The advantage of a pinpoint entry is that when your unrealized profit reaches three times your stop-loss amount, you can close enough of the position to cover the amount you could lose at the stop. That way, even if your stop is hit, you don’t lose money—you can hold the position without risk. For example, if the distance between your entry and stop-loss levels means you’d lose 10U, then when your unrealized profit reaches 30U, reduce your position by 25%. You’re not closing out 10U of profit; you’re reducing the position by 25%. After doing so, your unrealized profit will be 7.5U, and the amount you could lose at the stop will also be 7.5U. You can then hold the position without risk until it reaches your target. Otherwise, watching unrealized profit turn into a loss and then hit your stop can easily make you lose composure.
