Another Renko PA system (not finished ye)

Hi
A new idea suddenly occurred to me. It's pretty simple and looks good, so I'm posting it here. Hopefully we can do better.

This is a Renko chart with fractal indi.

As a fractal tells you, you can see higher highs, lower lows, and so on.
I think we can use it for wave trading.

What happens if we only care about the last 3 fractals?
1: Upper fractal, lower fractal, upper fractal.
2: Lower fractal, upper fractal, lower fractal.
3: Probably something else.
In case 1, if the second upper fractal is lower than the first, we consider it a downtrend and we sell when the price breaks above the lower fractal.
Case 2 is the same as Case 1, but we buy.
For case 3, we do nothing.

This is the case2.

When does it close?

So, when will it close? I don't know the best answer. Close however you like and share your closure with kindness.
