Exposure Margin coming as 0

I am using the API to calculate margins for Equity Options. I have tried using any basket, it gives me the correct SPAN but the exposure margin is always 0. See the trade below. I am buying 1 lot of TataSteel at strike price of 1000 and selling 3 lots at strike price of 1100. It is showing me correct span but exposure margin is showing as 0.

    @rakeshr Sir,

    In the morning,the exposure was actually showing 0 for the basket shown by @shbhnkr .

    Also,the exposure was showing 0 for just the call short position(Tatasteel 1100CE).

    I had made a test basket on Kite too consisting of index options ,on Friday to check something. On Friday,the required margin was around 30k,but today morning when market opened, around 9:30,the required margin dropped to below 10k(that was below the max loss of 12k of that basket),I guess that was also due to the exposure margin being 0 at that point of time .

    Why did the exposure drop to 0 in the morning??

    There was some issue in the morning yesterday and it was fixed later.
    @sujith Sir,

    Thank you for the clarification. :)
