WHEN YOU START SHOUTING YOU SHOULD USE ALL CAPITALS OTHERWISE NOBODY WILL HEAR YOU. TO GET SOME EXTRA ATTENTION YOU SHOULD MAKE THE FONT BOLD RED. IT'S A SAD THING THIS FORUM DOESN'T HAVE BLINK.

but to answer your question anyway... metatrader uses the last known spread for backtesting. So MBT's last spread on weekend close was 18pips for this pair.
