनीकी व्यापारियों द्वारा ट्रेंड और रिवर्सल को स्पॉट करने के लिए किया जाता है।
- संकेतक एक मूल्य चार्ट पर सुपरइम्पोज़ किए गए डॉट्स की एक प्रणाली का उपयोग करता है।
- एक उलट तब होता है जब ये डॉट्स फ्लिप करते हैं, लेकिन एसएआर में एक उलट संकेत जरूरी नहीं है कि कीमत में उलट हो। एक PSAR उत्क्रमण का अर्थ केवल यह है कि मूल्य और संकेतक पार हो गए हैं।

How to Calculate the Parabolic SAR Indicator
There are lots of things to track when using the parabolic stop and reverse indicator. One thing to constantly keep in mind is that if the SAR is initially rising, and the price has a close below the rising SAR value, then the trend is now down and the falling SAR formula will be used. If the price rises above the falling SAR value, then switch to the rising formula.
- Monitor price for at least five periods or more, recording the high and low (EPs).
- If the price is rising, use the lowest low of those five periods as the prior PSAR value in the formula. If the price is falling, use the highest high of those periods as the initial prior PSAR value.
- Use an AF of 0.02 initially, and increase by 0.02 for each new extreme high (rising) or low (falling). The maximum AF value is 0.2.
- Ideally, utilize a spreadsheet where the high and low price, SAR, EP, and AF can be tracked on a period-by-period basis.
traders only need to know how to interpret the indicator’s signals.
What Does the Parabolic SAR Indicator Tell You?
The parabolic indicator generates buy or sell signals when the position of the dots moves from one side of the asset’s price to the other. For example, a buy signal occurs when the dots move from above the price to below the price, while a sell signal occurs when the dots move from below the price to above the price.
Traders also use the PSAR dots to set long. If the price drops below the PSAR, exit the long trade.
The PSAR moves regardless of whether price moves. This means that if the price is rising initially, but then moves sideways, the PSAR will keep rising despite the sideways movement in price. A reversal signal will be generated at some point, even if the price hasn’t dropped. The PSAR only needs to catch up to price to generate a reversal signal. For this reason, a reversal signal on the indicator doesn’t necessarily mean the price is reversing.
The parabolic indicator generates a new signal each time it moves to the opposite side of an asset’s price. This ensures a position in the market always, which makes the indicator appealing to active traders. The indicator works most effectively in trending markets where large price moves allow traders to capture significant gains. When a security’s price is range-bound, the indicator will constantly be reversing, resulting in multiple low-profit or losing trades.
For best results, traders should use the parabolic indicator with other technical indicators that indicate whether a market is trending or not, such as the average directional index (ADX), a moving average (MA), or trendline. For example, traders might confirm a PSAR buy signal with an ADX reading above 30 and a bounce for a long-term rising trendline.
The Parabolic SAR vs. a Moving Average (MA)
The PSAR and MAs both track price and help show the trend, but they do it using different formulas.
An MA takes the average price over a selected number of periods and then plots it on the chart. The PSAR looks at extreme highs and lows and then applies an acceleration factor. These varying formulas look very different on the chart and will provide different analytical insight and trade signals.
Limitations of Using the Parabolic SAR Indicator
The parabolic SAR is always on, and constantly generating signals, whether there is a quality trend or not. Therefore, many signals may be of poor quality because no significant trend is present or develops following a signal.
Reversal signals are also generated, eventually, regardless of whether the price actually reverses. This is because a reversal is generated when the SAR catches up to the price due to the acceleration factor in the formula. Therefore, a reversal signal may get a trader out of a trade even though the price hasn’t technically reversed.
