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.

Yes, I'm finding that it can be tricky to obtain ThinkScript code with out errors from ChatGPT3.5. I haven't subscribed to ChatGPT4 to see if its better at coding. Which version are you using, MerryDay?

I am fortunate to have been given the ChatGPT Enterprise to play with.
Yes, each version that comes out builds on the previous versions.
But ThinkScript has a tiny number of users relatively. I don't think you will see explosive growth differences in any version.
It has taken a year for AI to incorporate basic TS syntax. I expect it will take 2years or more for it to assimilate TS complex coding models.
 
Microsoft CoPilot is now a part of the WIndows 11 OS. You can upload images, then ask questions about the uploaded image. Yesterday, I uploaded a TOS chart, and asked it a few questions about the probable direction of the stock as illustrated by the chart. It did a pretty good job. Give it a try. CoPilot is based on ChatGPT 4, so it is the current version. And it's free.
 
Hello guys,

I'm new to the forum and new to coding. I came up with a script that would return stocks that traded more than 1RVOL yesterday, closed at the higher/lower 25% of the day range, and are trading near yesterday's high or low. This is a trend continuation set up. I am getting delays on the results. Stocks that meet my criteria at let's say 935EST are not showing on my dynamic watchlist until after 10am. Is there something wrong with my code?

# Inputs
input rvolThreshold = 1.5;
input atrLength = 14;
input longCloseRangePercentage = 75;
input shortCloseRangePercentage = 25;
input minATR = 1;

# Calculate RVOL
def dailyVolume = volume(period = "DAY")[0];
def avgDailyVolume = Average(volume, 20);
def rvol = dailyVolume / avgDailyVolume;

# Calculate ATR and Day Range
def atr = ATR(atrLength);
def dayRange = high - low;

# Check if ATR is greater than or equal to 1
def atrCondition = atr >= minATR;
# Long Side Conditions for Day 1
def longCloseAboveOpen = close[1] > open[1];
def longRvol = rvol[1] >= rvolThreshold;
def longDayRange = dayRange[1] > atr[1];
def longCloseRange = close[1] >= high[1] - (dayRange[1] * (1 - longCloseRangePercentage / 100));
def longDay1Condition = longCloseAboveOpen and longRvol and longDayRange and longCloseRange and atrCondition[1];

# Short Side Conditions for Day 1
def shortCloseBelowOpen = close[1] < open[1];
def shortRvol = rvol[1] >= rvolThreshold;
def shortDayRange = dayRange[1] > atr[1];
def shortCloseRange = close[1] <= low[1] + (dayRange[1] * (shortCloseRangePercentage / 100));
def shortDay1Condition = shortCloseBelowOpen and shortRvol and shortDayRange and shortCloseRange and atrCondition[1];


# Get previous day's high and low
def prevDayHigh = high(period = "DAY")[1];
def prevDayLow = low(period = "DAY")[1];

# Calculate Day 2 retracement levels for both Long and Short sides
def rangeDay2Long = (prevDayHigh - prevDayLow) * 0.51 + prevDayLow;
def rangeDay2Short = (prevDayHigh - prevDayLow) * 0.49 + prevDayLow;

# Initialize the retracement condition variables for both Long and Short sides
def retracementConditionLong;
def retracementConditionShort;
if !isNaN(close[1]) {
retracementConditionLong = CompoundValue(1, if low >= rangeDay2Long then 1 else 0, 1);
retracementConditionShort = CompoundValue(1, if high <= rangeDay2Short then 1 else 0, 1);
} else {
retracementConditionLong = Double.NaN;
retracementConditionShort = Double.NaN;
}

# Long Side Conditions for Day 2
def longCondition1 = high >= prevDayHigh * 0.99;
def longConditionDay2 = longCondition1 and retracementConditionLong;

# Short Side Conditions for Day 2
def shortCondition1 = low <= prevDayLow * 1.01;
def shortConditionDay2 = shortCondition1 and retracementConditionShort;

# Combine Day 1 and Day 2 Conditions for Long and Short sides
def combinedLongCondition = longDay1Condition and longConditionDay2;

