You did ask for opinions. Here are mine: a 14%/year ROI is pretty good unless you are working yourself into a frazzle to achieve that. There are big-time fund managers who consider 10% a good return.
Obviously
some brokers do stop-hunt just as some brokers guarantee stops - until they decide not to honour their "guarantee". But ALL brokers don't do those things. ( no I'm not a broker or industry professional.)
Trading is no easier in a regulated market. If you try ES I think you may find it just as exasperating as forex if not more so. Since the stock market ( by extension the stock indices) operate on the "greater fool" principle price action there is even less rational than in the spot currencies. (This is very much the voice of experience speaking to you now.)
But it's your time your money. Whatever direction you decide to take I wish you well.
Cheers!
