Mr Don.
could you explain step by step how to use that script?
i`ve done first two steps, i changed industry and sector files in
amibroker directory by hemscott files from
http://finance.groups.yahoo.com/group/amibroker, i checked symbol
>categories - industries.there was everything linked to right
sectors.but now i have no idea how to do everything in step 3? i mean
where that script file goes and how to use it?
(PopulateIndustriesAndTickers_v3_0.js or Industries.js , btw first
script has data stored in lines with following format
** <ticker>,<market number>,<full name>,<industry number>, second one
<ticker>,<full name>,<industry number>,i`ve got industry_data.txt
file from http://finance.groups.yahoo.com/group/amibroker whitch has
no market numbers.where to put file industry_data.txt. how to use it?
thank you

broker.sectors and

number, and a

will see

them to
