I want to separate my stocks out a bit between growth/dividends and swing trading. Is it worth putting one type in Invest and other in ISA? Many stocks will be kept long term and at the same time the same stock will come and go over weeks and having them both in one location could be confusing.
For tax purposes put as much into the ISA as you can. The accounts have the same functionality. The only difference is the tax exemptions in the ISA
