I'm sure YOU know what your doing - but I still get confused -
the EURUSD is the FOREX (spot) symbol -
the EC FX is Globex futures -
Barchart is E6 for the Euro EC FX futures
but CME is 6E for the Euro EC FX futures
Symbol E6
Name Euro FX (6E)
Exchange CME
The margin you quoted is for the futures -
the Spreadsheet is EURUSD
are you using futures or FOREX ???
