Ideas on where one can get viable data?

View on HN

I've heard good things about Quandl, especially if you're willing to foot the bill for some of their premium datasets.

Cheapest I can find for 20+ years us stock market data, was on eBay for $100

I would have never thought of that. Do you have any info on making a trading bot?

I am always on a look out for data... On how to build the bot, the best documentation would be your discount broker API, here is IB for example... From here the sky is the limit...

Thanks. I don't see an e-mail in your profile, but mine is in my profile. If you want to continue this conversation, hit me up.

Can you share how much computing power is needed to have a bot (or several) automating trading?

Not much to be frank, as this is not a HFT related, so basically any linux VPS will do, (I have a few around the world for redundancy)

and if it becomes an HFT situation?

for HFT, you'll need millions for infrastructure, co locating servers in the stock exchanges, etc... definitely not one man life style business...

Isn't this data the same one can get from Yahoo Finance?

Not anymore, the yahoo finance is unfortunately broken...

I have it working pulling historical data based on symbol

Sure, but there are maybe over 10000 companies including non existing ones and you need them all for your back testing to be valid...

I see your point. Scripting this and running on cron could help.

Make sure the delisted companies are included...
