Question:
Am I permitted to place a stock order before Yom Tov that will be executed on Yom Tov itself?
Basically, the money in my account will be used to purchase the stock on Yom Tov but the purchase order will be done the day before.
Answer:
Ordering a machine before Yom Tov is permitted however the actual buying of an itm on Yom Tov is incorrect, and should not be done. Please see the following post where a similar question was discussed. https://dinonline.org/2011/04/27/purchased-stocks-on-yom-tom/
Have a good Yom Tov
