Right... that's another serious problem in your strategy here.
You're guessing on things that don't need to be guessed on.
And then you're extrapolating more based on the guess.
You're gonna 100% know what the peak is in advance before trying to guess the bottom.

You need to clear your head of all that nonsense and keep an open mind, or else when the real information presents itself you're going to let the old guesses that have already been proven wrong affect your decision-making.

This is a real thing that happens in trading every cycle.
