A descending triangle as wave B?

The confusing corrections could be forming something else which I couldn't guessed !

Below picture indicates Major b wave as descending triangle.

This could be surely it, if eur/usd falls around 1.22600 area.
Above pic.

Yellow wave A= double zig-zag+double irregulars+double zig-zag

white a = double zig-zag ( end of point a marked 50% retracement of yellow A)
white b = double zig-zag
white c = double zig-zag
white d= double zig-zag ( post below)

Here, if its going to be descending triangle than white a is the lowest point in the tri angle.
white e could end around 1.22600, however a break above 1.23700 indicates fallacy of this probability.

But looking at above picture and guessing where wave B could be..it surely triangle, shallow zig-zags in a bounded channels
