Upper Level RSI support/resistance

I've been trying to get plots of RSI support/resistance on upper chart similar to this Tradingview study https://www.tradingview.com/script/pnc5rcY3-RSI-Support-Resistance-by-DGT/. If I declare upper; nothing plots. If I drag the study up to price chart it plots but not at correct areas. I had one other version that seemed to plot but was distorting based on zoom levels of current chart. Can anyone help or steer me in correct direction? Much appreciated. Code and picture below:

declare lower;

input length = 14;
input over_Bought = 70;
input highband = 75;
input over_Sold = 30;
input lowband = 25;
input price = close;
input averageType = AverageType.WILDERS;
input showBreakoutSignals = no;

def NetChgAvg = MovingAverage(averageType, price - price[1], length);
def TotChgAvg = MovingAverage(averageType, AbsValue(price - price[1]), length);
def ChgRatio = if TotChgAvg != 0 then NetChgAvg / TotChgAvg else 0;

plot RSI = 50 * (ChgRatio + 1);
plot OverSold = over_Sold;
plot OverBought = over_Bought;
plot UpSignal = if RSI crosses above OverSold then OverSold else Double.NaN;
plot DownSignal = if RSI crosses below OverBought then OverBought else Double.NaN;

UpSignal.SetHiding(!showBreakoutSignals);
DownSignal.SetHiding(!showBreakoutSignals);

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"));
OverSold.SetDefaultColor(GetColor(8));
OverBought.SetDefaultColor(GetColor(8));
UpSignal.SetDefaultColor(Color.UPTICK);
UpSignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
DownSignal.SetDefaultColor(Color.DOWNTICK);
DownSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

# ---------------------------------- Add Cloud_OBOS -----------------

input Cloud_OBOS = yes;

DefineGlobalColor( "OBCloud", color.red);
DefineGlobalColor( "OSCloud", color.green);

def OB1 = over_Bought;
def OB2 = highband;

def OS1 = over_Sold;
def OS2 = lowband;



DefineGlobalColor("Overbought", Color.light_GRAY);

you can't just put a lower study on an upper chart and expect it to conform to the range of price bars. it is hard coded to plot numbers that are between 0 and 100.

this part that was added at the end, is setting numbers for cloud levels.
def OB1 = over_Bought;
def OB2 = highband;
def OS1 = over_Sold;
def OS2 = lowband;

you would have to compare the rsi to these levels. if it crosses one of them, then assign a price level to be plotted or used in a cloud.

here is an upper , that is somewhat converted from the pine code.

Thank you @halcyonguy for the help!
 
@GoLo , if you are looking to identify potential S/R levels, probably ADX is a better tool than RSI. check when those marked signals appear, which represent peaks of trends. you might add code to point the price level it happens

I am not familiar with it. But do you think that there is no mistake here in your code? Thanks for sharing

Code:
plot Kick = Kicko[0];
plot KickL = Kicko[0];
