Guide binary option signals review broadford

Do you mean that take the signal from the 1-5mins and use expire time of 15 mins or use the signal of 15-60 mins and take the expire time in 15 mins. I am doing research on what ways I can make money. This is just one option. Or must we wait for a signal that is 90 and 2 atleast two is green on pro strategies to make a trade.

I want to try it, would you please give me a strategy how to use it for best results.
