I prefer to rely on events that happen in the real world rather than on charts drawn on the basis of a continuation of patterns. Like the miners' ban in China last year, which was not foreseen in any technical analysis or predictive model, also the reduction of liquidity by central banks, or the cascading liquidation of leveraged positions as we have seen recently. All this is much more important than standing in front of a blackboard and drawing future lines based on the supposed regularities you observe in the past.
Your point of view is somewhat logical, this is what I think too. Indicators and charts often fail to predict the future, especially when there are important events that change the course of events such as the Corona virus, interest rate hike by the US Federal Reserve or the ban on mining in China, In all of these cases there were major influences that led to the failure of all predictions, so I believe that indicators, charts and technical analysis are only useful in cases where things are going naturally without any unexpected influences.
