Technical analysis is very important to succeed in trading cryptocurrencies. I think the some tools that are used for technical analysis are
1. On-balance volume indicator (OBV) to measure the positive and negative flow of volume in security over time.
2. One of the most commonly used indicators to determine the money flow  in and out of a security is the accumulation line (A/D line)
3. The Average direction index (ADX) is a trend indicator used to measure the strength and momentum of a trend. When the ADX is above 40, the trend is considered to have a lot of directional strength, either up or down, depending on the direction the price is moving.
4. Relative Strength Index (RSI) compares the magnitude of recent gains to recent losses to see if an asset is oversold or overbought.
