DD Trader, for me it’s a question of preference and where you are in your day trading journey.
I found spread accounts a good starting point – there’s no commission to factor in, which can make calculating costs more convoluted. There’s so much to learn and do at the beginning as it is.
Nowadays I mainly opt for commission pricing for some of the reasons outlined by Seb. Ultimately I’ve found commission accounts cheaper overall, so they make sense when you’re ready.
