Hello,
1) For test mode you can set your delay within the program settings.
2) Not yet. First of all MF uses a lot of information not presented in the Stream API. So we still need do "refreshes". Second, the nature of triggering in MF has the market refresh moment as the root of everything. With the Stream API there is no actual refresh but an update of some market information. So it requires rethinking of global triggering procedure. We are not ready yet to rewrite everything, sorry.
