The following code snippet in Research environment plots and returns future contract NGH19 data but only until 2018-11-08:
ng_contracts = symbols('NGH19')
ng_consecutive_contract_volume = history(
ng_contracts,
fields='high',
frequency='daily',
start='2018-01-01',
end='2019-02-07'
)
ng_consecutive_contract_volume.plot();
On TradingView charts, NGH19 plots future contract data up-to-date (incl. today's data). Is Quantopian futures data not available up-to-date for free in Research environment?
