Tax treatment of capital gains received from USA-based LLC

Hi, I am a UK citizen. I am shortly joining a USA-based LLC (Limited Liability Company), which will be trading derivatives (options & futures) and stocks in USA stockmarkets. There is no other business being carried out by this LLC. The intention is to distribute the capital gains (if any), after payment of appropriate USA tax at source which arise for the LLC. I just wanted to confirm that I will be eligible for claiming back any further tax which might be applied by HMRC, in accordance to the Double Taxation Convention (signed on 24th July 2001). Thank you in advance. Sarvan
