I get the following error and it is so odd

irb(main):002:0> a=TorontoTraderLoader.new('ww')

It does not make any sense. i have a overloaded constructor. i am not

No, you redefined it. No overloading in Ruby (because "Duck Typing")
sure why it does not call teh overloaded constructor


Maybe

def initialize(backTesting = nil)
@exchanges=@industries=@sectors=@stocksymbols=''
if backTesting.nil?
@dbcon=DbAccess.new(@backTestDb)
else
loaddbConn
end
loadLookup
end

is more the kind of think you want, but in the first method you
don't seem to use the param backTesting anyway.
