Thanks. I will look into it. What I have done was recreate a 'fake' data feed that feeds data to my program. I take historical data and pass it to the program which then recreates tick by tick market conditions. I won't go too far into it :P

If you're stuck learning python, I would recommend www.codecademy.com . Their python course is great and the functionality of the website makes learning the language a fast and above all enjoyable process.

It is alright for historical data but most of the sites on the webpage don't allow you to go back that far. I won't be dropping my subscription anytime soon.
By now, I seriously can't tell if you are one well programmed troll bot or some stupid kid.

Apparently ****posting is.

It takes two! You receive an e-mail whenever someone quotes you. That's not rocket science. I doesn't take long to post a reply from my phone.

I'm not sure if Quantopian offers Forex data? I though they only focused on stocks, ETFs, and indices?

If you are serious about trading and need a real-time data feed plus historical data - I would open an account with Interactive Brokers. As long as you meet their minimum account size requirement (which I think is $10k in US, should be similar in the UK - you will get access to whatever data you need, and Forex data is free from them.. incl. intra-day.

Also, if you are interested in Forex specifically - get a demo account from any broker that offers MetaTrade platform - they will offer historical forex data free of charge, you can download and store in text files on your computer. Just beware if you decide to trade through them, a lot of MetaTrader brokers are bucket shops... (not all though).

You could begin testing with Yahoo Finance API.
I had recently uploaded a python program on github which is pretty simple to understand and may assist you in implementing your knowledge of computational finance over the variables provided by yahoo finance in .CSV format.
Have a look at https://github.com/techite/Financial...tockDisplay.py

They have plans for that. There is another one, quantiacs that focuses exclusively on futures. Quantopian appears more popular. I am working on first algo since Price Action Lab recently added a feature for generating code for it.

Quantopian uses an algo to estimate impact of commission and partial fills. This is very good. I have tested some systems and I found a small effect in performance due to Quantopian estimated slippage but not very high.

There are some other services I have not tried like QuantConnect. I will be looking at quantiacs soon.
