Hi ,  
I am trying to calculate ema(55) using hourly market data. But I couldn’t get the last 55 hourly bar. Is there any one help me? I am using market data v2.

Thanks ,

Omer

hi, sorry for the late response. Here is my code:

import alpaca\_trade\_api as tradeapi

from alpaca\_trade\_api.rest import REST, TimeFrame

import datetime

import pytz

APCA\_API\_KEY\_ID = ‘’

APCA\_API\_SECRET\_KEY = ‘’

APCA\_API\_BASE\_URL = ‘[https://paper-api.alpaca.markets](https://paper-api.alpaca.markets)’

api = REST(APCA\_API\_KEY\_ID,APCA\_API\_SECRET\_KEY,APCA\_API\_BASE\_URL)

UTC = pytz.timezone(‘UTC’)

# Get daily price data for AAPL over the last 5 trading days.

curr = datetime.datetime.now(tz=UTC)

curr = curr - datetime.timedelta(days=8)

aweek = curr - datetime.timedelta(minutes=15)

curr\_date = str(curr.year) + “-” + ‘{:02d}’.format(curr.month) + “-” + ‘{:02d}’.format(curr.day)

aweek\_date = str(aweek.year) + “-” + ‘{:02d}’.format(aweek.month ) + “-” + ‘{:02d}’.format(aweek.day)

print(curr\_date, aweek\_date)

barset = api.get\_bars(‘AAPL’, TimeFrame.Minute,aweek\_date,curr\_date, limit=100,adjustment=“raw”)

print(barset)

aapl\_bars = barset[‘AAPL’]

print(aapl\_bars)
