search the BNBUSDT chart for any maximum and minimum to determine the maximum and minimum of a Japanese candle that is in the extreme, and plot Fibonacci levels from 0 to 1 on the extreme candle, where 0 should be at the extreme.

    # chart: chart object
    # candle: number of the candle to draw fibo from
    # num_lines: number of lines to draw

    # set baseline and extreme
    baseline = getattr(chart.iloc[candle], param)

    # find the next candle with a higher high
