You can use variables **$size** and **$entry** wherever you see \<size> and \<price>. You can  enter \<size> as the base / the underlying asset, in USD value (using "$") or as a percentage of the available balance (using "%"). \<price> can be specified as an absolute price or as a distance from last price (relative or in %). See [Variables](https://docs.insilicoterminal.com/documentation/overview#variables) for more details
