The whole market was in turmoil yesterday. I was able to change out stocks and rebalance fine which, is 100% working and executing orders. If it takes time there’s a reason for it. Different markets open whilst others closed etc
Pies use market orders which almost always trigger in less than a few minutes. The more volatile the stock the harder for the pie to find a match. Same would happen if you sold the shares outside a pie.
The stocks from my pie were not volatile at all yesterday. The pie just didn’t process. I would say on the contrary. The tale is that I was unable to sell before the market closed so go figure!
