Divergence occurs when the indicator fails to imitate the pattern on the price chart, a sign of trend weakness and likely reversal. In an up-trend, if the price makes a new High (a higher peak than the last) but the indicator fails to do so, that is a bearish divergence.
You can see the supports that can resist the price fall However, 30k is strong support breaking it will get the price to the bottom at 20k.
