both getbhavcopy and volume digger data have errors, the technicalities of error are as follows..........
Getbhavcopy and Volume Digger both::::
1. It does not download data for the days where exchange is open on Saturdays (eg. 8th Sep-2012) and other holidays although bhavcopy is available at NSE site.
2. It adjusts for futures data (near, next,far or I,II,III) wrongly. eg. it assumes that all the tickers repeats three (3) times, so that it starts numbering all the respective lines as 1,2,3 in a loop which is wrong because sometimes NSE bhavcopy contains tickers which are only repeated two (2) times or less. In other words, NSE FO bhavcopy contains only tickers traded woth atleas one (1) contracts, zero trades meas no data for that stock or future in bhavcopy.
i request makers of these utilities to update these errors asap.
