A lot harder if you don't trade via an ISK which I don't. Declaring taxes is a pain in the ass trading different instruments via CFDs.
Sure outside ISK is a pain in ass to list everytrade. Within ISK you can do options and mini futures which is pretty much all I need and beneficial with the tax rate so low at the moment. Who do you use in Sweden for CFD? Mostly I use Avanza with smaller amount at Nordnet.
I use an Australian broker, mostly because they have low spreads and provide mt4 for free. Having to pay extra for shitty charting software is why I don’t use avanza and nordnet. Last time I traded mini futures you couldn’t set a stop loss and that’s just a big no no. I tried working around it by creating an alert in the underlying asset at a certain price which would then trigger a market sell order in the mini future. But it didn’t work most of the time and was sketchy to say the least.
