Maybe this quote from bill will help
In general, the swing high or swing low must happen at the same time, but on the chart you posted the first swing lows do not happen at the same time. The E/U low happened at 04:30, and the U/C low happened at 05:00.
DislikedJust be sure the highs and lows, that are being looked at for divergence are synchronous between the two pairs.
In other words, make sure the highs happen at the same time as well as the lows.Ignored
