Not exactly open source:

"Can I redistribute the market data? Unfortunately, at this time, opentick does not allow redistribution of the data due to various rules and regulations. However, when this possible, we would be happy to notify you." (from the FAQ)

but still, this is awesome... becoming a quant millionaire just got a whole lot easier ;)

I checked the site... Do they only provide an API or can we actually download the data? It looks like they charge money for NASDAQ and NYSE. It does seem like a stretch to call it open if they charge money and only provide an API.

I agree. It doesn't look like much of the data is available for free:

Historical data should be available for free. The money you pay for real-time data is the exchange fee- ie it is paid to the NASDAQ, NYSE, or whoever. The exchanges do not allow real-time data to be offered for free.

Firms that compiled the data should sell it at whatever price the market is willing to pay. Just because the value of information tends toward zero, does not mean that the price should.

I didn't know there were wannabe quants on YC. I thought they were all on nuclearphynance. ( Which you should check out if you are interested in seeing how the real quants do things. Opentick was on np about 2 years ago. )

ahh, i'm not a wannabe-quant, just a recovering former hedge fund employee.
