Picking another moment to enter a trade will always give another result in the end, except if by coincidence the price would be exactly the same. This proofs that theoretically a trader can influence the result. I write clearly CAN. You say it is impossible.
It shows that flipping coins is different from trading. So your statement is completely wrong.
If you flip a coin now or in 1 hour or in 1 week, the result will be the same.
If you enter a trade now or in 1 hour or in 1 week, the result will be NOT the same.
I cannot help it that you cannot understand this. Maybe you were not in the first row when God distributed skill to people. I will try to put my logic in a very simple , easy to understand sample:
We both can choose when to buy, 1 time only, the ES, but we should sell it again at 16:00
According to you nobody can influence the result.
- I buy at 8:30 when price is 2000 because I think the price is low and will go up.
- You buy at 10:30 when the price is at 2002.
- We sell at 16:00 and price is at 2007. I made 7 points profit, you made 5 points profit. So my decision to buy at 8:30 influenced the result because I made 2 points more than you. So I did influence the result.
Now we will flip the coin. We will flip it 1 time and we both can choose when: 8:30 or 10:30, or even 16:00
No matter when we flip the coin the result will always be the same. So here you cannot influence the result. My choice of timing will give the same result as your choice of timing. Time cannot change the probabilities.
I know it will still be impossible for you to understand, but at least other people reading this might understand it.
