create doji recognition in csharp

A doji is a type of candlestick pattern in technical analysis that indicates indecision and potential trend reversal. It is identified by a small body with a long upper and lower shadow. Here's an example of how to create a doji recognition method in C#:

main.cs
public bool IsDoji(List<double> high, List<double> low, List<double> close)
{
    int len = high.Count;
    bool isDoji = false;

    for (int i = 0; i < len; i++)
    {
        double body = Math.Abs(close[i] - close[i - 1]);
        double shadowUp = high[i] - Math.Max(close[i - 1], close[i]);
        double shadowDown = Math.Min(close[i - 1], close[i]) - low[i];

        if (body <= shadowUp && body <= shadowDown)
        {
            isDoji = true;
            break;
        }
    }

    return isDoji;
}

This method takes in three lists of doubles that represent the high, low, and close prices of a financial instrument over a certain period of time. It loops through each data point and checks if the candlestick pattern meets the criteria for a doji (i.e. small body with long shadows). If it finds a doji, it returns true; otherwise, it returns false.

Note that this is just one way to create a doji recognition method in C#. There are many other approaches and variations of the method depending on the specific requirements and use case.
