Finding candlesticks

[Explore60]

Hello all,

Trying to write a script with the following conditions:

1. Find a Green bar.
2. Find a Topping Tail Red bar with a higher high and higher low in any 15 bars after condition 1 is met.
3. If both conditions are met, then draw a red arrow on any 20 bars after the 2nd condition is met that makes a lower low (trades below the low of the Topping Tail Red bar).

Is it possible to write a working script for the conditions mentioned above?

I tried Chatgpt but getting errors (please see code).

Any help with this is appreciated.

Thank you in advance.

# Define Green Candle Conditions
def isGreenBar = close > open;

# Define Topping Tail Red Candle Conditions
def isToppingTailRed = close < open
                    and high - open > close - low;
                    
# Initialize variables to track Green and Topping Tail Red Candles
def greenBar = 0;
def toppingTailBar = 0;

# Find Green Bar
if isGreenBar {
    greenBar = 1 else;
}

# Find Topping Tail Red Bar with Higher High and Higher Low within the next 15 bars
for i = 1 to 15 {
    if isToppingTailRed
       and high > high[i]
       and low < low[i] {
        toppingTailBar = i;
        break;
    }
}

# Initialize variables to track the lower low condition
def lowerLowBar = -1;

# Find a bar with a lower low within the next 20 bars after the Topping Tail Red Bar
if toppingTailBar > 0 {
    for j = 1 to 20 {
        if low < low[toppingTailBar] {
            lowerLowBar = j;
            break;
        }
    }
}

# Draw a Red Arrow with "Sell" When the Lower Low Condition Is Met
def sellCondition = greenBar > 0 and toppingTailBar > 0 and lowerLowBar > 0;
plot sellSignal = if sellCondition then low else double.nan;
sellSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
sellSignal.SetDefaultColor(Color.RED);
AddLabel(yes, "Sell", Color.RED);
