I would Take a long position because of the next arguments (Obviously is necessary to take into account the lower time frames):
>Shortening of the down thrust. >Close to a support zone. >Incapability to look for the oversold line (Lower Red Line). >The retracements are more than the 50% showing Strength >The down movement of the 31/07 was almost reversed by the next day (Little red square), Giving signals of strength
