I bought $NOK long due to 5G and a possible takeoff of the stock. I entered NOK too high at 4.49 and should have waited a day or two when it dropped to 4.23 then bought with a better entry for profit. I waited for the stock to climb back and could not wait anymore. I sold it when it was spiking at 4.5. I should have waited a day since the very next day it spiked to over 4.9. Lesson learned.
