I do this mostly for stocks, but started doing it for bitcoin a bit ago out of fun/curiosity. I am pretty happy with how well it has turned out so far.

It takes a bit to load. It's a lot of data and I am not the best front-end dev, nor do I know someone who is. Expect to wait about a minute for it to load the actual chart.

It is the price on top, sentiment analysis on bottom. With bitcoin, a lot of times you'll see price actually lead sentiment. With stocks, as well as what appears to be with bitcoin, many of the price reductions are called in advance by sentiment, where the rises are usually lead by price...or insiders.

Nice one... I started doing something similar using twitter's real-time stream API and Python's NLTK but never had the time to finish it and fine-tune the classifier...

Awesome, you should keep going! I've only seen one other sentiment analysis of bitcoin so far, boring market!

I also use python, though I don't use NLTK. I learned python with the NLTK book though. I knew I wanted to do this with stocks, and didn't know which language to use. I eventually had a friend show me that book so python became the language.

Certainly this field will be further explored in the coming months/years. I also did it just out of curiosity. I'm not a trader, just a webdev with some python background, but I clearly see room for profit here. I mean, you just have to look to Google trends to see that 'bitcoin interest' = 'market response'.

Yeah, the idea is not new, what is most difficult is to fine-tune the Bayesian Classifier, you need to train your bots properly and separate the market sentiment. I bet with more time someone will come up with fine-tuned bots that predict the market with an astonishing accuracy, and in real-time...

Haha, yep. Some of the best indicators are the simplest. That one is good, I also measure chatter amount on Twitter and Stocktwits on bitcoin.

It doesn't seem to matter too much what the chatter is, barring very bad events like Gox. If there's a lot of discussion price is going up, at least so far. Eventually that will change once it is mainstream. For now, all press is good press, seems to be spreading curiosity for bitcoin. I know that's what brought me in.
