Can someone please help me with this. I have a valid Brokerage account but it still gives me this error.

I also have this issue using Python 3.8.2. Tried changing the HTTP endpoints in the rest.py, but have not been able to get it to work. Using Postman, I can GET and POST to Alpaca using https://paper-api.alpaca.markets/v2/ as my endpoint. However, the algo still does not have the right endpoints and updating rest.py with different urls has not fixed it. Any help will be appreciated.

I'm also having this same issue: HTTPError: 404 Client Error: Not Found for url: https://api.polygon.io/v1/historic/agg/minute/

[erod998]

This may be completely wrong, but I believe the V2 looks like this: Calling API: minute_history[symbol] = api.polygon.historic_agg_v2( timespan="minute", symbol=symbol, limit=1000, multiplier=1, _from='2020-04-05', to='2020-04-06' ).df

Updated polygon code.

The API now has a v2 function: def historic_agg_v2(self, symbol, multiplier, timespan, _from, to, unadjusted=False, limit=None): path = '/aggs/ticker/{}/range/{}/{}/{}/{}'.format( symbol, multiplier, timespan, _from, to ) params = {} params['unadjusted'] = unadjusted if limit: params['limit'] = limit raw = self.get(path, params, version='v2') return Aggsv2(raw) Obviously the dates cannot be hardcoded into the api call but I was testing it, I don't know if this is the right step in the right direction.

This was the fix. Nice work, and thank you.

It was running up until this error occurred: TypeError: 'NoneType' object is not iterable

I also got that error. Can't figure it out yet as it does not happen each time the algo is ran. I am not sure if the GET request is getting the wrong info or if the JSON isn't being parsed correctly. The current way I call the V2 API is incredibly slow. Not sure if it is the code or if its limitations of the API. Takes about 5 minutes to populate the list of the aggregated data.

This is the response from GET https://api.polygon.io/v2/aggs/ticker/AAL/range/1/minute/2020-04-01/2020-04-06?apiKey=xxxxxxxxxxxx. { "ticker": "AAL", "status": "OK", "queryCount": 3241, "resultsCount": 3241, "adjusted": true, "results": [ { "v": 1761, "vw": 11.727, "o": 11.81, "c": 11.5, "h": 11.81, "l": 11.5, "t": 1585728000000, "n": 23 }, { "v": 600, "vw": 11.5, "o": 11.5, "c": 11.5, "h": 11.5, "l": 11.5, "t": 1585728060000, "n": 9 },...............

here's the code for capturing the time if that's what you were looking for?

I'm getting a different error this time. Could it be because I have it using a paper trading API key?

Now I'm getting an error "Cannot close a running event loop." Do you have any thoughts on this? [image: image.png]

Added generation of yesterday/today dates to the historical data function using api.polygon.historic_agg_v2 of the API, that was mentioned here: #https://github.com/alpacahq/Momentum-Trading-Example/issues/14#issuecomment-610522457

#add date to imports
from datetime import date, datetime, timedelta

def get_1000m_history_data(symbols):
    print('Getting historical data...')
    minute_history = {}
    c = 0
    today = date.today()
    yesterday = date.today() - timedelta(days=1)

    for symbol in symbols:
        minute_history[symbol] = api.polygon.historic_agg_v2(
            timespan="minute", symbol=symbol, limit=1000, multiplier=1, _from=yesterday.strftime("%Y-%m-%d"), to=today.strftime("%Y-%m-%d")
        ).df
        c += 1
        print('{}/{}'.format(c, len(symbols)))
    print('Success.')
    return minute_history

I am also having this issue but I can't seem to figure out what you did to fix it
