Selling puts on dips within uptrends, there’s nothing wrong with that since they’re “with the trend”.
Ideally, you’d want to sell puts around the bottom Bollinger Band on the daily chart and/or as close as possible to the 200-day moving average. it may or may not get that low, but those would be more ideal. It’s got a shot at that bottom band.
Glad you took in some nice income on an asset that in-and-of-itself does not put out any income.
One thing you could consider is dividing your money in half and selling some puts now after this huge intraday slam lower in SLV and if it were to hit the bottom Bollinger Band on the daily chart or the moving average, to sell (to open) your remaining puts. Just a thought. In the end, that decision has to be yours though.
