Ovex - okay but not good enough

Ovex offers an arbitrage service and whilst it is still beneficial and worthwhile, I would like to make a few points to note. 1. They advise they will never make a trade at below 2% profit to yourself. Dispite the premium often being fairly high at times, all of my trades have come in at below 2%, more around 1%. 2. At first it appears as if their fee is 1% of prfits - please note it is 1% of the AMOUNT YOU INVEST. So if you invest R100,000.00, they charge R1000 per trade. This is in addition to a SWIFT charge of R500 per trade. 3. There is a lack of transparency in how trades are made and no way for the investor to check that all is in order (at what premium was the specific trade made, what was the gross profit, what were the fees, etc). You have no way of telling if they are skimming profits (not saying they are, but it could easily be done with the lack of transparency).
