A very long streak indeed, it certainly has a nice smooth equity curve, but I am not sure it makes great profits. Very often these things are mutually exclusive.
The oher good thing about these 2 is the almost unlimited liquidity. It doesn't do you any good to master trading in something that is too illiquid to make huge trades in if you get really good at it. Maybe you can make a profit almost every time trading tiny amounts, but that's useless if you can't plow all those profits back into trading larger and larger amounts of the same instrument.
There's lots of stuff to trade, that's for sure, but liquidity is crucial if you ever have plans of trading huge amounts of $$ in whatever you are trading.
