Trading foreign exchange is exciting and potentially very profitable, but there are also significant risk factors. It is crucially important that you fully understand the implications of margin trading and the particular pitfalls and opportunities that foreign exchange trading offers. On these pages, we offer you a brief introduction to the Forex markets as well as their participants and some strategies that you can apply. However, if you are ever in doubt about any aspect of a trade, you can always discuss the matter in-depth with one of our dealers. They are available 24 hours a day on the Saxo Bank online trading system, SaxoTrader.
Terms of trading are agreed individually depending on the volume of your transactions, but are generally much lower in cost when compared to banks and brokers. Your margin deposit can be cash or government securities, bank guarantees etc. Large corporate or institutional clients may be offered trading facilities on the strength of their balance sheet. The minimum deposit accepted for an individual trading account depends on the account type. Trade confirmations and real-time account overview are built into SaxoTrader, while further account information can be produced in accordance with your specific requirements.
