That’s actually incorrect. Sells on GME were blocked on the 30th at market open. I intended to sell at open to cash in on the pre-market. However I ended up having to queue my order, which didn’t confirm till around 3:30, by which time GME had dropped $100 or so a share.
I understand the FX provider being down preventing the conversion of USD to GBP, but as far as I am aware (and as Freetrade communicated) the trading partner hadn’t blocked orders, Freetrade had.
