ChatGPT, BARD, Other AI Scripts Which Can't Be Used In ThinkOrSwim

[MerryDay]

90% of the members attempting chatGPT scripting; do not provide good detailed specifications.

Members know what end result that they want but lack the ability to tell chatGPT, the step-by-step logic required to code a script to achieve that end result.
This results in chatGPT providing poor code.

Here is a video on how to successfully have chatGPT create functional scripts.

The above video, explains the basics of providing good specifications to AI which results in better scripts.

Lines at the last 3 highest volume vwap level within the last 52 weeks.
This is what i got from ChatGPT. Price is shown but no line is drawn on the chart. This is for just one line for the last highest vwap level.. I need it to draw 3 lines for the last 3 highest vwap level, add a number on each line in ascending order. Thank you for any help.



input lookbackPeriod = 52; # Lookback period in weeks

# Calculate the number of bars in the lookback period
def barsInPeriod = lookbackPeriod * 5;

# Find the highest volume day within the lookback period
def highestVolumeDay = Highest(volume, barsInPeriod);

# Calculate VWAP for the highest volume day
def vwapHighestVolumeDay = if volume == highestVolumeDay then reference VWAP() else Double.NaN;

# Plot horizontal line at the VWAP level of the highest volume day
plot VWAPLine = if !IsNaN(vwapHighestVolumeDay) then vwapHighestVolumeDay else Double.NaN;
VWAPLine.SetDefaultColor(Color.BLUE);
VWAPLine.SetLineWeight(1);

Please help me find the error in this code. Thank you.
Goal of the code is to Scan for a Moving Average crossing above another moving average AFTER A SPECIFIED NUMBER OF DAYS (BARS)

# User inputs
input fastLength = 8;
input slowLength = 20;
input crossPeriod = 20;

# Calculate moving averages
def fastEMA = ExpAverage(close, fastLength);
def slowEMA = ExpAverage(close, slowLength);

# Check for crossover and if fastEMA has been below slowEMA for at least 5 days
def belowSlowEMA = fastEMA < slowEMA;
def belowSlowEMAPeriod = Sum(belowSlowEMA, crossPeriod) == crossPeriod;
def cross = if (fastEMA > slowEMA and belowSlowEMAPeriod) then 1 else 0;

# Plot the crossover signal
plot scanSignal = cross;

reply to #240
the cross = line is wrong,
it should be looking at the previous value of belowSlowEMAPeriod, not the current value.
i added an offset to read a value from 1 bar ago.

replace your code line with this one,
def cross = if (fastEMA > slowEMA and belowSlowEMAPeriod[1] ) then 1 else 0;
