Regardless, I’ve traded for decades and on high-volume stocks (which are the ones you’re likely to trade), putting limit orders in is a waste of effort. For some folks, it’s important to save a few cents. For you, not so much. Different story on penny stock or < 100K/day in volume, but if you’re buying AAPL just put a market order in.
For example buying a LIMIT says the highest price I am willing to pay per share is X. So you can be confident you'll get a price at least equal to or below the limit price.
> the share price is meaningless to me
??? Confused. Do you like buying high and selling low?
For retail order sizes and holding periods, that's probably fine as long as you place orders close to the current price.
