# Option Chains

`GET` `https://api.unusualwhales.com/api/stock/{ticker}/option-chains`

Returns all option symbols for the given ticker that were present at the given day.

If no date is given, returns data for the current/last market day.

You can use the following regex to extract underlying ticker, option type, expiry & strike:
`^(?<symbol>[\w]*)(?<expiry>(\d{2})(\d{2})(\d{2}))(?<type>[PC])(?<strike>\d{8})$`

Keep in mind that the strike needs to be divided by 1,000.
