Death Cross is a technical analysis pattern that arises when a short term indicator downwards crosses a longer term indicator.

A death cross in the context of decentralized finance (DeFi) refers to a bearish technical analysis pattern that occurs when the 50-day moving average (MA) of a cryptocurrency or token falls below its 200-day MA.

This is considered a bearish signal and suggests that a prolonged period of downward price movement may be ahead. This is similar to traditional finance where death cross refers to a bearish signal when short term moving average cross below long term moving average.
