The options for this QQQ Nasdaq-100 ETF are toxic, or is it really because there are many participants that maximizes the harvesting? Compared to others, I feel the difficulty is the greatest, and it's also because my skills and judgment are not up to par. I checked the accounts today, I've never made a profit on the one-sided options for Nasdaq QQQ, all are losses. At least other major asset classes are somewhat accurate, but making money from these one-sided Nasdaq options is just too hard.
