earlier, it was 50 %, i.e. you could enter buy or sell order 50 % above or below last closing price.
now, different rates for different shares ! Touchwood has a higher selling band than CINV for eg.
I spoke to my broker. he agreed. direction from SEC and nobody knows the formula but he confirmed that bands are different and they do not have a chart. trial and error to enter a sell order at max price.
how absurd is this ?
