Traded AMD call options

Friday was a terrific trading day. Sold AMD call options $AMD 240816 190.00C$ at 7.20 at the start of trading day, bought back at 5.40 before I slept and placed them on sale at 6.60. Woke up and discovered profit of 1k plus. Nasdaq's volatility offers a great way to either make or lose money within a single trading day, unlike boring SGX.
