extend

The extend namespace provides constants that control how lines are extended beyond their start and end points. These constants are used with line.new() and line.set_extend() to specify the extension direction.

Quick Example 

from pynecore.lib import script, line, extend, close, bar_index, ta

@script.indicator(title="Trend Line with Extension", overlay=True)
def main():
    if ta.crossover(close, ta.sma(close, 20)):
        ln = line.new(bar_index, close, bar_index + 1, close, extend=extend.right)

Constants

ConstantDescription
extend.bothExtend the line in both directions (left and right)
extend.leftExtend the line to the left beyond the start point
extend.noneDo not extend the line (default behavior)
