I place a trade with Shorts and Longs recently on the "UK 100" Index and got stopped out at about 6p.m. Presumably there is some market in the States or somewhere where the FTSE continues to be traded after the markets have closed in the UK? I don't really like this as I don't know what's going on, and would rather trade on an index that will behave like a basket of its constituent shares, so will just be rolled over at 16:30 each day. Who offers this?
