Previous Bar High Low

[johnwood34]

Looking for an indicator the plots only the previous candles high and low, that displays a horizontal line the width of the previous candle's high and low, as well as the current candle. Then once the current candle closes, updates to the previous/current candles, leaving no historic plots. (see attached screen shot)...

def na = double.nan;
def bn = barnumber();
def lastbar = !isnan(close[0]) and isnan(close[-1]);

def hi = if bn == 1 then na
else if lastbar[-1] then high 
else if lastbar then hi[1]
else na;
def lo = if bn == 1 then na
else if lastbar[-1] then low
else if lastbar then lo[1]
else na;

plot zhi = hi;
plot zlo = lo;
zhi.SetDefaultColor(Color.cyan);
zhi.setlineweight(2);
zhi.hidebubble();
zlo.SetDefaultColor(Color.cyan);
zlo.setlineweight(2);
zlo.hidebubble();
