On 18-3-20 i bought 2701 shares of jindal steel at the rate of 105.5 on mis for day trading. But at end of the day it didn't square off automatically. But these shares were kept at holdings on my account, on next day 19-3-20.in that day share value of jindal steel down further to 96.75 and it makes me loss of around 20000rs/- for me. Who would be responsible for my loss. Its zerodha, because if zerodha squared off my trading on 18-3-20, the loss would be around 7500rs/-. Please explain to me.
