If you wait to enter or exit at "the exact moment," you will never make any move. Buy or sell according to a price target (realistic or ambitious) and that's it.

A question: WHAT is the exact moment to sell the currency and the exact moment to buy it? When to know? Look at the graphs for the MINIMUM and MAXIMUM so as not to lose it or should I leave it there and exceed the value I bought it for. For example, I BOUGHT the sol. at 204 it is already at 215, but there on the graph it is MINIMUM 213, maximum 215 in 24 hours. What does this say? Can any professional help me?
