[ ABOUT ]

Identifies coins where EMA 20 crossed below EMA 50 within the specified lookback window — the death cross, widely regarded as a bearish trend signal. Uses the same looping structure as `scan_golden_cross` for consistency, checking each bar in the lookback window for the moment the fast EMA dips beneath the slow EMA.

Death crosses in high-cap crypto assets (BTC, ETH) have historically preceded significant drawdowns. For lower-cap altcoins, the signal is more volatile. Consider using `scan_death_cross` to build a short watchlist and then applying `calculate_rsi` on each result — coins in a death cross with RSI already below 40 have limited additional downside from the EMA signal alone.

[ USAGE EXAMPLE ]

example.py

bearish = scan_death_cross(coin_list, lookback=5)
for coin in bearish:
    print(f"{coin}: death cross — reduce exposure")
