I estimate this will happen around June 10th. The weekly MACD hasn't been green since January.
Sorry, I was off by 1 day. Missed the 10th by that much...
We actually have a green closed candle on bitfinex's MACD. Bitstamp's just turned green with the start of the new week.
Being off by 1 day in BitcoinLand is still a bullseye - good on you!
