Find high resolution market data for a single ticker? I'm doing my dissertation at the moment and for it, I need high-resolution market data. The only problem is I'm a student and haven't got much money. A lot of sites I have seen want monthly subscriptions or big upfront fees, I do not have this.

What's the cheapest way I can get 6/3 months of Tesla market data at say 1-second resolution? 

Thanks.
Many universities have access through WRDS to the NYSE Trade and Quote (TAQ) data. Despite the name, TAQ has " intraday transactions data (trades and quotes) for all securities listed on the New York Stock Exchange (NYSE) and American Stock Exchange (AMEX), as well as Nasdaq National Market System (NMS) and SmallCap issues."

Quandl has intraday data, but only at a minute level frequency. Tesla is a member of the NASDAQ 100 and so is one of the minute by minute firms available through Quandl via AlgoSeek. The pricing for an individual user for the whole year is \$800 (as of 2/2/17).
