BTCUSD how to make 90 degree relations show up

Some people were wondering how to set the scale close to perfect to make 90 degree relations show up . This is how. Use the rectangle tool in combination with the magnet tool. Zoom in when you do it. The 2 red brush marks are where the rectangle tool is anchored from. After those points are anchored turn off the magnet tool. 33 down and 57 up= a perfect 90 setting. There are 2 right angle relations showing. Notice the 23 and 11 are almost half also. The fib channel can be set from 1 division to 10 divisions. I used 9 on this chart because they fit the data best.
