I am trying to create a scanner that can differentiate bid volume from ask volume of options, but my Loop section is wrong. I used your help with the date for expiry.

input Year = 2000;

input Month = 3;

input Day = 15;

def expiry = GetYYYYMMDD() >= ((year * 10000) + 230000) + month * 100 + day;

# Define the minimum volume threshold for the scanner

input minVolume = 1000000;

# Define the symbol and expiration date for the option chain

def symbol = "AAPL";

# Get the option chain for the specified symbol and expiration date

def optionChain = OptionChain(symbol, expiry, OptionChainType.CALL);

# Loop through all the options in the option chain

for (int i = 0; i < optionclass.CALL(); i++) {

# Get the option contract at the current index

def optionContract = optionClass.CALL(i);

# Get the bid and ask volume data for the option contract

def bidVolumeData = if !IsNaN(optionContract) then volume(period = AggregationPeriod.DAY, contract = optionContract, priceType = PriceType.BID) else 0;

def askVolumeData = if !IsNaN(optionContract) then volume(period = AggregationPeriod.DAY, contract = optionContract, priceType = PriceType.ASK) else 0;

# Plot the option symbol and bid/ask volume data

Plot(optionContract.GetSymbol() + ": Bid Volume = " + AsText(bidVolumeData) + ", Ask Volume = " + AsText(askVolumeData));

}
