Concentration of Credit Risk [Text Block] | Note 15 - Concentration of Credit Risk: Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. As of October 31, 2024 and October 31, 2023, the Company had $739,000 and $2,237,000, respectively, in excess of the FDIC insured limit. Management has concluded the excess does not represent a material risk, based on the creditworthiness of the counter parties. The Company maintains a deposit account of $305,000 at Flagstar Bank as security for a letter of credit in a similar amount (See Note 13).
