To the poster asking adout Hoarizon product decayGood example is the HOD. Last time oil was this low(in USD) it peaked around $36. Today it made it to $32 high. The difference in the oil price then and now 52 week low oil $27.56 and today low oil $27.96 as of right now. Of course there is also the currency difference etc. The .40 cents difference does not account for the $4 difference in the HOD high.