I am tyring to fix this particular line that is highlighted in red in the TOS script as an error
plot bbUpper = bb.upperband;

Here is the script:

reply to post167

should have had the .upperband on the end of the bb formula , not the variable
def bb = BollingerBands(price = close, length = length, numDevDn = -2, numDevUp = 2);

def bb = BollingerBands(price = close, length = length, numDevDn = -2, numDevUp = 2).upperband;


bb is just a variable, not a function, so can't use .upperband
plot bbUpper = bb.upperband;
if it was a function, would need ()

reply to post166

there is an error
there is a ! in the top left of chart

trying to self assign volume
def volume = volume;

why would you do this ?
delete that line and it will plot arrows

why do people use variable names of commonly used constants , functions......

ps , to make a stacked volume bar chart, look for example codes that use addchart()

Hi @halcyonguy - When you get a chance can you help me with a post I made to the ChatGPT, BARD, thread #170?
i started to look at it. i get interupted a lot.. sorry. i I think it has 2 lines that are above 0 . do you want each line centered around 0? or did you want one of them flipped to be an inverse and on the negative side??

this finds the highest and lowest value of each line. then shifts them down, to be centered around the zero line

I don't understand thinkScript yet, I just trade... but I was trying to have ChatGPT make a script for me that would allow me to get in and out of trades quicker because I often have to react right as a trendline is created with my strategy.

My strategy is pretty simple, I just combined the 9/20 cross with an ABC trendline retracement strategy that I saw online from SMB Capital;

When the 9 SMA is above the 20, I look for a very recent trendline of 3+ consecutive candles trending down, to be broken to the upside by 5-10 cents depending on my judgement about the steepness of the trendline. When the 9 is below the 20, I look for the break of an uptrend to the downside. Sometimes there's a retracement right there, sometimes I have to wait for the retracement to occur. I just wanted a thinkScript that would draw the up or downtrend lines depending on where the 9 is in relation to the 20, and be looking to update it at every candle close. So that I can focus on executing trades, and making sure any of my other rules are met (I don't enter when I perceive there to be a "bubble" e.g. prolonged trend without any recent crosses and the 9/20 are quite far from each other - unless price retraces back into the fishtail between or behind the SMAs and then breaks that retracement line).

There's also a quirk that if the first and third candle are connected (this is a must), but the second candle is "contained" e.g. it's floating and doesn't touch the TL, then it's valid. However, if the second candle breaks below an uptrend line (or above a downtrend line) - THEN I keep the angle of the trendline from candles 1 and 3, but simply "float" it up or down (slide it after drawing it) until it makes contact with the second candle's low or high point (high for 9/20 up with down retracement line, low for 9/20 down with up retracement line).

Here's the script Chat GPT wrote me, and syntax errors from TOS at the bottom:

Hello -

I have another script that I could use some help with. The indicator below is a volume histogram with an aggregation period of 3min. The bars on the histogram move 3 bars at a time. Is it possible to keep the aggregation period at 3min or more but have the bars move one bar at a time/1min etc. if on 1min chart? See image below. Thanks.

declare lower;

input useTickData = no;
input displayLabels = no;
input dataSmoothingType = {default Exponential, Simple};
input smoothingLength = 3;
input dataTimeframe = AggregationPeriod.THREE_MIN; # 3 minutes for data aggregation
input volumeTimeframe = AggregationPeriod.MIN; # 1 minute for volume

# Data processing for price
def price;
if (useTickData) {
price = close;
} else {
price = close(period = dataTimeframe);
}

# Data processing for volume (updated every 1 minute)
def volumeData;
if (useTickData) {
volumeData = volume;
} else {
volumeData = volume(period = volumeTimeframe);
}

# Applying smoothing to the data line
plot Data;
switch (dataSmoothingType) {
case Simple:
Data = Average(price, smoothingLength) - Average(Average(price, smoothingLength), smoothingLength);
case Exponential:
Data = ExpAverage(price, smoothingLength) - ExpAverage(ExpAverage(price, smoothingLength), smoothingLength);
}
Data.SetDefaultColor(Color.WHITE);
Data.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

