Hello, I just started working with finnhub moving from yfinance. It's returning the wrong data, the data I ask for is today and up to 200 days back, but instead I get odd numbers like 128 days back or 228 days back, and the start and end times are completely wrong. Here's my "hello world", it has a unfinished function in the middle (functionmovingaverage), but it's just a rough unfinished program. I have a long list of crpytocurrencies reading out of a text file (CryptoList.txt)

starttime = datetime.datetime.now() - datetime.timedelta(days = 200) currenttime = datetime.datetime.now() - datetime.timedelta() starttimestamp = int(starttime.timestamp()) currenttimestamp = int(currenttime.timestamp())
print(starttimestamp) print(currenttimestamp) cryptolist = open("CryptoList.txt")
fc = finnhub.Client(api_key="cjsjv99r01qm5ielfq1gcjsjv99r01qm5ielfq20")

for i in cryptolist.readlines(): fixedi = i.split('\n')[0] name = fixedi print(name) res = fc.crypto_candles(name, 'D', starttimestamp, currenttimestamp) dataframe = pd.DataFrame(res) functionmovingaverage(dataframe) time.sleep(1)
