there will be a lot size given, investor has to apply minimum of 1 lot or in multiples of the same.





lot size is calculated in such way


suppose for ABC company the price band is 200 to 250 rs.


so in 1 lac shares you can get maximum of 400 shares (considering the maximum price of 250 i.e. higher band).





now the lot will be in any multiples, such that application will not exceed 1 lac rs.
