Simple Monthly Support and Resistance Analysis

Sometimes less is more. Using simple methods for drawing my monthly support and resistance has been a great improvement to my trading. I cannot post all my trades and analysis, but here is what I have been looking at primarily while being long Yen since the start of this trend. No complex patterns, indicators or fundamental knowledge is needed.
I am short this pair, and looking for price to head towards 100 area.
