macd histogram from red to green

[p3ym4n]

hi friends
can you help me for this? its not working.
i calculate MACD histogram and i want this:
when MACD histogram is below 0 (is red) ea waits for it to get above 0 (is green), then buy now

Have you tried using the MACD as an Indicator rather than a Value?

I may have the Candle IDs wrong.....*

yes but its not worked
i want to buy when macd histogram goes up from 0 , then ea open position.
i used main line x signal line

@p3ym4n the @Morpheus_0 's solution should working since in standard MACD the main line is the same of histogram
