I'm guessing there really wouldn't be a retail fx industry if not for PDT minimums; if the SEC's intention was to prevent smaller accounts from shooting themselves in the foot trading stocks, they can now turn to forex and blow off both legs entirely. Leverage is always enemy number one when starting out.
You will be hard-pressed to find an edge; there are only a few pairs liquid enough for frequent intraday trading if that's what you're going for, and when all eyes concentrate on the same market it's much harder to squeeze out profits, vs equities where you can pick and choose your spots over hundreds of tradable entities. I would go longer term (hourly charts) in figuring out what really gets fx moving, but then you need to deal with what can happen at all hours and be comfortable with "catching up" to what the market has done while you sleep. Try if possible to trade globex futures with a multi-market platform where you can watch bonds, oil, gold, stocks etc. If you are only trading evenings/nights then you will lose out on the intermarket movement; there will be less choppiness vs day session but also less liquidity. Hope this helps some.
