This depends on what you are trading, as fees can vary quite widely at the broker. For example, all CFD and spread betting trades are executed on a commission-free basis - apart from stocks and shares. Spreads are as low as 0.3 pips on gold and 0.7 pips on major forex pairs, which is very good. But, the spreads on US treasury bonds are as high as 3 pips. All in all, CMC Markets is relatively competitive, but not across all of its asset classes.
