See the chart of crude 1 hour , here am considering two tools, fib levels and gann levels. two extreme points i have taken that is 48.06 as low and 54.09 as high u can check them after hiting the high 54.09 price retraced back to below 64.8 levels and then started reversing, then i applied gann levels to find possible resistance levels gann levels had given strong resistance at diffrent angle see the chart.......now i think 50.36 will be key support and 52.45 is resistance for upside movemnt.... now 50.75 price is in gann angle , if the price gose below 50.36 then possible chance to reach next angle
