Possible Wave 5 to follow completion of Wave 4 (Flat)

Following on from my previous post, wave C completed in 5 waves at the trend line as expected. I am now expecting to see a wave 5. However once again the risk:reward is not at least 3:1 so based on my trading system I will not be entering this trade. If I was entering, I would enter on a break of a horizontal line drawn from the beginning of wave 4 of C with my stop at the wave C extreme.
