I think it comes to your back testing of Swings, if the 3 trades were within one swing, and going back like 300 previous swings it shows that after so many trades you encounter losing trades, then you can have a rule to stop you from taking more trend trades. That's what I do, I can only take so many trend trades within a swing, I can have other ways to get in on same bar or area and all count as one but once price leaves that area, then any other signals count as next within the same swing.
As far as skipping trades, it has never back tested to skip trades to be favorable. Really all comes down to your stats, dividing up segments of your trading day like morning, lunch and afternoon, in ES for example, each session trades a little different cause volume changes "normally", so you can expect more chop during lunch and afternoon session can be harder to trade than morning even with more volume than lunch, afternoon is more of how to really screw the uneducated than making and so called thrust in one direction. Knowing what an "average" break of a pivot helps, as the break becomes smaller, then you can expect reversal.
