There is no luck in an individual trade. Its just statistics. If you trade for long enough and run enough trades, eventually one of them will be really “lucky” and you’ll make far more than you hoped, and one of them will be very “unlucky” and will go very bad very quickly.
There is no luck involved in getting a range of results including these extremes.
Maybe the only involvement of luck is a lucky opportunity that got you into trading or an unlucky external event that takes you away from trading. Whether these would be good luck or bad luck won’t be immediately obvious.
