I am a total newbie to all this.
How near can I get to buying a stock (etc) at the "open" price, and selling it at the "close" price?
I have been using end-of-day data to develop a strategy, and given that the data contains "open" and "close" prices, my strategy is based on realising these prices.
As I understand it, the offers to sell, that remain outstanding once the "open" price is determined, will generally be above the open price, meaning that I won't actually be able to buy a stock at this price. So I'm curious as to how near to the "open" price I could actually buy. E.g. is it reasonable to assume I could buy for "open" plus one tick?
Thanks in advance for any answers,
