creating a custom automated trading strategy without knowing how to code will be hard at least. you need to get yourself a programmer that can work on it. the bitshares-core api is rich enough to create any trading strategy. you basically pull the feed/order book of a market, analyze, make trade decisions client side and send orders to the dex.
i will recommend to make trading bots in python as you already have some open source code to look at in the links you provided but can actually be any lang that can read/write data to a websocket.
i can, and the community will also help in this for sure but you need to get a developer, you need to make him understand your strategy and he will get all the technical help we can provide from our side.
