RC, BSD,
After some hesitation I got my direct connection to the OCE (Odessa Commodities Exchange).
Two things struck me immediately – Odessa’s derivative prices are 5 seconds behind Rotterdam’s spot prices; they use the wrong model to price their options.
The time lag meant I was in and out almost 300 times today with an 91% win rate on the chaff future.
Regarding their pricing model, I think they’re using a modified version of Roll, Geske, Whaley rather than Vasicek’s trinomial. To cut it short, today they were quoting 0.82 delta puts at 75% iv on Apr chaff – it lasted about 10 seconds but I managed to sell 20,000 contracts of the mothers. It then suddenly plunged to 12%. And I closed at a fat profit. How much? Put it this way, my hesitation re the connection was the annual cost of £50,000. Now I don’t need to worry about this for another four years.
Grant.
