Even if I type "since" keyword in ccxt bitget, always get only the latest information. The same code worked on ftx, what's the problem?
bitget = ccxt.bitget({'apiKey' : self.KEY,
'secret' : self.SECRET_KEY,
'enableRateLimit' : True,
'options' : {'defaultType':'swap'}
})
yyyymmdd = '20220301'
since = int(datetime(int(yyyymmdd[:4]),int(yyyymmdd[4:6]),int(yyyymmdd[6:])).timestamp()*1000)
ohlcv = bitget.fetch_ohlcv('BTC/USDT', '1m', since, limit = 1000)
ohlcv = pd.DataFrame(ohlcv)
ohlcv.columns = ['time','open','high','low','close','volume']
ohlcv['time'] = ohlcv['time'].apply(lambda x : datetime.fromtimestamp(x/1000).strftime('%Y%m%d %H:%M'))
time open high low close volume

How can I get specific time period information ?
