Forex hour-scale zero-lag intermarket correlation heatmap for May 2016Fig.2.The zero-lag correlation heatmap is a 2D arrangement of Pearson correlation coefficients such that any bin in thei-th row and j-th column contains the correlation coefficient between time series i and time series j, with numbersassigned in the following order: 1 -- AUDJPY, 2 -- AUDUSD, 3 -- CHFJPY, 4 -- EURAUD, 5 -- EURCHF, 6 -- EURGBP, 7 -- EURJPY, 8 -- EURUSD, 9 -- GBPCHF, 10 -- GBPJPY, 11 -- GBPUSD, 12 -- USDCAD, 13 -- USDCHF, 14 -- USDJPY.The informative part of the picture is intermarket correlations,found away from the main diagonal in the plot.The coefficients on the main diagonal all equal 1 by construction, since they represent zero-lag correlation of the time series with itself,normalized to be 1. Forex hour-scale unit-lag intermarket predictability heatmap for May 2016 Fig.3.The unit-lag correlation heatmap is a 2D arrangement of Pearson correlation coefficients such that any bin in thei-th row and j-th column contains the correlation coefficient between time series i and time series j, with numbersassigned in the following order: 1 -- AUDJPY, 2 -- AUDUSD, 3 -- CHFJPY, 4 -- EURAUD, 5 -- EURCHF, 6 -- EURGBP, 7 -- EURJPY, 8 -- EURUSD, 9 -- GBPCHF, 10 -- GBPJPY, 11 -- GBPUSD, 12 -- USDCAD, 13 -- USDCHF, 14 -- USDJPY.
