Use IG and City Index- both very good platforms. I swing trade for months and use them for leverage as I only trade shares tax free (IS/PEP/SIPP).
I find both very good: will be v helpful when closing large positions at tops and you can beat IG's bias (worse than City imo) by buying/selling on down/up days near start/end of trends.
money mangement and TA are key imo to making money.... nothing to do with sbs .. And yes I have 5 figure profits and accounts still open:-)
EDIT: and I operate well within my limits.. A margin call means you sell or buy when you least want to....
