Could someone explain this to me!??

Ok, here is the deal.........

I open a 4way hedge(4pairs buy and sell each at 0.1 lot).
This is executed in about 2 seconds by EA and the total
spread for that 8pair execution is -20$ .(this is demo account, but this should not make any difference)

The thing im not clear is that this hedge oscilate around -20 to -50 bucks!
I dont get it.....if im hedged on all pairs, and there is no big difference betwen hedges(fast execution on slow market), and the total spread is
-20$....how can this thing oscilate to even -50$.
And no, there is no swap adds....this is happening through the first day of hedge execution!

Thanks for explanation.

spread increase.

Lats say i open this hedge when the spread is big for all pairs.....
let say around news time.......and let say the open spread is -50$.....
Will my hedge go back to -20$ when the spread returns to normal!??

Thanks

In your example, presuming the price stays essentially the same and the only thing changing is the spread, then you'll see fluctuations in your P&L either way based on how wide or narrow the spread is. So it would go back to "normal" only if the spreads normalize.

This is really just elementary cost of doing business (spread). I presume your strategy is based on getting some kind of price movement rather than trying to exploit the spread. If it's the latter, don't waste your time would be my suggestion...
