Major discrepancy between 200 SMA calculations

Greets All

I am experiencing a significant difference between the 200 SMA calculated by Metatrader when compared to commercial 200 SMA values avaliable from fx sites.

For example EURUSD 10 April 09 200SMA calculated on Daily data; 1.3834 from MIG research, whilst Metatrader 4.0 calculates the 200 SMA to be 1.3369.

In my ignorance am i missing something obvious?

Thanks

There will be price differences between those two brokers, and since a 200 SMA makes its calculation from 200 BARS the resulting difference will be noticeable. Try and see what a 10SMA looks like...

Also check their and your time zones...
