Which one is the right channel? Red or Yellow?

How do we determinate which one is the correct channel?
Is it the red or the yellow one?

If the correct one is yellow, then the channel has been broken, a signal that we should start considering a short position, meanwhile if the right one is the red one, we could conclude that we are still going up at a steady pace and we would go long.
