candles, Fibbonachi, levels of support and resistance an so on...
I know that this market is more volatile.... So will these instruments be useful here?
There are indeed a lot of similarities between the two. I use indicators in Bitcoin's charts, such as RSI or RSI Stoch. I also use tools such as Bollinger bands and SMA. And I find them to be accurate enough to give me a good indication of the trend.
There is, however, very often less data to run your analysis on. Apart from BTC, Litecoin and a few others there are not many coins that have enough volume history to base a good and reliable technical analysis on.
This can be your main problem, especially with new coins. The shorter their history, the less accurate your analysis will be due to a lack of enough data to create a pattern that can be studied.
