I don't even have a reason given yet.
It was a SWIFT wire if that helps.

Under what circumstances one can be reversed and in what time frame after making it?

I was using localbitcoins to sell some coins. I got the money in my bank account and released the coins to the buyer.
Several days later my bank got request for wire reversal....
So, in which cases is that possible and what one can try to do to prevent it in future.
Does it work from all countries and all wire systems? (SWIFT, SEPA...) ?

If someone can move the thread to the general forum that would be great. I registered just for this thread and really can't wait the newbie jail time since it's quite urgent for me.
