Funding IRAs through selling covered calls

I left a job last year and rolled over both my Traditional & Roth IRAs. I’ve since bought Amazon, Apple, Tesla, Visa, Norvo Nordisk (NVO) stocks (among others) and have been able to write covered calls averaging about $300 a week in premium.

I look for CCs with at least one standard deviation from the current price or 85% likelihood of profit with a ~.2 Delta. I then buy 1-3 stock shares per week with the premium.

I’ve had a couple of CCs redeemed and I usually just re-buy the same stock and sell new CCs.

Is this a viable strategy long term?
