can you explain the chart please?
The price in the top chart is declining during the period from the middle of the 27th to today the 29th. Meanwhile, in the bottom graph, the Moving Average Convergence/Divergence (MACD) is rising (the green bars are going from negative to positive over the same time period).
Normally price and the MACD move together. When they diverge and move in different directions, this indicates a reversal is imminent on whatever time period you are looking at.
The divergence is suggesting that the price of a BitCoin will fall over the next few days. (Note that if the divergences were switched, the price would be expected to rise.)
Also note that this is only one indicator and is not 100% accurate. It is just one of the tools technical analysts use.
