if you have small account, yes, install news filter, but if your account is big, no, do not install news filter.
Why do i say this?
If news event causes a waterfall, and you have some trades open, it may cause huge floating losses. This is very bad for a SMALL account. But if you have a BIG account, afg will open more trades and that will create more profit. But the floating losses can blow up your account if you have a SMALL account. That is why i said...
if you have SMALL account, yes, install news filter, but if your account is BIG, no, do not install news filter.
