# Data request: Option prices for a liquid index/stock

Currently doing a course project on option pricing as a part of my undergraduate studies. However I cannot find a free dataset $$D=[d_1,d_2,...,d_N]$$, which would represent a time-serie of daily option prices across all strikes and maturities. (Let $$d_1$$ denote the $$k$$ $$\small{\text{x}}$$ $$m$$ matrix of daily option prices. $$k$$ is the number of strikes and $$m$$ is the number of maturities).

I would be pleased if someone could provide me a sample (Do not need larger than 20-30 matrices, so 1 month of daily prices is perfect). Preference about certain dates, stock or index is irrelevant.

I just need a good training set.
