October RBOB prices slipped in early morning action and made their way down to the 50-day moving average. Part of the initial weakness came from a soft outside market tone, as well as more anxiety ahead of this morning's US jobs data. Meanwhile, some traders indicated that October RBOB has shown a level of strength in recent sessions as it moved up towards the August high close ($2.9195). Some of that strength might have come from dislocations in US cash markets, especially in California, where near term supplies are expected to fall short of demand in September.
