Plot a value also for the last (current) bar

Question

I'm plotting a line that changes its value every month:

lastmonth_high = security(syminfo.tickerid, "M", high) 
plot(lastmonth_high, color=lastmonth_high != lastmonth_high[1] ? na : color.blue, style=plot.style_line, linewidth=3)

This way it plots no value at the actual bar. How can I extend the line one bar to the right ?

Answer 1

try this

lastmonth_high = security(syminfo.tickerid, "M", high, lookahead = barmerge.lookahead_on)
plot(lastmonth_high, color=lastmonth_high != lastmonth_high[1] ? na : color.blue, style=plot.style_line, linewidth=3)
