When volumes are low, option order does not executed, but when i reduce the sell price going at 1. 20 to 1 rs it got executed immediately even volumes are very low, why?

How is this a question?

If a buyer is available at Re.1 and not at Rs.1.20, your order will not go through unless you reduce your offer price.

Please ask some intelligent questions !

One rupee could have been a better choice than 1.2. So you got some buyers willing to buy at 1 rupee. So what’s your point?
