Indian options, read clearly

How to read this

The four signals that matter

OI

Open interest

Where the most contracts are sitting. High call OI = resistance; high put OI = support.

PCR

Put-call ratio

Total put OI ÷ total call OI. >1.1 historically bullish; <0.9 bearish. Above 1.3 or below 0.7 = stretched.

Max pain

Path of least resistance

Strike where total option-buyer losses are maximised. Markets sometimes drift toward this at expiry.

OI Δ

OI change today

New builds (positive) vs unwinds (negative). Reveals where fresh positions are being placed today.
