Do you have any information? As much as possible not speculation but arguments based on facts. I think that might be useful to all traders if we can synthesize the knowledge and experiences of community MQL5.
Advantages of floating seems be : a lower value on average, but widening on events which may trigger our stoploss.

I think - many (may be - most of) brokers are using floating spread which is increased or decreased especially during the forex news events.
Anyway - thanks for the links to spead indicators - I think - they are very usefull.
Fixed spreads brokers are better But you can use floating spread broker as well with wisdom.
I'm using floating spreads broker and i have coded it in my EA not to open order if spreads is more than 0.5 pip(s)
It's very annoying that we can edit first post after first comment. Anyway...
Another resource very useful : Forex broker spread comparison
That is one of the reason why i take this measure to prevent it. So that my EA will not open trade when there is widen spreads.
Even most of the broker who are using fixed spreads are charging 2-3pips. And this is too much for me. So, i prefer, floating spreads with my system, but not suitable for scalping.
My broker only deduct spreads when opening trade not when closing it. So when spread become widen when closing a trade, it doesn't affect me.
Most broker charge from 2-3 pips fixed spread on EurUsd. there are little brokers who charge less than that.
Floating is not suitable for scalping because the spreads may become widen when you want to open order and it may remain widen till signal expire. (Example.: you want to enter into market and take 10pips and get out but spreads become widen to the extent that you have more spreads pip to cover than pip to gain.)
