Measure the distance from entry to stop against the distance from entry to target, and read the ratio between them.

How it works: ratio = distance from entry to target / distance from entry to stop
Enter three prices and the page reports how far the stop is, how far the target is, and the ratio between them. A ratio of 2 means the target is twice as far away as the stop.
The ratio is geometry, not a forecast. It says nothing about how likely either price is to be reached first, and a wide target is easy to draw and hard to hit. What it does tell you is how often a plan has to be right to break even before costs: at 1 to 2, one trade in three.
A stop on the wrong side of entry is refused rather than given a ratio, because that is a typing mistake and a number would hide it.

Questions
What ratio should I use?
There is no number that is right for everyone, and a higher ratio is not automatically better because targets further away are reached less often. The ratio only matters alongside how often a plan actually reaches its target.
How does the page know if it is long or short?
From the target. A target above entry is a long, a target below it is a short, and the stop has to sit on the other side of entry or the numbers are refused.
Should I count the spread?
It is worth adding, particularly on tight stops. The spread widens the real distance to your stop and shortens the real distance to your target.
