hi today when I started amibroker it said default database not found then I directed it to now2ami database. now it showing only 2 ticker banknifty, sbin and 3rd ticker nifty was missing. I checked now2ami database in "n" folder , NIFTY file (1850 kb) was there . then I have backfilled using nest plus. but the problem is in my database nifty was from may series so all past data gone.now the new NIFTY file in ami is 221 kb.
I have copied that 1850 KB nifty database file from ami in desktop , is it corrupted now , cause ami saying 0 bar/ no bar , when I am using this file ?
