Just a couple of quick thoughts. The $OP 4-hour MACD has formed a bearish crossover above the zero line. Simply put, a death cross is when DIF crosses below DEA—the faster line falls below the slower one. When the market moves sharply, indicators can lag, so don't rely on them alone. I just watch to see whether trading volume confirms the move; when volume is low, I'm less convinced.

This is just my personal opinion, not investment advice.
