BITSTAMP:BTCUSD Bitcoin / Dollar
Great find. I'm thinking this is bullish because each of the times the price drops or rises hard onto this moving average we get a big rebound up or down. I've marked it on a copy of your chart in blue, (https://www.tradingview.com/x/pOvMkRma/) where in 2 instances the price just kind of launches through the MA line & picked up some major energy on the opposite side of it. It looks to me like price might be on track to pull this movement again.
