Missing / data delay?

Alpaca Market Data
1

Using alpaca python api. Why do I have the last hour missing in the minute data? Also the data between every 20 minutes is missing. What can I do to get latest data?

symbols = [‘DLA’,‘AAPL’]

datatest = api.get_barset(
symbols=symbols,
timeframe=‘minute’,
limit=30,
end=formatted_time)

datatest['DLA']
