There are lots of opinions on this. I believe that you have to come to a decision, yourself, as to which direction the Daily FT is going. Even that can be wrong.
Once that you have decided on direction----down, for example, you should endeavour to find the top for the day and enter a short position there. If you enter on opening, then you are, more or less, telling the market which way it has to go to please you. . This is not logical, although lots of traders do it because they work better knowing that their rules have been obeyed, even though they lost on the trade! You should work on the law of probabilities and if you think that the daily direction is down, you look for the tops on the intraday.
SR lines? I like the hourly chart for this.
Personal opinion
, I'm sure lots will not agree.
I mentioned the FT and I see that you are an American. Take no notice. Any index or share will do.