# Defining buy and sell volume
def buyVolume = if close > close[1] then volumeData else 0;
def sellVolume = if close < close[1] then volumeData else 0;

# Resetting the volume calculation each day
def isNewDay = GetDay() != GetDay()[1];
def intradayBuyVolume = if isNewDay then buyVolume else intradayBuyVolume[1] + buyVolume;
def intradaySellVolume = if isNewDay then sellVolume else intradaySellVolume[1] + sellVolume;

# Adding a label to display the intraday volumes
AddLabel(displayLabels, "Buy Vol: " + intradayBuyVolume + " | Sell Vol: " + intradaySellVolume,
if intradayBuyVolume > intradaySellVolume then Color.GREEN else Color.RED);

Hi Folks - I posted in ChatGPT, BARD, Other AI Scripts Which Can't Be Used In ThinkOrSwim. Post #173. Can someone please help me with that? Thank you for anyone that can help!

its only been a day. be patient. no need to repost. when someone has the time and knowledge , they will look at it. there are some very talented people here.

no, i don't think it can be changed to how you asked. when using 2nd aggregation data, the data has the same value for several bars, there's no getting around that..
Maybe instead of using second aggregation. You could use an average of close, with a length of 3, and use that as your data source. Then it will be smoother...??

Thank you, may bad. I would like to maintain the stepped appearance, rather than transitioning to a smoothed representation. Additionally, I'd like to adjust how the bars move in the histogram visualization. Currently, when set to a 3-minute aggregate, three bars move together. Instead, I would prefer if each bar could move independently, updating at 1-minute intervals while maintaining the higher aggregate period.

can't do it. if using 2nd aggregation, formulas will have stepped outputs. the same data exists on several bars.

I tried making the following modifications, not the stepped pattern I was hoping for. Would it be possible to infill the missing bars by extrapolating the rate of change so that they infill at 1min or chart setting?

declare lower;

input smoothingLength = 15;
input aggregationPeriod = 2; # User-defined aggregation period

input momentumLength = 2; # Adjustable momentum length
input momentumMultiplier = 1; # Adjustable momentum multiplier

# Calculate bar index for aggregation
def barNumber = BarNumber();
def isAggregationBar = barNumber % aggregationPeriod == 0;

# Obtain current price
def price = close;

# Calculate simple or exponential smoothing for 1-minute data
def dataOneMin = ExpAverage(price, smoothingLength);

# Aggregate or summarize data based on user-defined period
def aggregatedData = if isAggregationBar then dataOneMin else aggregatedData[1];

# Calculate the momentum
def momentum = (aggregatedData - aggregatedData[momentumLength]) / aggregationPeriod;

# Initialize a variable to hold the infilled data
def infilledData;
if isAggregationBar {
infilledData = aggregatedData;
} else {
# Calculate the value for non-aggregated bars
infilledData = infilledData[1] + momentum * momentumMultiplier;
}

# Centering the plot around a zero plane
plot Data = infilledData - infilledData[1];

Hello,

I wrote the following stock screener code but found that it gives me a few results that break just about every condition in my script. I am new to ThinkScript so believe I may be doing something wrong.

Code:
#Variables
def minPrice = 1.00;     # Define minimum stock price.
def minAboveLow = 0.30;  # Define minimum % above 52 week low.
def maxBelowHigh = 0.25; # Define maximum % below 52 week high.
def ma50CloseDays = 10;  # Define number of days for stock to close above the 50 day moving average.
def minVol = 500000;     # Define the minimum 50 day average volume.

#Define stock price for screening.
def price = close;

#Define moving averages
def ma50 = SimpleMovingAvg(price, 50);   #50 day price SMA.
def ma150 = SimpleMovingAvg(price, 150); #150 day price SMA.
def ma200 = SimpleMovingAvg(price, 200); #200 day price SMA.

#Define moving average trends
def ma50Trend = SimpleMovingAvg(price, 50) [21];   #50 day price SMA from 21 bars ago.
def ma150Trend = SimpleMovingAvg(price, 150) [21]; #150 day price SMA from 21 bars ago.
def ma200Trend = SimpleMovingAvg(price, 200)[63];  #200 day price SMA from 63 bars ago.

