perform a search on the BNBUSDT chart.P any maximum and minimum determine the maximum and minimum of the Japanese candle, which is at the extreme, and build Fibonacci levels from 0 to 1 on the extreme candle, where 0 should be at the extreme.

  # 1. Find MAX and MIN from the chart.
  chart = fetch_ohlcv(symbol, timeframe)
  chart_max = chart.iloc[-max_candles:].max()
  chart_min = chart.iloc[-min_candles:].min()
  # 2. Determine the candle of the extremum and build Fibonacci levels
  if chart_max == chart['high'].max():
    extreme_candle = chart[chart['high'] == chart_max]
    build_fibo(symbol, timeframe, extreme_candle.index[0])
  elif chart_min == chart['low'].min():
    extreme_candle = chart[chart['low'] == chart_min]
