I can't see a "when a pending becomes a trade" block. Is it the position created block?

Hello, I am trying to get a sell pending order to trigger (as in become active as an order) once a previous sell pending order is triggered. So if the price is moving up from 0.8 to 1.0 and the first sell pending order is triggered at 1.0 I want that triggering to then activate a sell pending order below it at 0.8. Thank you very much if you can help.
