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.

halcyonguy , The time code is not working correctly with Gold Futures, what could it be?

reply to 201 , 192
https://usethinkscript.com/threads/...used-in-thinkorswim.13822/page-10#post-134251

you didn't say anything about futures in your post.
it seems like RegularTradingStart(GetYYYYMMDD()) doesn't read the correct value with futures. i'm not sure why, i don't trade futures. i loaded the built in futures watchlist, and looked at some symbols. turn on extended hours.
i added this to put a colored bubble at the start and end of the trading period. it doesn't seem to work.
it does work with normal stocks, 9;30 to 4pm

Code:
def start = gettime() == RegularTradingStart(GetYYYYMMDD()) + 1;
def end = gettime() == RegularTradingend(GetYYYYMMDD()) + 1;

addchartbubble(1, low,
start + " S\n" +
end + " E"
, (if start then color.green else if end then color.red else color.gray), no);

No, it won't work in the strategy tab.
The strategy tab is ONLY for scripts with ADDORDER statements used in backtesting.

You did not include a screen grab, therefore it is not possible to say where you went astray.
1. Many times, it is a cut & paste error. Consider re-pasting the script into your study tab.
2. Click on the script in the study tab, scroll to the bottom, you will see your errors.
3. If you are still having issues, cut & paste your script into your post, so contributors can review it for syntax errors.

go back and edit your post,

tell us what it does on a time chart and what it doesn't do on a tick chart.

never say 'it doesn't work'.
i'm not going to load it on different charts and guess at what the issue might be.
 
Hello team, I'm new to thinkscript world, so I asked ChatGPT: Write a ThinkScript for AddLabel for CurrentBar volume, with change LabelColor to Green when volume of the CurrentBar is greater than or equal to 100,000.

ChatGPT:

declare lower;

# Define the volume of the current bar
def currentVolume = volume;

# Define label color based on volume
def labelColor = if currentVolume >= 100000 then Color.GREEN else Color.GRAY;

# Add a label displaying the volume of the current bar
AddLabel(yes, "Current Bar Volume: " + AsText(currentVolume), labelColor);


---but the script generated following errors:
Expected double at 7:5
Incompatible parameter: labelColor at 7:5
Expected class com.devexperts.tos.thinkscript.data.CustomColor at 10:1
Expected double at 7:5
Incompatible parameter: labelColor at 7:5
Expected class com.devexperts.tos.thinkscript.data.CustomColor at 10:1

I pasted the errors to ChatGPT, but it gave me another set of script with more errors, I'm sure this is an easy fix. Can you assist. Thanks in advanced guys.

reply to 211

can't set a color to a variable.
have to put the color if-then formula inside the label.

don't need astext(currentVolume). it actually adds .00 to end of number
asprice() formats number with no commas
just use currentVolume as it is.

i removed declare lower, so it will appear in the volume chart.
need to turn on volume sub graph

reply to #208

thanks for reposting. i don't use tick charts so was hoping for more clues, because i had none.
after loading the study, it shows a ! in the top left corner. clicking on it says
can't use secondary periods less than 1 day on tick charts.
92P0Ls7.png


unfortunately, this doesn't help. TOS is good at creating useless error messages.

so... when something doesn't work, try simple things, then simplify it.

i tried changing the symbols. nothing.
i started at the end and started disabling code lines.

when i disabled this line
price1 = close(symbol1);
then something plotted

so i guess , tick charts don't like reading data from a different symbol...?


maybe @MerryDay can explain why this happens

Hello everyone,
I am no expert in script languages and converting languages into others. The goal to create this seemed simple until I was staying up all night(s). Maybe I'm going about it the wrong way thinking I can do it all by myself.
I'm trying to recreate an indicator I saw on TradingView and convert it into ThinkScript.

My definition: The indicator takes the company's EPS TTM and you multiply the EPS TTM by 15 (PE Ratio) to calculate the market price per share at 15 times earnings.

I do not know if he birthed this idea but Peter Lynch introduced me to idea and in all of his books that I have display that indicator overlapping the current trading price.

I've completed about one-third of the indicator and I am hoping that someone on these forums would help guide me to the finish line. Please, Thank you.

