Risk Quantification - Early History of Option Pricing

The article reminds of the world of futures contracts closed between subjects in the Austrian-Hungarian economic space in the period of ca. 1986-1914; an approach to the pricing of option contracts more than 100 years ago is elucidated. The form of a phenomenon of that time that will be called call-put parity in the future is explained. The author describes the procedure of option contract pricing in the form as it was known to our ancestors; this is the reason why he does not use mathematically formalised notation that was developed later.
