Slippage on MT4 Swaps

Hi,

I was wondering if anyone can shed some light as to what kind of slippage I should be expecting on the swap rates shown on MT4. By this, I mean the difference between the rate shown, say, an hour before positions are rolled over and what you actually pay/get paid after.

I am expecting this to vary by broker. Any ballpark estimates/anecdotal evidence is welcome.

There is no slippage on swaps. What you see is what you get.

Some brokers change swaps mere minutes before rollover. This practice should be illegal but unfortunately it isn't. All you can do is keep a record of it and move on if your broker has a habit of doing it.

Thanks for the info, Kenny. I suspected this might be the case. Do you have any idea if brokers changing the rates minutes before rollover is the exception or the norm?

It tends to be the exception. Most brokers will change at least 4 to 5 hours before rollover(at the latest). Many change early in the day. But in the last hour before rollover is definitely an exception and is one of my pet peeves.

why are there spreads too high in fx platforms (mt4s and even fxcm)?

I don't see any holiday or problem

There are two most common reasons for high spreads:
Low liquidity
High Volatility
