ETX Capital. http://www.financial-spread-betting.com/etx/ETXcapital-review.html Which spread betting markets are most popular with clients? Manoj Ladwa, Senior Trader and Market Commentator at ETXCapital comments. I think it changes according to what markets are faring. Commodities are all the rage at the moment with gold's strong performance. Currencies have slowly declined but are coming back as the USD creeps up.
