There was a 2 wave pattern from a to b, and then a break down. Wouldn't tha constitute a finalized b?

abc waves should be equivalent to 12345 in terms of size of retracement. I suggest you use Fib levels.

Could be a triangle as well; (c) would than between 1.295 and 1.31 and (d) and (e) would follow. In any case, if (c) should develop as sketched out above, it would have to have an impulse structure consisting of 5 waves. If it is a mere 3 wave move, it'll be a triangle.

The downtrend will determine it. The triangle would be too big imo.
