why don't you guys stop guessing and pick up a phone and call your broker or go to any broker chat and ask them, here's what i got from one broker chat, also my broker told me the smae thing by phone, this is only a hedging issue and thats it, see below.
Client Services 40: Hello this is Ben J. How can I help?
new: hi, i understand the NFA rule on no hedging, but how will the FIFO rule effect me the trader
Client Services 40: as you start to close trades, on the same currency pair, they will close first in first out
new: how does that work if im using stop loss or take profit
Client Services 40: Why don't you tell me what you think fifo is
Client Services 40: then we can go from there
new: don't realy know, can you explain, there been rumors all over the place
new: one of them being we can't put s/l or t/p on our positions
Client Services 40: Really its nothing that you need to worry about at this time because as of right now, and this could change, the platform will not be doing FIFO trades
new: but what will happen if the FIFO rule apply?
Client Services 40: It's not a fifo rule. It's a policy that some brokerages may have to take
Client Services 40: the rule is no-hedging
new: can you please explain to me how does FIFO works
Client Services 40: do you have a minute, this could take a while
Client Services 40: ?
new: yes i do
Client Services 40: Well when the new rule comes out people won't be able to have buys and sells on the same currency at the same time, so we were thinking that the platform would become OCO (One-Cancels-Other) so for example if you had a 1 lot buy open already and you opened a 1 lot sell the it would close the one buy that you had and that would be a way of closing your trade. A FIFO (First-In-First-Out) would be if, for example, you had a 1 lot buy open and then it went positive in your direction so you opened another 1 lot buy and then later opened another 1 lot buy. Then you opened a 1 lot sell it would close that first trade that you opened first
Client Services 40: But at this time if you had a buy open the platform wouldn't let you open a sell so at this time the platform is not FIFO or OCO so you really wouldn't have to worry about it
new: this is why i love you guys,thank you very much for your time
Client Services 40: Did I answer all your questions today?
new: good job explaining this to me, and yes you answer all my questions
