I’m building a personal trading application using Node.js and Kite Connect. 1. Does a successful POST /margins/orders response with product: "MIS" confirm that the specified exchange and stock currently permit MIS orders, or does it only calculate the margin requirement? 2. For an MIS request, does leverage: 1 mean MIS is blocked, or simply that trading requires full margin? 3. If the margin response does not confirm eligibility, which supported source should identify MIS eligibility separately for NSE and BSE listings? 4. How should an application detect intraday changes to these restrictions without placing real orders purely to test eligibility? For example, I would check NSE:INFY and BSE:INFY independently. I understand that any pre-check cannot guarantee subsequent order acceptance. An official documentation link or example response would be helpful.
