EURUSD 240 Reflections and Right angles

The chart is on SCALE LOCK so you can move it around easily. Check back further for lots more angle relationships.
I used the rectangle tool (paintbrush toolbox) to make right angles from 2 anchored points. I also used the new angle tool. It now has coordinate and angle inputs (trendline toolbox. Both on left hand side of screen.
The chart was set up by making the angles in the filled in rectangle area perfect right angles. After that, reflections and right angles started showing up.
That's how much difference SCALING a chart makes. How is this any good to prediction? If you know reflections are common you can use the reflected angle to know approximately how the angle top or bottom will conclude. This is only one of many ideas you could combine for prediction. Others are arcs, channels, horizontal fib levels,curved trendlines or straight ones, etc.
