Can't draw a line (line2) from the open bar where line1 ends... line2 starts at the right bar, but the starting point is not the same - you need to get open What I do wrong. The presented script is stable, but not correct...

//@version=6
indicator('Проба-2', overlay = true)

var BIG_NUMBER = 999999999 // safely bigger than any bar_index

                      math.abs(open[1] - close[1]) > math.abs(open[2] - close[2]) and
                      low < open[1]

twocandlesbody1 = open[1] < close[1] and open > close and low < open[1]

enter image description here

I tried to do the calculation of the entry point for line2 through the difference open [N _ tiker] - open, tried to apply the logic of finding the starting point through logical manipulations - such as if the first line ended, then the second line from open... begins. None of this worked - the script gave an error during testing.I also tried options with ta.barssciens and ta.valuewhen - but this did nothing at all...
