Extremely poor price on rebalance market execution

Hello, I recently rebalanced one of my pies and it reduced my position in 3ARK. Unfortunately for me, the execution of this trade happened immediately at UK LSE market open and the avg price caught was significantly below the NBBO.

Two orders as part of same sale, both executed at 08:00. One executed at p2,535.9 and the other at p3,185.4. That’s over a 25% difference - extremely brutal.

I suspect this happened because the order executed immediately at market open and just hit an illiquid order-book. Is there any way the pie rebalance mechanism could have some common-sense discretion, or perhaps a way to schedule a rebalance at a specific time?

Pies are basically useless for me if they can’t apply even slight discretion when trading close

The real question is why are you holding and rebalancing an illiquid, 3x leveraged position in a pie. An instrument that is quite literally designed to be held for no longer than a day.
