Dunno the answer here guys.... I did change one chart to 2 min/50 ema to maintain the correct ema profile..... I cant say I recall changing it back so maybe that's it. The other way discrepancies can come in is the start and end time of charts. I know there are differences in Lycos for example.... Sierra rolls back the EMA as if it were contiguous with yesterday's data. Lycos starts with fresh data at the open ( I think)...
PS I've just checked my charts at work and you're correct! Last night's DOW has the EMA still set at 50. Just goes to show that it's not really that important what the setting is ie previous reference to do I use the EMA on the closing prices. Others swear by SMA. At the end of the day, find something that you understand fully, stick to it, and learn the characteristics of it'd behaviour. The same argument applies to RSI and CCI settings, and any other indicators you may use. These things are not cast in stone.
For reference, here is the correct EMA on the DOW....
