How to place options straddle, strangle, and spread orders in FYERS, and how much margin required for the same?

Basket order facility needs to be supported on the trading platform to place all legs of a straddle or strangle in one go. But this basket order is currently not supported on the mobile or web platform, so you will have to manually place orders for each leg on its own. The risk of placing orders for each legs separately is the slippage cost & the extra brokerage charges involved.