Concept: https://www.gurufocus.com/news/1471569/behind-the-numbers-peter-lynch-and-fair-value

Original code: https://www.tradingview.com/script/Y5bvwFfr-Peter-Lynch-Value/

Current code (Formatted by ChatGPT):
# Calculate Earnings Per Share (EPS) using financial data
def EPS = EarningsPerShareTTM();

#PERatio = input(15, title="P/E Ratio", step=1)
def PERatio = close / EarningsPerShareTTM();
input PE = 15;

# Calculate Fair Price based on EPS and P/E Ratio
#fairprice = EPS > 0 ? PERatio * EPS : na
#plot(fairprice, color=color.green)

# Calculate Earnings Estimate for the fiscal year
#earningestimate = financial(syminfo.tickerid, "EARNINGS_ESTIMATE", "FY")

# Calculate Fair Price Estimate based on Earnings Estimate and P/E Ratio
#fairpriceestimate = earningestimate > 0 ? PERatio * earningestimate : na

# Plot fairprice and fairpriceestimate on the chart.

Why some scripts and some syntax works on tick charts and some don't; is one of those mysteries of the ages.

Support's canned answer:
The core of the ToS app is based on time-based charts. Tick Charts were introduced to provide real-time price action, however support of custom studies is limited.

The forum's canned answer:
We know that scripts that have any time-based calculations will, by default, not work on tick / range/ renko charts.
Beyond that, what works and doesn't work tends to be a crap shoot. It should be noted that members have reported having sporadic success with running custom studies on tick charts with extended hours enabled.


Hope this helps.

I have been stalking this site for a while and took the leap in writing my first scanner code.

I have looked at posts about extended hours here but did not find any that adds both premarket and post market. I decided to write one.

My objective is to add up yesterday's post market and today's premarket volume to identify stocks that have volume greater than day before. I would run this scanner during post market and premarket.

I tested this code on the charts and found it to be working as expected but the scanner doesn't seem to produce the desired results. I am getting results for all stocks with extended hour volume instead of just ones with volume greater than day before. Any pointers in the right direction will be extremely helpful.


Code:
## Trading day for stock market cycles betweeen Pre (04:00-09:29EST), Regular (09:30-03:59EST) and Post trading hours (04:00-08:00)
### On July 3rd, Black Friday and December 24th, regular is (09:30-12:59EST) and post is (01:00-05:00EST) .
### Thinkorswim can have zero or more bars for Pre and post hours based on trades. There are missing bars during regular trading hour

def day = GetDay();

Hey everyone, I'm in the process of teaching myself ThinkScript and figured it'd be helpful to use ChatGPT (version 4) as a kind of virtual tutor. I asked it a simple question about how to add arrows to a chart and this is the answer it gave me:
In ThinkScript, you can add arrows with text on your charts to highlight specific conditions or signals. Typically, you'd use this feature to mark important points on the price chart, like potential buy or sell signals. Here’s how you can do it:

Adding Arrows in ThinkScript​

To add arrows, you'll use the AddChartBubble or AddChartArrow function in your script. However, it's important to note that while you can add text labels to chart bubbles, arrows themselves cannot directly display text beside them. You'd typically use arrows to point out specific price points and use bubbles to add explanatory text.

Here's a basic example of how to use both:
Code:
script ShowSignal {
    input condition = yes;
    input price = close;
    input text = "Signal";
    def showBubble = condition;
    
    # Add arrow pointing up for a buy signal
    AddChartArrow(condition, price, "Up", Color.GREEN, yes);
    
    # Add text bubble near the arrow
    AddChartBubble(showBubble, price, text, Color.GREEN, yes);
}

# Example usage
ShowSignal(condition = close crosses above SMA(close, 20), price = low, text = "Buy Signal");

As far as I can tell however, the AddChartArrow function does not exist in ThinkScript and never has! Is this a legit LLM hallucination?

Thanks
 
Hello everyone,
I am no expert in script languages and converting languages into others. The goal to create this seemed simple until I was staying up all night(s). Maybe I'm going about it the wrong way thinking I can do it all by myself.
I'm trying to recreate an indicator I saw on TradingView and convert it into ThinkScript.

My definition: The indicator takes the company's EPS TTM and you multiply the EPS TTM by 15 (PE Ratio) to calculate the market price per share at 15 times earnings.

I do not know if he birthed this idea but Peter Lynch introduced me to idea and in all of his books that I have display that indicator overlapping the current trading price.

I've completed about one-third of the indicator and I am hoping that someone on these forums would help guide me to the finish line. Please, Thank you.

Concept: https://www.gurufocus.com/news/1471569/behind-the-numbers-peter-lynch-and-fair-value

Original code: https://www.tradingview.com/script/Y5bvwFfr-Peter-Lynch-Value/

Current code (Formatted by ChatGPT):
# Calculate Earnings Per Share (EPS) using financial data
def EPS = EarningsPerShareTTM();

#PERatio = input(15, title="P/E Ratio", step=1)
def PERatio = close / EarningsPerShareTTM();
input PE = 15;

# Calculate Fair Price based on EPS and P/E Ratio
#fairprice = EPS > 0 ? PERatio * EPS : na
#plot(fairprice, color=color.green)

# Calculate Earnings Estimate for the fiscal year
#earningestimate = financial(syminfo.tickerid, "EARNINGS_ESTIMATE", "FY")

# Calculate Fair Price Estimate based on Earnings Estimate and P/E Ratio
#fairpriceestimate = earningestimate > 0 ? PERatio * earningestimate : na

# Plot fairprice and fairpriceestimate on the chart.

here is a lower study to experiment with.
it draws bubbles with some variable values

some financial functions have a value on just 1 bar out of 3 months. so you have to save the value till the next value comes along.

