I wouldn't be breaking the law, they would. And if something went wrong, I'd have zero legal recourse. GAT
Saxo allows futures trading (amongst many other assets) they are UK regulated. Their trading platform is excellent and they support automated trading via an excellent API. The downside is that they are a tad expensive and their commissions structure is not wholly transparent.
Tickmill is offering futures (CQG platforms only) now. They don't advertise an API on their site but perhaps they offer something if you contact them.
Another advantage you get with UK regulated brokers is in case a UK regulated Futures broker goes down you are covered by FCA where as US Futures brokers are not covered neither are OTC fx brokers by SIPC.. only equity brokers are .. but on other hand the broking fees in USA are very low
Nothing at all except that they do occasionally go down and I feel it's dangerous not having a backup... GAT
OK. I'm also with IB, but would like to split my account across another broker, both for financial and operational risk reduction. As I mentioned before I've been toying with Saxo Bank, but their costs are just too high. Oh well the search continues...
You can have your own account with Trading Technolgies or CQG for the API so you do not have to reprogram and use Sucden, Marex, GHF, ADM, RJ O’Brien who are all U.K. regulated futures brokers. There are probably other API’s that these brokers all support.
