How do you enter a trade?

This is a thread for people to share their thoughts on how (what rules, indicators, targets, stops etc) they use in deciding on entering a trade.
I am posting this as someone ask me the question and I found it wasn't that easy to answer.
Naturally if you have worked long and hard on something proprietary the thread isn't about that - giving away your edge.
If you want to share thoughts on your rules and criteria for a setup - or what they should be - by all means let 'r rip!
Thought my focus is day-trading I haven't posted this in the traders lounge as it is more a chronological flow each day a new thread.
