I have found Tone Vays and his website quite helpful, as well as Bitraged. They have both been fairly accurate in their calls, they are both very conservative and "safe" in their calls though.
But remember just "knowing TA" doesn't mean you will trade positively. I myself have rather been trading off news and launch dates to increase my BTC. This has been much more profitable to me, knowing when a chart is turning bearish is useful though.
P.S. Don't watch Tone's channel if you can't handle him calling each and every altcoin **** that is going to zero.
