Hornswaggle, lol.easymoney, I think you're thinking too hard and making this more complex than it is.
How much simpler could it be to simply show
the A anchor point,
the B anchor point,
the C anchor point.
Specifics are important.
e.g.Which past high? Which past low?
What triggered your entry?
Why did you select that percent as your target?
For clarity, why not show us so we can be sure that we understand what your are demonstrating?
Now, if you simply don't want to release those simple simple details, that's your prerogative, but it doesn't support your stated opinion that it takes less thought than a simple diagram.
