Apologies if this comes up a lot (as I'm sure it does) but when / how often do you feel is best to buy the dip?

I know its not an exact science but I've heard a few different preferences on this such as:

- When the price decreases x% on the weekly/monthly candle
- When the price moves below the weekly/monthly negative average
- Only a couple of times a year after a major correction
- Just look at the chart and go on your experience / gut
