By Mohammed Isah, technical strategist and head of research at FXTechstrategy.comCrude oil has staged a rally and now looks to head further higher toward the 83.31 level having reversed its last week losses. Beyond that level will open the door for a run at its 2010 high at 93.93, with a turn above there resuming its broader medium-term uptrend and allowing for further up move toward the 85.00 level. Support lies at the 78.83 level. Gold is also building on its Friday gains as it is maintaining a bid tone in today's trading session, though marginally. Risk of further higher prices exists toward the 133.18 level and then the 1,144.88 level. Pullbacks, if seen, will find support at the 1,085.03 level. Silver now has its eyes on the 17.62 level, having followed through higher on its Friday recovery today. Above the 17.62 level will clear the way for further strength toward the 18.87 level. Support lies at the 16.71 level. Wheat remains on the defensive despite is bid tone seen today. The commodity closed sharply lower the past week, breaking key supports and turning focus to the 425 level. Corn is also retaining its broader bearish tone, though seen maintaining a bid tone today. That move should eventually fade and turn the commodity back down.
