There is a difference between technical analysis and on-chain analysis. Technical analysis is used during trading by looking at crypto charts and corresponding indicators. On-chain analysis, however,  is used to look at blockchain data to gain insight regarding the factors that drive a change in price. This knowledge can then be used to predict future market movements. Because the blockchain is an open and transparent database, all these factors can be easily observed. Do you want to learn how to do this? Then have a look at the free on-chain analysis video.
