What is the most accurate buy and sell indicator?

In the realm of cryptocurrency and finance, the quest for the holy grail of buy and sell indicators is ever-present. So, I must ask, what is the most accurate buy and sell indicator in today's volatile markets? Is it the Moving Average Convergence Divergence (MACD), which analyzes the relationship between two moving averages? Or perhaps the Relative Strength Index (RSI), which measures the speed and change of price movements? Could it be the Stochastic Oscillator, which compares a security's closing price to its price range over a period of time? The search for the perfect indicator often leads to mixed results, as each has its own strengths and weaknesses. So, what indicator do you believe provides the most accurate signals for buying and selling in today's cryptocurrency landscape?
