Hi all- probably a total newb question, but is there a reason why US orders are executed at 15:00 GMT vs 14:30 (i.e. 9:30 EST when US markets open). Yesterday was the first time i’ve placed an order outside of market trading (what with the US holiday yesterday), so just wondering at what time the order will be priced at (i.e. Friday’s market close price, today’s market open price or the price at 10:00 EST).
Thanks in advance.
