Bruce,
With the
MT4 that I use, I get it from Interbank FX, and I think at this time the COT indicators that they have only work with their copy. But you can download the Interbank version at their website at
www.interbankfx.com and then sign up for the
demo. Their demo provides free FX data for 30 days, and then you just make another account and can keep using it without any problems. Just make a new demo account every month.
The Shatterfield group then has the data for free up to the end of last year that can tie into MT4. You can then download the free history and try it out with the free data from the Interbank version and see how you like it. At least it's a good feel for using the COT even if you never sign up or anything. Plus they have a lot of free training and stuff on their site so you can use that as well. You may as well take advantage of them since alot of their stuff is free. If they're going to leave it open for the public, then their loss
