People write books on that subject. Hopefully this post will not end up as long as one. Two of the things that I look at are volume and fundamentals. With regard to fundementals. Lets say that you are trading the ES. Later in the day the FOMC is scheduled to announce a rate decision. Due to low liguity I would assume all breakouts to be false based on fundamentals until after the announcement.
Then I look to tick volume. Low volume moves often fail. If I like the breakout I drop to a lower timeframe and watch price action for micro support levels and a reversal formation before entering. Keep in mind that a failed breakout often means a reversion to the mean trading range and a profit opportunity in and of itself.
