Boeing opened a case against Bombardier at the Commerce Department's International Trade Commission in April accusing the company of dumping its C Series passenger jets into the U.S. market at "absurdly low prices." Canadian Prime Minister Justin Trudeau countered this claim by renewing his threat to scrap a potential deal to buy fighter jets from Boeing. However Boeing prices seem to be undisturbed as there does not seem to be any impact. Higher timeframe charts indicate that the prices are nearing some strong resistances around 263 levels in the next few days. The other signals flashed from the ADX and DI indicators on higher timeframe charts does indicate that the trends are getting stretched and those holding long position should start booking profits.
