Donāt worry have a fish around on this forum with the search bar there is tonnes of information. This is an article from one of the freetrade team @Freetrade_Team that should answer some of your questions (and may lead to more, in which case ask!)
Itās weird that I mentioned here that it was 6 months ago that I joined the forum as I have literally just gotten my 1 year badge! Clearly I have been on here longer than I thought!
