Question for those who are knowledgeable about stock investing.
In papertrade, with a market buy order of special buy indication of aggressive buying before the opening for individual stocks,
you can easily make a profit by buying cheaper than the opening price.
In actual trades including accounts other than papertrade, with a market order of special buy indication before the opening,
is it impossible to execute a buy order cheaper than the opening price as with papertrades?
-> In other words, in actual trading, is it the norm for a market buy order to be executed at the opening price after the special buy indication before the opening ends?
Is this the basic principle?
I would definitely like to receive your guidance.
