How create scripts and trends by script ?

[Val]

I suggest using a single script attached to object tag, this way you can dynamically add/remove objects. See this doc: http://openrb.com/docs/lua.htm#grp.addtags

You can use LuaSocket http request to create new trend by sending a POST request. I'll provide an example later.

Thank you for your answer, I think I will use the POST request solution.
