Overnight has shown some early weakness in copper, which had led the general market up in a fast spurt over the past four trading sessions. This weakness can be seen in the chart below as copper nears 3.2300 and a support line at 3.2125. It has also broken a trend line, that admittedly was almost vertical. We could expect some follow through in the ES eMini SP500 contract, as it usually follows the trail copper has blazed for it.
Some support and resistance lines are drawn in blue for both instruments.
