Gold New All Time High Retrace Averages (Idea)

Please see chart for the details of this idea. Every time gold (XAUUSD) has hit a new All time high, it has fallen the number of pips (approximately) shown on the chart, before it resumed enough momentum to retrace about half of it's fall. This can be used to gauge how much we expect Gold to possibly fall right now, after it just reached a new All Time High of around 2483
