We only want to have a start and Finish period for the EA to start a trade sequence. Inside this period it can open new sequences - outside the period it cannot. At any stage if a sequence is running then the EA can continue to add positions as normal whether in the Asian time period or not. (So if it starts a sequence right at the end of your time period window, it might still run through the Asian session.) Caillous additional option was to have it close out any trade sequence at the begining of the Asian session if you happen to have one still open by then.
