Request for Additional Candle Pattern Criteria

[Jason]

Not sure if this would be a feature request or if this achievable currently without my awareness but I would like to ask if it's possible to add a criteria to one of the candle stick patterns available in the paintbars. I wish to use the "StrongLine" pattern. Currently I can set the RangeAveragePeriod for the detection and as I understand it the pattern is matched when the candle's range becomes larger than this RangeAveragePeriod. What I would like is to be able to set a threshold for the match such that a match is not returned unless the candle range exceeds a percentage or multiple of that RangeAveragePeriod. For example, only if the candle is 2 times the length of the RangeAveragePeriod or 150% of the RangeAveragePeriod would an alert be issued. This would provide us with a huge degree of flexibility in avoiding false positives.

that is a bit specific. What I can do to solve your problem is just give you the function for StrongLine - you can then put it into your Paintbar after the MainCalculation function, and then modify it however you want:

public Boolean StrongLine(int Ago = 0, int RangeAveragePeriod = 10)
{
    Double RangeAverage = CandlePattern.AverageCandleBody(RangeAveragePeriod);

    double body = CandlePattern.CandleBody(Ago);
    if (body >= RangeAverage * 3 &&
        CandlePattern.BottomWick(Ago) <= body &&
        CandlePattern.TopWick(Ago) <= body)
    {
        return true;
    }
    return false;
}

 

You can just copy/paste the above code in its entirety at the end of your paintbar and reference "Strongline" instead of CandlePattern.Strongline in your regular script code

Great, thanks! Am I correct then to conclude from this that the function is already requiring the candle body to be at least 3 times the size of the average candle range across the period? I wouldn't have thought it to be so demanding just from seeing it at work in charts.

yes, 3 times 10 candle average, unless you specify a different amount for RangeAveragePeriod
