#silver $SLV : take $250 profit & new entries

I continue rolling credit put spreads in silver ETF SLV. This is an income trade where interest on the invested capital is collected instead of buying a dream of the unlimited upside. The closed positions yielded 10% in 240days.
In the wake of the coming liquidity crisis, the new entries were moved far-out in time to collect more cash aka premium.
