ii) Either you can wait for the 1hr range to complete as per the lines, may take 2-3days also & Enter the hourly breakout
iii ) If aggressive, entering breakout direction in 15mins & reversing the trade on failure will be ideal
So it depends on what you wish to do.
Seems confusing ? Nope not at all, thats how one should trade, Trade the setup which you have & followed regularly :)
