Hi, I had short sold 2 lots is ALUMINIUM and LEAD contracts in MCX and couldnt square off before expiry. Now iam getting matured error. Iam trading in MCX. Please help, what will happen.

Hello all, can anyone guide/advice me what are all the applicable taxes by exchange for commodity and currency? E.g. We have stt, stamp duty, sebi tax etc on equities and f&o.... Can anyone please let me know the exact taxes for both segments. Thanks in advance to all. Regards...
