Upstox vs Zerodha margin for MIS

Upstox margin (if you have opted for ₹30 per trade plan called priority) for MIS is half (13k for Nifty FUT) of MIS margin(26k) offered by zerodha or any other broker. is that risky or if its not so risky can others also offer the same, without having the trader to place CO/BO FOR Lower margin?

brokers have nothing to do with retailer’s risk, they want them to trade to earn brokerage,
in BO/CO margin is lower because it has compulsorily stop-loss.
