If you belive -ve rates are a thing then this trade is not for you. If rates have hit all-time lows then this Wyckoff topping pattern on the 10 year T-note weekly chart makes fundamental sense. Technically it has a lot of work to do to the downside to confirm. Typically Wyckoff tops with Upthrust after distribution (UTAD) resolve swiftly to the downside. Noting that the holding costs are significant for large trade size.
