One step at a time there newbie.
Pick a market - Indexes or Forex - and then roll w/ it. The grass may look greener on the other side initially, but this business is hard enough as it is w/o trying to be a market master in multiple, different markets.
I personally would suggest the regulated world of the US futures contracts.
INDEXES: ES, YM, NQ
BONDS: ZB, ZN, ZF
You can't go wrong IMO with any of those. I would pick one subgroup (indexes or bonds) and then focus on that subgroup - meaning, watch the ES and NQ while trading the YM. You don't have to trade the ES or NQ, but just see how the react in comparison to the YM. The moves should be similar, but also a little different.
This thread is a good little thread about bonds. I'm having a field day in bonds lately and barely even look at the ES anymore. Of course this depends on your trading style, but I think too many overlook bonds in their search.
If you need some software, I would demo
Open ECry's. It's free to customers and you can get a free trial as well. I believe the trial is 2 weeks, but if you ask nicely, you should be able to get an extension on that if needed. Data IS INCLUDED in their package. Hard to beat.
