there are thousands of those rules...many which overlap other rules and even contradict them..many times sec regulators cant agree on which rule applies when...accountants with years of experience sometimes are not sure when some rules apply and when they dont...and when they check with the sec they will get 2 different answers from 2 different regulators...
"or at such other time as the SEC shall establish, by rule, in any case in which the SEC determines that such 2-day period is not feasible."
again...i dont believe a schedualed planned sale apply to the form 4 requirement...
it has been said that after a form 144 has been filed, it is neccessary to file again if the sale didnt take place...
theres nothing filed to indicate that the sale did or did not take place...
again, in a schedualed sale, i dont think anything further needs to be filed...it was schedualed and took place unless otherwise indicated...
