Hi Xitija,I'm very glad to see another female trader on TJ.
About the question you asked-Go for BNF.Trade with just 1 lot for a month side by side with your equity trades.Once you get in-outs of BNF,you can trade with bigger lots as per your capital.Though you are doing well with equity from many years,trading stock futures sound a good idea,but,its not.In equity,you can control your share size,but in futures you have to trade in a bunch.We are helpless there.BNF is a best as compared to stock futures.
Feel Free to PM me.Bye.
