this library can draw typical liquidation lines, which can be called e.g. by indicator signals
You can see the default implementation in the lower part of the code, starting with RUNTIME
Don't forget to increase max lines to 500 in your script.
It can look like this screenshot here, with only minor changes to your executing script.
The base is the same

Runtime Demo update, no function changes

版本注释

This update mainly does 2 things:

Deleting lines which are just wasting free lines (selectable min length, -1 to disable (standard value in the function)

Speeding up the runtime by filtering doublegets inside the liqline_update by a additional if branche for preselection
gets are slow, so why calculate when not needed.

small fixes:
typo on bollinger block always requesting BB Nr. 1 instead of 1 2 3

v3

Added:
f_getbartime()
this does give you the average time per bar from a sample of 100 bars

Updated:
f_liqline_update(_Liqui_Line, _killonlowhigh, _minlength, _timeperbar)
  Parameters:
    _Liqui_Line (Liquidationline[])
    _killonlowhigh (bool)
    _minlength (int)
    _timeperbar (float)
minlength and timeperbar is added but not needed to function correctly.
aware this adds some repainting behavior as it deletes lines after detecting
