If this is a flat correction, red wave {c} is likely to re-test wave {a} low at 1.52747.
also be aware that the length of wave {c} of an expanded flat often equals to 1.618 times the length of wave {a} (at 1.4874) OR wave {c} could end beyond the termination point of wave {a} by 0.618 times the length of wave {a} (at 1.4708)
