MACD Histogram Multi-Timeframe

The MACD-Histogram represents the difference between the MACD (i.e., the between the two EMAs) and the signal line (i.e., the 9-day EMA of the MACD). The histogram is positive (i.e., above the zero line) when the MACD is above the signal line and negative when the MACD is below the signal line.

HOW IS IT USED ?
A bullish crossover occurs when the MACD histogram is negative and a bearish cross over occurs when the MACD histogram is negative.

I added the possibility to add on the chart a 2nd timeframe for confirmation.
