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 @ofyzero - Are you getting any particular error message or code?

It would help if you could post your request and response so I can troubleshoot.

Thanks!

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’

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)
