NSE options chain: OI buildup, PCR, max pain, IV (Nifty/BankNifty).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NSE Options
Analyze NSE options chain for Nifty and BankNifty — open interest buildup, put-call ratio, max pain level, and implied volatility — using NSE's public JSON API.
## When to Use
- User asks for Nifty or BankNifty options chain
- User wants to know the PCR (put-call ratio) for an index
- User asks for max pain or peak OI strikes
- User wants to see OI change at specific strike prices
- User asks about ITM/OTM options or IV skew
## How to Use
### Fetch options chain for Nifty
```powershell
$headers = @{ "User-Agent" = "Mozilla/5.0"; "Referer" = "https://www.nseindia.com" }
Invoke-WebRequest -Uri "https://www.nseindia.com" -SessionVariable nse -Headers $headers | Out-Null
$chain = Invoke-RestMethod -Uri "https://www.nseindia.com/api/option-chain-indices?symbol=NIFTY" `
-Headers $headers -WebSession $nse
$chain.records.data | Select-Object strikePrice,
@{N='CE_OI';E={$_.CE.openInterest}}, @{N='CE_IV';E={$_.CE.impliedVolatility}},
@{N='PE_OI';E={$_.PE.openInterest}}, @{N='PE_IV';E={$_.PE.impliedVolatility}} |
Where-Object { $_.CE_OI -or $_.PE_OI } |
Sort-Object strikePrice
```
### Calculate PCR (Put-Call Ratio)

How to install
mdr add taracodlabs/aiden/nse-options@sha256:c479a98b1a2c7e92The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
