Can we carry forward long term and short term loss for 8 years?

Can we carry forward long-term and short-term losses for 8 years if we file the ITR before on ITR? I am taking about investments and not intraday

Yes you can, provided you file your returns on time.

I was told that if I delay filing of the returns beyond the fixed date, I loose out on this option. So it is important to file subsequent returns well on time.

Disc: The above applies to investments, but not too sure about intraday etc. I am sure experts will respond on this aspect.
