Yes some of the Technical Analysis don't always work they are just guides of the possible things that may happen based on existing evidences but we really don't know what will happen or maybe there are some wrong things you did or missed when you tried to buy or maybe you read it wrong still we should always be ready on what will happen since market is really unpredictable.
It turns out that technical analysis does not always work, and not everyone is able to do it efficiently. Can we then say that trading in some cases is conducted only on the basis of luck? It's just that sometimes trading on crypto exchanges reminds me of playing roulette or dice.
