Hello Guys, I hope you all are doing good. Support and Resistance is the most important part of Technical Analysis. Peoples are using many different methods to drive these levels on charts. Some are using Breakout levels, Some are using trendlines and some are using averages etc. We are using put-call ratio.

If you are an options trader and following Open Interest, You can drive these levels based on Put Call Ratio(PCR) too. Today we’ll discuss this PCR.

What is Put-call Ratio or PCR?

If we divide Total Open Interest in PUT option by Total Open Interest in a Call option, The value we get is called Put Call Ration or PCR.

Let’s take an example.

Put Call Ratio

If we look at this Option chain of Nifty. Total Open interest in PUT Option is 4387350 and total Open Interest in Call option is 9885600. So Our PCR = Put Open interest / Call Open Interest, which is 4387350/9885600 = 0.44. This 0.44 is PCR for this series.


Now We know how to calculate PCR and we have individual strike Open Interest data too, so we can calculate PCR on any individual strike too. Like “what is the PCR of 11000 Strike Price?” The answer is simple PUT open interest divided by CALL open interest, Which is 11700/715425=0.01. So 0.01 is the PCR of 11000 Strike price. Same as we can calculate PCR at every individual strike price.

How can we find Support and Resistance Using this PCR”

The answer is: There are some thumb rules to track PCR. Those Rules are:

  • PCR of all strikes in the range of 0.80 to 0.50 indicates an oversold market.
  • PCR of all strike in the range 1.25 to 1.5 indicates an overbought.
  • PCR of a particular strike below .60 is strong resistance.
  • PCR of a particular strike above 1.8 indicates strong support.

Rules are very simple, You can Just write down on a paper and stick in front of your trading desk.

Now Let’s take a live example of Nifty open interest and check are these rules really working.

Put Call Ratio

This is the Options chain around 12 PM. Now look at the Open interest of 10700 and 10600. PCR at 10700 is 0.56 and PCR at 10600 is 4.55. According to thumb rules, PCR below 0.60 is strong resistance and PCR above 1.80 Strong support. Now if you look at the chart of Nifty

Nifty PCR

Nifty Trading range-bound until PCR at 10700 is below 0.60 and PCR at 10600 is at 4.55. As soon as 10700 PUT open interest start increasing and 10700 CALL open interest starts decreasing and PCR goes above 0.60, we saw a sharp move till 10720, On the other hand, PCR at 10600 still holding 4.55, That’s the reason we saw an upside movement, not a downside movement in first half today. Now let’s look at Option chain data at 1 PM.

Put Call Ratio

Now look at Open Interest at 10700, PCR almost 1 at 10700. At 1 PM look at 10600 strike price, PUT open Interest is start decreasing from 13 lakh and came till 11 lakh, which indicates that PUT writers have started square off their positions and Nifty got a sudden downfall from 10720. Now look one more time at the Option Chain after market close:

Nifty Option Chain

PCR at 10700 again below 0.60 which indicates a strong resistance zone, But at 10600 Still PCR is around 2 and that the reason Nifty took a halt around 10600 and closed at 10604.35. Now If we see PCR at 10600 is coming down from 1.80 level tomorrow than we can see some more downside levels.

Final Words:

In Stating maybe you can find it little tricky but remember one thing once you start following you don’t need to look any other indicator to find any support and resistance and you can trade along with Professionals. Remember one thing ” Practice Makes Man Perfect” So keep practice as much as you can.

  1. If the PCR value is above 1 then it indicates that there are more Puts being bought compared to Calls. This suggests that the markets have turned extremely bearish and therefore sort of oversold. ??? Vic-Vers??

  2. Dear Sachin Ji,
    Article is very informative but I have query that as it mentioned if PCR is in between 0.50 to 0.80 is Oversold Market means we can make BUY position but also same time it is mentioned that if PCR is below 0.60 it is Strong Resistance which mean there is selling pressure so SELL position we can take. In such scenario what position we need to take…..

    Also what if PCR range is in between 0.80 to 1.25 and 1.50 to 1.80

    • There are two PCRs here. One is combined PCR for all strikes and second is PCR at a particular strike.

      Thumb rules are different for both the PCRs.

  3. How come the calls and puts of any script are deciding the resistance or support of the script ? As these are not direct buy or sell orders of the script in secondary market.

    • There are certain rules to analyse open interest. If you Google it you will get so many answers. Please go through once.

  4. nice article. I have one question sir is this only helpful for nifty or i can follow in bank nifty and other actively traded stock??

  5. 1. is this method apply to particular stock?
    2. same stricke price pcr above 0.6 what cosidered? resitance or support

    • You can apply it any script. And if PCR of any particular strike is below .60, it should be considered as resistance.

  6. Sir, to follow this strategy, i will be required to be online constantly. If we can’t do it, is there any good option please?

    • Every strategy carrier a fixed limited risk. You don’t need to be online all the time. Just need to act only once we got a breakout or breakdown.
