I've had a wierd thing happen a few times and I'm hoping someone can explain it.
I use a 100 tick chart and I have an entry filter that uses a crossing of an EMA over the centre line of a Bolinger band. Basically a EMA cross really.
Now last night is a prime example. In real time at approximately 0911hrs the EMA crossed from above the bollinger band channel to below the midline of that channel. It then crossed back above the midline at approximately 0914hrs.
I closed down the charts to go to bed about 10 minutes later. Now when I opened the charts this morning(I'm in Australia by the way) everything looked the same.
Then I logged onto my Mirus account with the Zenfire feed and updated all the data to the present time. After doing so I went back over the charts and found the EMA appears to never have gotten closer than about 1 point to the bollinger band channel.
This problem has occurred quite a few times but never with such a huge difference.
Is it a problem with my feed or the charting or is it something I'm not understanding about the way the EMA and bollinger bands are calculated?
Any help greatly appreciated.
Cheers,

P.S: I've attached a picture of how it looked after I had updated the data but I didn't think to take a picture at the time in "real time"
