ias='USD.CHF-IDEALPRO-CASH'")
=> [#<Trade:0x4828a80 @attributes={"tradestatus"=>"O",
"tradestrategy"=>nil, "sy
mbol_alias"=>"USD.CHF-IDEALPRO-CASH", "tradeinterval"=>"5MINUTE",
"getpictures"=
>nil, "tradename"=>nil, "id"=>"9", "grossrevenue"=>nil, "tradecomments"=>nil, "t
radedirection"=>"Long"}>]

t is an Array (see this by typing t.class)
So, t.id is going to return a value related to the Array class as opposed t=
o
the contents.

t[0].id t[1].id etc would return what you are expecting
