title: How to increment the size of candlesticks with plotly?
body: <p>I've been working on this code to plot a candlestick chart with signals and indicators using plotly, but for some reason the candles are too small. Any help on how to increment the size of the candles (not the chart)?</p>

  fig.add_trace(go.Candlestick(
      x = df.index,
      open = df['Open'],

      low = df['Low'],
