People say buy when price makes a new high. Examine it logically. Every time price makes a new high it has to make a recent high. Figure its previous high was 70. For it to go to 80, it has to go past 70, so getting some at 71 allows you to follow it up. But it might not go that far. People say buy when this indicator does whatever. When price creates a crazy trend that indicator will give that signal, but just because that indicator shows a signal does not mean price is going to keep going. Very important points.
