# Long/Short signal

Once a long or a short signal is triggered by your general strategy, you can enter a position on the long or the short side, if this matches with your[ Entry in position rules Box](/triggers-boxes/entry-in-position-rules.md) parameters. 

They can also be used to exit a position if needed, with the [Exit position rules Box](/triggers-boxes/exit-position-rules.md). Without any long or short signal, you can not open a position.

It is only possible to create a long or shot signal from the [Indicators Box](/strategy-boxes/indicators-box.md), and by using [indicators](/indicators/basic-triggers.md).
