i`m brand new.... in poker lanquage i`m a fish

i want to make something simple - i lay and when this lay is completly (!) matched then the bot should automatically and immediatly back the matched lay a bit higher - for instance:
lay 1.80 with 100 $
it got matched completly (not only 50$ or so it should be the complete 100$)
the bot make immediatly a back bet with 100$ and 1.90 for instance, and wait to get matched...
i guess this is a simple automation... i watched some of the youtube videos - i can lay automatically on selected markets, i can go inplay and so on, but no automatically immediatly back if the lay is matched....
somebody can help?
thanks!!!!
