Hello Mahesh,
You can have only 1 file with a same name in a dircetory. 
So if u want the 1 min snapshots of the realtime data then u have to 
modify
 the aqd.format as mentioned I would request u to again reread 
the doc so your doubt would be cleared 
The idea is to keep a backup of the orginal aqd.format as aqd.eod and 
the modified one as aqd.rt so whenever u want the rt snapshot data copy 
the aqd.rt to aqd.format and when u dont wont rt data and just want the 
rt singlebar as the default u copy aqd.eod to aqd.format
BUT BUT do all this after u close all instances of ami and remember 
what u have kept then run the ami with the respective data.
Little tricky but i didnt find any better solution without paying the 
ieod data looters who do nothing but use this same trick and sell their 
utils for Rs 5000 to 60000 pa to get data from yhaoo and put it in ami.
Actually the data they get is also from yhaoo so it would be sheer 
ignorance and a folly to pay for this simple little trick. And instead 
of using amiqote they pay more than even what A new ami would cost.
And what
 more blunder then this that people dont pay for original ami 
but can buy this rt data trick for Rs 5000 to 60000 p.a.
Hope this helps.
and the money saved can be used to buy Original Ami. It is really a 
wonderfull product from TJ.
Thanks TJ for this.
