Debugging Scripts in ThinkOrSwim

[johnwood34]

I'm having an issue with a small portion of this script. Can anyone help me with it? Providing a snapshot of my screen as to what i'm being prompted with...

Here are some suggestions when debugging:
1. ThinkScript shows the LAST error
2. You must scroll up through the errors to see the FIRST error

In this case: there plots that don't exist
Open Inspector and it will display the real plot names.
Click on the real ones.

FYI:
You must have your cursor on the ToS function that is showing the error
or type in the function being referenced and the inspector will provide all the settings

And then go on to the next error.


Here is the corrected code:

declare upper;

# Inputs
input fastSMA_length = 50; # Fast moving average (50-period)
input slowSMA_length = 200; # Slow moving average (200-period)
input rsi_length = 14; # RSI period (14-period)
input macd_shortLength = 12; # MACD short period (12) -- Updated to 12
input macd_longLength = 26; # MACD long period (26) -- Updated to 26
input macd_signalLength = 9; # MACD signal period (9) -- Updated to 9
input volumeLength = 20; # Volume average period (20)
input overbought = 70; # Overbought level for RSI (70)
input oversold = 30; # Oversold level for RSI (30)
input showSignals = yes; # Toggle to show signals

# Calculate Moving Averages
def fastSMA = Average(close, fastSMA_length); # Fast SMA (50-period)
def slowSMA = Average(close, slowSMA_length); # Slow SMA (200-period)

# Calculate RSI
def rsi = RSI(rsi_length);

# Calculate MACD
def macdValue = MACD(fastLength = macd_shortLength, slowLength = macd_longLength, MACDLength = macd_signalLength).value;
def signalLine = MACD(fastLength = macd_shortLength, slowLength = macd_longLength, MACDLength = macd_signalLength).Avg;

# Calculate Volume
def avgVolume = Average(volume, volumeLength);
def highVolume = volume > avgVolume; # High volume signal

# Bullish and Bearish Engulfing Candlestick Patterns (simplified)
def bullishEngulfing = close > open and close[1] < open[1] and close > open[1] and open < close[1];
def bearishEngulfing = open > close and open[1] < close[1] and open > close[1] and close < open[1];

# Buy Signal Logic
def buySignal = (fastSMA crosses above slowSMA) and (rsi < oversold) and (macdValue crosses above signalLine) and highVolume and bullishEngulfing;

# Sell Signal Logic
def sellSignal = (fastSMA crosses below slowSMA) and (rsi > overbought) and (macdValue crosses below signalLine) and highVolume and bearishEngulfing;

# Plot Buy and Sell Signals
plot BuySignalPlot = if showSignals and buySignal then low - 0.5 else Double.NaN;
BuySignalPlot.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
BuySignalPlot.SetDefaultColor(Color.GREEN);
BuySignalPlot.SetLineWeight(3);

plot SellSignalPlot = if showSignals and sellSignal then high + 0.5 else Double.NaN;
SellSignalPlot.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
SellSignalPlot.SetDefaultColor(Color.RED);
SellSignalPlot.SetLineWeight(3);

Thank you! Now how do I delete my original post?

chatGPT creates many errors

Here are some suggestions when debugging:
1. ThinkScript shows the LAST error
2. You must scroll up through the errors to see the FIRST error

In this case: chatGPT invented plots that don't exist
Open Inspector and it will display the real plot names.
Click on the real ones.

And then go on to the next error.
chatGPT creates a lot of errors.

i have never used the inspector.
i keep a few tabs open in browser, to several thinkscript function pages.

how did you get it to show a list of plots?
it just shows me a keypad of numbers.

oops....
You are correct.
I left out a step...
You must have your cursor on the ToS function that is showing the error
