Crude oil charts are giving us a short-term buy signal today as we approach the end of the current reversal zone for crude (it ends early next week). It looks like yesterday's low at $46.68 could be the bottom of the current medium-term cycle, and if so, we could see a rally back to $55 or higher. I am therefore going to enter a long position in crude today. We can place a stop loss at yesterday's low ($46.68).
