I modified this indicator a little bit.
1. To turn on or off the comment in the upper left corner.
2. You can plot the trend lines as regular lines or dotted lines.
For dotted lines, you can choose any symbol such as square, diamond, stars, etc...
It's mix and match. If you move the mouse over each trend line, it will tell you which line is which.
//FATL - fast adaptive trend line
//SATL - slow adaptive trend line
//RFTL - reference fast trend line
//RSTL - reference slow trend line
