Forex trading signals

Beginner Questions
1

I have come across a Forex Signal Service that provides free as well as paid Signal service.
In the free section they provide only one signal a day and in the paid membership area
there are 8 to 10 trading Signals everyday.

I have been following them daily and I am amazed to see very good performance .
Maybe I am not allowed to give the link to the free service here in Forex factory but I will
provide their signals daily here for the benefit of all the members of Forex factory.
Just check these trades on a demo account first.

Today’s trading signals are :
6th June GBP/USD Buy 1.2933 SL 1.2898 TP 1.2973
6th June GBP/USD Sell 1.2898 SL 1.2933 TP 1.2858

These are pending orders. Remove them if not triggered by 10:00 pm London Time

I will be posting these signals here daily.
Lets hope you all benefit.

John.

Do they say what these signals are based on, like support/resistance? Else they might be pure guesswork.
