the fact that the market price shifts lower when buying or higher when selling - is a law of exchange trading. You yourself influence the market with your trade. The meaning of the exchange order book

Yesterday I sold BTC for about 86
Today I want to buy on the dip. I haven't bought yet, I decided to test a new strategy))

The thing is, I almost always guess right with selling, and almost never guess right with buying. After my purchase, the price always drops even more🙈
A possible solution to the problem is to buy in parts, in several stages, to catch the lowest price.

For now, I've decided that my strong desire to buy is a clear signal that it's too early🙈😂
Here I am waiting, it seems I missed the price of 82,000 🤷🏻‍♀️
So what to do? How do you make decisions, what signals do you use?