#Define average volume
def avgVol = SimpleMovingAvg(volume, 50); #50 day volume SMA.

#Define days closing above SMA (50)
def ma50Close = Sum("data" = price > SimpleMovingAvg(close, 50), "length" = ma50CloseDays);

#Define 52 week high and low
def low52 = Lowest(price,252);   #Lowest close from teh past 252 bars.
def high52 = Highest(price,252); #Highest close from the past 252 bars.

def condition1 = price > ma50 and price > ma150 and price > ma200;
def condition2 = ma50 > ma150;                                   
def condition3 = ma150 > ma200;
def condition4 = ma200 > ma200Trend;
def condition5 = price >= (1 + minAboveLow) * low52;
def condition6 = price >= (1 - maxBelowHigh) * high52;

#Require price to be greater than $1.00 to avoid penny stocks.
def condition7 = price >= minPrice;

#Require volume SMA (50) to be greater than X to avoid thinly traded stocks.
def condition8 = avgVol >= minVol;

#Require the price to be greater than SMA (50) for the past X days to avoid volative stocks.
def condition9 = ma50Close >= ma50CloseDays;

#Require the 50 and 150 day SMAs to be trending positive for the past 21 bars.
def condition10 = ma50 > ma50Trend;
def condition11 = ma150 > ma150Trend;

#Plot results
plot scan = condition1 and condition2 and condition3 and condition4 and condition5 and condition6 and condition7 and condition8 and condition9 and condition10 and condition11;

The scan provides the following results:

1699311387495.png


The top 5 results are way below my threshold of within 25% of a 52 week high and when looking at the charts the 200 day SMA is greater than the 150 day SMA and the 150 day SMA is greater than the 50 day SMA - basically the exact opposite of what I'm looking for.

Any help is greatly appreciated!
 
I don't understand thinkScript yet, I just trade... but I was trying to have ChatGPT make a script for me that would allow me to get in and out of trades quicker because I often have to react right as a trendline is created with my strategy.

My strategy is pretty simple, I just combined the 9/20 cross with an ABC trendline retracement strategy that I saw online from SMB Capital;

When the 9 SMA is above the 20, I look for a very recent trendline of 3+ consecutive candles trending down, to be broken to the upside by 5-10 cents depending on my judgement about the steepness of the trendline. When the 9 is below the 20, I look for the break of an uptrend to the downside. Sometimes there's a retracement right there, sometimes I have to wait for the retracement to occur. I just wanted a thinkScript that would draw the up or downtrend lines depending on where the 9 is in relation to the 20, and be looking to update it at every candle close. So that I can focus on executing trades, and making sure any of my other rules are met (I don't enter when I perceive there to be a "bubble" e.g. prolonged trend without any recent crosses and the 9/20 are quite far from each other - unless price retraces back into the fishtail between or behind the SMAs and then breaks that retracement line).

There's also a quirk that if the first and third candle are connected (this is a must), but the second candle is "contained" e.g. it's floating and doesn't touch the TL, then it's valid. However, if the second candle breaks below an uptrend line (or above a downtrend line) - THEN I keep the angle of the trendline from candles 1 and 3, but simply "float" it up or down (slide it after drawing it) until it makes contact with the second candle's low or high point (high for 9/20 up with down retracement line, low for 9/20 down with up retracement line).

Here's the script Chat GPT wrote me, and syntax errors from TOS at the bottom:

reply to post172

i haven't analized all your words. i just made the study plot something.
will study your rules later.

can't do this, and use formulas within if thens
plot startTrendLine = Double.NaN;
plot endTrendLine = Double.NaN;

you just put semi colon after the variable....
plot startTrendLine;
plot endTrendLine;

but, you can't use plot with formulas with recursive variables ( read previous values of same variable)
have to change plot to def, then plot later.


i changed the structure of the if then , and added [1] to some variables on the right side of =.
can't have the same variable of both sides of =.
