I could not find historical data for the index or futures cfd on the links you kindly posted. Anyone has a clue on where I could find reliable historical data on index (sp500,dax30, dow jones) and commodities (crude oil, natural gas, etc.)?
I started working with the SQ Tick Downloader yesterday, actually it seems to have what I was looking for (meaning indices and commodities with a good enough historical period). Still in the learning process though. Thanks a lot. I will end up writing my review on this matter so that anyone who will have such a problem will find a benefit from this post.
Right now, if I well understood, the 90% modelling quality is enough for most of the traders and strategies and the most one can reach from 1 minute's data. And that should be enough for most of our trading systems, at least for the ones that are not scalping or anyway for those working on higher than the M1 time frame. I found it can be reached with many brokers simply using their platform data (I used Oanda and MyFxChoice for that). After that is only a matter of reliability of their data. And for that I guess one should be lucky and maybe try and compare a live test with a back test on the same period of time (even though that will not solve the problem on the reliability of the past data, it will be a good way to evaluate the recent ones ;) ).
I also found an interesting ex4 file that could be used to save our own tick data on a file (e.g. using our own trading platform on our own vps), so that we can build a proprietary historical tick data that we could use later on.
In case you are interested in it, you can find it at this url:
If you have $1000 or more in an account with Oanda, you can get the historical data for free. You just pick a time range, request the data via their site, and generally within an hour they will have a file ready for you to download.
When I create robots, I use OLSENDATA.com website. As for now I can say they are most reliable company for FX spot quotes. As You can see on my profile, robots generated on their TICK data, works flawless!
