I think very few people know in advance when the market will correct and the price will go down. The crypto market is always full of surprises. For some experienced traders, it is possible that they will be able to guess based on the signals that they have gathered through many trades. When the price is too high for a while, there may be a correction in the following days, but it is all guesswork, no one can know exactly what will happen in the future.
For TA's then yes but talking literally then it doesnt exist because there would be no human on this world does able to know on what future looks like thats
why this is on self research and analysis when making out some presumptions or speculations on where the price could possibly able to go.
When we do speak about correction then this is something that hard to know because it all varies with the community or market sentiment
whether it is been influenced by Fud or any fundamentals.
