I am trying to convert an old script to V5 and get the error below.

zigzag() =>
    _isUp = close >= open
    _isDown = close <= open
    _direction = _isUp[1] and _isDown ? -1 : _isDown[1] and _isUp ? 1 : nz (_direction[1]) 
    _zigzag = _isUp[1] and _isDown and _direction[1] != -1 ? ta.highest(2) : _isDown[1] and _isUp and _direction[1] != 1 ? ta.lowest(2) : na

Undeclared identifier '_direction'

Variable '_direction' is not found in scope 'zigzag', cannot register side effect

What is the problem here? Do you have any recommendations?

Self referencing is not allowed from v3 and above.

You should first define the variable and then use it.

zigzag() =>
    _isUp = close >= open
    _isDown = close <= open
    _direction = 0
    _direction := _isUp[1] and _isDown ? -1 : _isDown[1] and _isUp ? 1 : nz (_direction[1]) 
    _zigzag = _isUp[1] and _isDown and _direction[1] != -1 ? ta.highest(2) : _isDown[1] and _isUp and _direction[1] != 1 ? ta.lowest(2) : na
