ETH Preparing for Breakout?

Hi dear traders! In the 4 hr chart, you can see my prediction about the price of ETH. I'm expecting to see a confirmation of a bullish flag very similar to the last bulish flag.

How much room does it have to run? The theory said that shoud be similar to the vertical measure of the base of the ascending triangle.

I'll wait to buy until it touch the support line, and after the break out.

I'll be happy to hear your feedback. Safe trade!
