Rocket J Squirrel said: To address your other post, if you open a position with Short Sale, you should close it with Cover Short.
Nick0131 said: Thanks Rocket. While symmetry is nice, why not do it right. For assignments, expirations it makes no sense to me to have these type of rules: when you buy, you sell (to close). So, when you sell, you buy (to close)? No, you cover the short.
