I placed a buy order but I would like to get my money back. What should I do?
Unfortunately, if your buy order has been successfully placed, you can no longer cancel it. However, you can try to immediately place a sell order once the buy order is fully processed.
Both the completion of your buy order and the placing of a sell order will go through the standard processing days, so you will not be able to get your money back immediately.
