oh i c. look at what you want to add in ur example. then in real terms consider at what price do you get the 300,000 shares. then, at what price would u sell them.

you'll note the percentage is not 15% and likely more negligible than u might think. your buying will likely push up the price. selling will push down the price. 800 shares traded at $072. use that price action as an exercise to back-test. a real world example can better illustrate

so that's what i mean by 'realistic', 'real terms' and 'wasted energy'.

but now i also understand your pov better too. thnx for the clarity
