Sorry, but for ZC and ZS your options are limited.
Index data, stocks, forex; no problem finding good quality data on the cheap.
Question: If you need the data for back-testing, ZC and ZS might not be the best choice. Prior to Dec 09/Jan 10, volume on both contracts were really thin. Thin volume = choppy data charts. You may have some more luck with the full-sized contracts for Corn and Soybeans.
Ok, that's great, thanks for replying. So finally, after two weeks, I can put an end to the "
look elsewhere" quest you got me started on.
And now, on with a new quest, to find out what you mean by:

I am new to these futures, but I've done some research.
I've looked it up here:
http://www.wikinvest.com/wiki/Corn_Futures
Corn futures are traded on the Chicago Board of Trade under ticker symbol C in cents per bushel. For electronic trading sessions, the symbol ZC is used.
and here:
http://www.wikinvest.com/futures/Soybean_Futures
Soybean futures are traded on the Chicago Board of Trade under ticker symbol S in cents per bushel. For electronic trading sessions, the symbol ZS is used.
So far they talk about Corn and Soybean futures and they mention the presumably standard, main and therefore what you call "full-sized" contracts and mention my symbols at the Chicago Board of Trade. So I don't see how I could be speaking about a different contract which is not the full-sized one. Please let me know if I am wrong about this.
They actually even talk about "mini-sized contracts" and have a different symbol for them here:
http://www.wikinvest.com/futures/Mini-Sized_Soybean_Futures
Mini-Soybean futures are traded on the Chicago Board of Trade under ticker symbol YK in cents per bushel. For electronic trading sessions, the symbol XK is used.
So my ZC and ZS cannot be "mini" because there are other contracts called "mini", and if they are not mini doesn't that mean they are "full-sized contracts"?
Same thing that says here:
http://www.cmegroup.com/
And, specifically here:
http://www.cmegroup.com/trading/commodities/grain-and-oilseed/corn_contract_specifications.html
and here:
http://www.cmegroup.com/trading/commodities/grain-and-oilseed/soybean_contract_specifications.html
I hope you're not referring to the difference between what they call "CME Globex (Electronic Platform)" and "Open Outcry (Trading Floor)", because in that case that's exactly the data made available by disktrading.com, but I wasn't happy with it because it only covers those few hours of "Open Outcry" (about 5 hours).
So, obviously, my question is: what "full-sized contracts for Corn and Soybeans" are you talking about if not those identified by "ZC" and "ZS"?
