I'm checking out kraken's new cryptowat.ch feature that seems to have much of the same features as Bitfinex - looks like a good alternative for US folks who can't get into bitfinex. - edit: they charge a monthly fee and have no where near the custom features that you cover in the 1st tutorial. But they can show RSI and ESA (without an account) and some other indicators. Haven't figured out the drawing of lines yet though.
