To convert results to hash use to_dh method like:

all_stock_markets.to_dh
{"bitstamp"=>{"btc_usd"=>{:ask=>913.44, :bid=>912.84, :currency=>"USD", :last=>913.44, :timestamp=>1389049226.0}}, "btce"=>{"btc_usd"=>{:ask=>916.089, :bid=>914.449, :currency=>"USD", :last=>916.089, :timestamp=>1389049239.0}, "btc_eur"=>{:ask=>695.89199, :bid=>692.02567, :currency=>"EUR", :last=>692.03, :timestamp=>1389049241.0}}, "btcturk"=>{"btc_try"=>{:ask=>1909.94, :bid=>1880.0, :currency=>"TRY", :last=>1895.99, :timestamp=>1389049245.0}}, "mtgox"=>{"btc_usd"=>{:ask=>1010.0, :bid=>1005.005, :currency=>"USD", :last=>1005.0, :timestamp=>1389049229.681736}, "btc_eur"=>{:ask=>735.0, :bid=>727.0, :currency=>"EUR", :last=>727.0, :timestamp=>1389049241.310519}}}
