Practical Example of Option Chain Analysis
Suppose the market data is:

|---|---|---|
| 22,400 | 120,000 | 80,000 |
| 22,500 | 150,000 | 110,000 |
| 22,600 | 170,000 | 200,000 |
Total Call OI = 440,000
Total Put OI = 390,000
PCR calculation:
PCR=440000390000โ=0.886
Result
A PCR below 1 indicates slightly bullish market sentiment.
Highest Put OI is at 22,600, which may act as support.
Highest Call OI is also strong near 22,600, suggesting resistance pressure.
