Time based, visual trailing stop - Script request

Hey FF, I've been wanting something like this for a while for my manual trading, was wondering if its possible to write a script that would modify an open order based on lines drawn in a chart.

See pic attached.

can not see it, there is no image at all

Yes is possible.
(maybe when I have more time)

Try this.
It is not bombproof!

As you have not specified EXACTLY what you want this script will / should adjust the SL to the price of the line at the last candle time.

You MUST name your line "m123"

It should still work if line is too close to price and set to min SL distance but just use sensible line position.

If line is above price it assumes you have short position and vv.
Will change ALL orders for that symbol

HTH
