 * Why can't you understand that the info provided is definitely incorrect and outdated. Actually the formula has been used in top journals. I can provide references to articles published in top journals. Why are protecting wrong and misleading info. This is not a vandalism, it correcting a blatant error. Your job is to correct wrong info, not protect it. Otherwise, it is very embarrassing to Wikipedia and it will lose credibility. I doing Wiki a favor. Mmha1000 (talk) 23:49, 2 November 2022 (UTC)
 * No, you've been repeatedly vandalizing the article from multiple accounts. The citation your earlier accounts were attempting to add is not what it was claimed to be - an upper bound is not an exact value, and assuming a constant volatility is a different (much easier) problem than the one the article is discussing.

 * No, there is a formula (not only upper bound) and the page states that "In general, no corresponding formula exist for American options" which clearly not true, since the Black-Scholes model assumes constant volatility.
 * More imoprtantly, the recent literature that provided Black-Scholes-like formulas should be added for the record; it is more important than approximations using costly computational methods Mmha1000 (talk) 00:39, 3 November 2022 (UTC)
 * You are incorrect, and you are in violation of several Wikipedia policies, in particular WP:SOCK. MrOllie (talk) 00:55, 3 November 2022 (UTC)
 * you shouldn't make a claim without a rigorous proof. You are talking to the leading author in the topic. I'm using one account not multiple accounts. Mmha1000 (talk) 01:22, 3 November 2022 (UTC)
 * You are talking to the leading author in the topic. What do you mean by that? If you're not using multiple accounts, why are three different brand new accounts making the same edits? MrOllie (talk) 01:27, 3 November 2022 (UTC)
