I just compared BNS and IRXY trans Norm for the recent 22 days as Fig.1

• A very long decreasing trend can be recognized in IRXY_NORM. However, it could be recovered by some adjustments as -19 days, -8 days, and -6 days.
• The BNS reduction around -7 days seems to correlate with the IRXY trans reduction.

Do you find any more characteristic points?
