[Python] Json List to Pandas Dataframe

I've a json list and I can't convert to Pandas dataframe (various rows and 19 columns)

Link to response : https://www.byma.com.ar/wp-admin/ad...storico_simbolo&simbolo=INAG&fecha=01-02-2018

json response:

[

I use the next piece of code to convert this json to dataframe:

def getFinanceHistoricalStockFromByma(tickerList):
dataFrameHistorical = pd.DataFrame()
for item in tickerList:
url = 'https://www.byma.com.ar/wp-admin/admin-ajax.php?action=get_historico_simbolo&simbolo=' + item + '&fecha=01-02-2018'
response = requests.get(url)
if response.content : print 'ok info Historical Stock'
data = response.json()
dfItem = jsonToDataFrame(data)
dataFrameHistorical = dataFrameHistorical.append(dfItem, ignore_index=True)
return dataFrameHistorical

def jsonToDataFrame(jsonStr):
return json_normalize(jsonStr)


The result of json_normalize is 1 row and a lot of columns. How can I convert this json response to 1 row per list?
