RSI Support/Resistance Zones

Here you go:

declare lower;
input length = 14;
input over_Bought = 70;
input over_Sold = 30;
input price = close;
input averageType = AverageType.WILDERS;
input showBreakoutSignals = no;
plot rsi = RSI(length, over_Bought, over_Sold, price, averageType, showBreakoutSignals).RSI;
rsi.DefineColor("OverBought", GetColor(5));
rsi.DefineColor("Normal", GetColor(7));
rsi.DefineColor("OverSold", GetColor(1));
rsi.AssignValueColor(if rsi > over_Bought then rsi.color("OverBought") else if rsi < over_Sold then rsi.color("OverSold") else rsi.color("Normal"));
DefineGlobalColor("High Bearish", Color.RED);
DefineGlobalColor("Low Bearish", Color.RED);
DefineGlobalColor("High Bullish", Color.GREEN);
DefineGlobalColor("Low Bullish", Color.GREEN);
DefineGlobalColor("None", Color.WHITE);
AddCloud(if !IsNaN(close) then 65 else Double.NaN, if !IsNaN(close) then 55 else Double.NaN, GlobalColor("High Bearish"), Color.BLACK);
AddCloud(if !IsNaN(close) then 30 else Double.NaN, if !IsNaN(close) then 20 else Double.NaN, GlobalColor("Low Bearish"), Color.BLACK);
