I had a CSP for ASTS on Friday at 80. It went down 10%, and eventually under the 80. I bought to close it, and I ended up with a net positive (got initially around 1.2$, closed at 0.7$).
Before I just let assignments happen and then used a CC. I felt glad I was able to close and leave without assignment and all the margin. I sold another CSP for next Friday at 65.