Hello everyone, I have little understanding of thinkscript programming. I am needing your help to debug a code that you gave me, in order to have a script that does a retrospective test of buying and selling operations, every time two Hull moving averages (10 and 20 periods respectively) cross each other and at the end sample the import in $ obtained (starting, for example, from an initial capital of $1,000).

I add the code below.-


# Get the symbol of the instrument on screen
symbol = symbol;

# Variables to store signals and data
buySignal = false;
sellSignal = false;
buyPrice = 0.0;
sellPrice = 0.0;
currentBalance = initialCapital;
totalProfit = 0.0;
totalTrades = 0;

# Calculate Hull moving averages
hullMA1 = hullMA(symbol, periodMA1);
hullMA2 = hullMA(symbol, periodMA2);

# Iterate through the defined time period
for (i = 0; i < barCount(symbol); i++) {
# Get the current data bar
bar = bar(symbol, i);

# Generate buy/sell signals
if (hullMA1 > hullMA2 and not buySignal) {
buySignal = true;
sellSignal = false;
buyPrice = bar.close;
log("Buy: " + bar.close + " - " + bar.date);
} else if (hullMA1 < hullMA2 and not sellSignal) {
buySignal = false;
sellSignal = true;
sellPrice = bar.close;
log("Sell: " + bar.close + " - " + bar.date);

# Calculate and record profit/loss
profit = sellPrice - buyPrice;
totalProfit += profit;
totalTrades++;

# Reinvest profit in the next buy
currentBalance += profit;
buyPrice = 0.0;
}
}

# Display results
plot("Hull MA1", hullMA1, color.blue);
plot("Hull MA2", hullMA2, color.orange);
plot("Close Price", bar.close, color.black);

# Display trade summary
log("Final Balance: $" + currentBalance);
log("Total Profit: $" + totalProfit);
log("Total Trades: " + totalTrades);

# Display summary message
if (totalProfit > 0) {
alert("Congratulations! You made a total profit of $" + totalProfit + " in " + totalTrades + " trades.");
} else if (totalProfit < 0) {
alert("Sorry, you had a total loss of $" + totalProfit + " in " + totalTrades + " trades.");
} else {
alert("No profit or loss was made in " + totalTrades + " trades.");
}

# Adjust parameters
def periodMA1 = 10;
def periodMA2 = 20;
def initialCapital = 1000.0;

strategy(periodMA1, periodMA2, initialCapital);
# END CODE

I greatly appreciate your contributions.-

hello and welcome.
you have found out that chatgpt is worthless when it comes to thinkscript. it confused pine functions as thinkscript, or just makes up things.

the best way to learn is read the manual and type in the examples and change them to see what happens.
https://tlc.thinkorswim.com/center/reference/thinkScript

-----------------------

here is a code that draws arrows
it compares the current high to the high several bars ago. if higher then draw an arrow

the plot formula makes a comparison, then assigns a price level for the arrow

Code:
# test_arrow
input bars_back = 10;
# compare the current high to the high several bars ago. if higher then draw an arrow
plot z = if high > high[bars_back] then low else double.nan;
z.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
z.SetDefaultColor(Color.cyan);
z.setlineweight(3);
z.hidebubble();

Hello everyone!! I am new to this and would like to request your help to
debug this script, so that it makes a profit and loss report, between two dates to be determined, in order to speed up the search for strategies. Thank you very much!!


# Initialize the capital
def capital = 10000
def initialcapital = capital
def current capital = capital
def start date=??
def finish date=??

# Initialize the number of shares
actions = 0

# Check the crossings and perform operations
if crossover(hullMA1, hullMA2)
{
# Make purchase
shares = currentcapital / close
currentcapital = 0
}

if crossunder(hullMA1, hullMA2)
{
# Make a sale
currentcapital = shares * close
actions = 0
}

# Calculate the accumulated money
accumulatedmoney = current capital + shares * close

# Show the report
AddLabel(yes, "Initial Capital: $" + InitialCapital + "\nCurrent Capital: $" + CurrentCapital + "\nAccumulatedMoney: $" + AccumulatedMoney)
