You can use technical analysis (TA) in your spot trade crypto strategy. TA involves analyzing and interpreting past price movements and trading volumes to predict future price changes. It can be helpful for trading strategy: identifying entry and exit points, establishing Take-Profit (TP) and Stop-Loss (SL), and determining overall market trends.
TA is not an infallible tool; it can only sometimes predict future price movements accurately. Combining TA with fundamental analysis (FA) is also recommended for a more comprehensive market view.
