Anybody: EA Ask/Bid difference is not actual broker spread

 
Hello,

I have a demo account with Interbank FX.

When I manually execute trades on EURUSD, the spread is 2 pips.

When I run a script to display Bid and Ask in a MessageBox(), the difference is 9 pips.

When I choose "Symbol Properties" in the tester, it says the spread is 9 pips.

Why?

Is this a bug, or does the broker have a different spread for manual trading and automated trading in expert advisors?

I saw posts about changing spreads by hacking a file, but I want to know why this is happening and what I should or should not do about it.

Please help. Thank you.
 
It appears that the broker increases the spread when the market is closed and sets it back when it reopens?

The spread in the market watch window on EURUSD was 9 pips and as soon as ticks started coming in, it went back to 2 pips.

Anyone with additional information about this or links to other topics that talk about this, I would be interested.

Thanks!
