F&O trading problem

I have taken short positions on 12th November in future contract expire 26 November in REC LIMITED @119.25 but at 9.34 PM in my trading account auto trade brought and sell with difference of Rs.6 due to corporate action. Is it possible or not. It has effect my profile.

As REC has announced extraordinary dividend on of >5%, On ex-date, ie. November 13, the prices of the F&O were adjusted accordingly, this does not affect your P&L. You can check out this post, more has been explained in detail there:

My broker(
icici direct )has deduced my profit of Rs.6 in my trading account

Best if you get in touch with them.
