What’s the best technical indicatorfor an altcoin?
Who knows.
You should be asking if technical analysis will apply for your altcoin at all.
In any case, markets are small and available leverage easy to get. In some cases, like with LTC or ETH, the leverage available is 20x or more. LTC is traded on Okcoin, ETH has futures on BitMEX. It’s easy to be a whale and manipulate the markets.
Usually, if a trend is good, some changes in volume should occure before a spike or chop. But volume indicators should only be applied above certain daily volume. Otherwise the market is too susceptible to manipulation.
Daily volume
You can see volume for last 24 hours on coinmarketcap.com. You should be looking at 100k USD and up if you want to use TA meaningfully.
That’s not to say you shouldn’t trade anything else. It’s just that your everyday usual normal technical analysis won’t work there.
Take for instance Lisk and The DAO. Both these things were launching on Poloniex (and elsewhere) at close dates. In both cases there was ICO (initial coin offering) where people could buy the token with a discount.
Very similar situation but different sentiment. There was a lot of talking about DAOs in general (that they are pretty much nonsense). There was no such talk about LISK.
Even though the long term value is questionable in both cases, people launched the trading with the sentiment “new playground for traders, upupupupup free money” in the case of Lisk and with the sentiment “where can I short it?” in the case of The DAO tokens.
What to look for?
1/ News
Read forums, slack chats, gitter chats, idiotic click baits in well-respected printed media etc. Forget about truth or justice. Buy the rumor, sell the news.
2/ Price
Set up price alarm. For altcoins it’s easy to do on mobile with app called TabTrader. It’s free. On desktop you can try cryptowat.ch and bitcoinwisdom.com. During rally though cryptowat.ch tends to lag.
Once there is a spike or chop in price, it’s generally good idea to trade it as it usually doesn’t end after the first leg. Unless it is a head fake, a fake movement that will turn into big trend in the other direction. Look for price patterns, more on that in the resources section further down.
Indicators that will tell you if the altcoin has enough juice to carry on the movement it started are momentum indicators. They are all lagging though - based on past price only. Look for patterns and use indicators only for confirmations.
3/ Volume
Sometimes, when the volume of the altcoin is good enough, you will see increase in buying volume before the price moves up or increased selling volume before the price drops. There are volume based indicators that follow just that.
Bitcoinwisdom has CMF - Chaikin money flow which is probably your best option.

Cryptowatch has OBV - on balance volume. To spot emerging trend on Cryptowatch you can also use Aroon even though it’s a momentum indicator.

Resources to learn technical analysis
You won’t find here any resources that give explicit trading or investment advice. That’s not meant to be (just) the standard no investment advice disclaimer but for real - you should try and see what fits you and what’s the best way you can form decisions.
Chart Patterns
Simple website not loaded with tons of graphics and ad trash. Just text and a couple of images showcasing chart patterns. Take a look at triangles and pennants if you want to look smart in crypto-trading chats.

Here it’s not so much about the nitty gritty of technical analysis and more about strategies and methods how to day trade. If you are looking to swing trading altcoins, or even any altcoin trading in shorter timespans, not holding long term - this one will be good for you.
