Hi Xbot!!, you'r right, but you can learn some very useful things.
for example, 2 years ago I bought a similar book (crude oil physical trading) and I learn that when the baltic index drops substantially, The Brent benchmark tend to trade at a wider premium to WTI. (80% of the time). Thanks to that a made my best spread ever.
I learn that the some of the big oil producers including Russia and Nigeria use Brent as a benchmark for pricing the crude they produce. In total, it's estimated that a little more than 20 million barrels of daily oil production are priced using Brent as a benchmark. So when i saw the dry baltic index going south I knew that the demand for brent (mainly due storage) will explode. I almost made 6 figures in 17 days with that spread (long brent/ short WTI)
the energy market is extremely complex and fascinating, and if somebody really want a shot, One should understand the physical and OTC side of the market very well (at least).
Im learning about the NatGas market and i found out that is even more complex.
regards and happy trading pal.
