Question: Can I use an ISA to invest in MT4?
The short answer to this is no you can’t.
When you trade CFDs and margin FX you are merely speculating on changes in the price of the underlying instrument and are never the owner of that instrument and that means that they can’t be housed in an ISA.
You can invest in stocks, shares and ETFs using an ISA, however, it must be a stocks and shares ISA and you should check with the ISA provider about what instruments are permitted within it, and what the charges are for dealing in them.
Saxo Capital Markets does offer a SIPP account where you can trade CFDs. However, there is a conflict as CFDs are generally for short term positions and very high risk because of the leverage, whereas SIPPs are designed as a long term investment product. that being said, if you are looking to use CFDs to short an index or specific stocks within your SIPP portfolio they can be an effective hedging tool for this.
