So I've built me a cost of carry calculator and so far so good. Looking back, turning points are pretty text book at the 65-70%+ cost of carry for corn, wheat, soy beans. Not Bean Oil though! Does anyone have any experience of Bean Oil - it would seem that Bean Oil sometimes goes past full cost of carry, which 'in theory' shouldn't happen as 'the market abhors a risk free profit as much as nature abhors a vacuum' as C Smith wrote! The only possible error I can see is my quote values. If bean oil is quoted as 57.49, that means $0.5749 right (if corn is quoted as 760-6 that means $7.6075)? However if I use 0.5749 format, the spreads get nowhere near full carry ever. If I use the 57.49, thats when they go over full carry at the spread lows. it would seem im trying to fit the quotes to generate trades - a bad move, but id appreciate if anyone could clarify from their experience..... cheers....
