Trailing stop along Mobile average

Hello ATAS Development Team :-)
Could it be possible to create a trailing stop which would follow the level of a mobile average?

In a perfect world this could be changed “on-the-fly” and a normal stop could become a trailing stop using either a mobile average or any line that could be drawn, eventually through manual process. Just by clicking/selecting the Mobile Average or the line on the chart.

The manually draw line ruling option would also allow, for example to close the position at the end of the line which would, on a time-based market display, therefore create a time-limited position.

I hope at least the trailing stop along mobile average will come.
It would be awesome stuff!

Many thanks for your time and dedication.
