We have had out x to A leg and A to B leg form.
looking for a buy in and around the 157.052 level, looking back this was a level of support all teh way back in Nov 2013 and price rose from this level which bodes well for a potential rise and completion of the C to D leg.
Point D would bring us back in line with some more recent level of support that was broken, could act as resistance if we see a rise here.
