Since I'm short the DMark and had noticed a possible NRID for continuation
signal, I did some digging. The difference between the lows is on globex -
the 5493 was the globex low and 5499 was RTH. Personally, I prefer including
the globex data on the currencies. Today's RTH high was 1 tick above
yesterday's while globex shows an inside day. As it stands, tonight's low is
already one tick below yesterday's globex, however it will take a break 1
tick below 5487 to confirm the continuation. The monthly chart is nasty
bearish and I've got initial target on monthly in 5350 area.
