Thanks for your note.
If you are wanting to use a negative tick offset, you could set the 'Offset' field to use 'Ticks' and then specify a value of say "-10" to set the offset to -10 ticks.
When it comes to using user-defined variables, you would need to define the variable value as a negative value, such as setting MovementDownTrigger = -10 in the script, then use the variable for your tick offset.
If this is a user-defined input, you should set the user-defined input's 'Min' value to a negative value when creating the input on the Inputs and Variables screen and set the input's 'Default' value to a negative number like '-10'. That user-defined input could then be used for your tick offset field. Note the 'Min' values defines the minimum value the input can be set to.
Let me know if I may assist further.
