Question

Cette fois, je souhaite acheter 50 contrats USD_CAD au prix actuel du marché
Procédure :
demandes d'importation
importer json

Afficher le taux de change actuel USD_CAD-------------------------------------------- -- ------------------------------------------------ --

url = 'https://api-fxpractice.oanda....'

headers = {'Autorisation':'Bearer '+access_token}
r = requêtes.get(url,headers = headers, params=params)
prix = r.json()
print(prix)

Achetez 50 contrats USD_CAD au prix actuel du marché---------------------------------------- ----- -----------------------------------------------

url = 'https://api-fxpractice.oanda....' #5898545 fait partie du compte 101-011-5898545-001

Le deuxième rapport d'erreur du programme :
{"code" : 4,"message" : "Le jeton d'accès fourni ne permet pas d'effectuer cette requête","moreInfo":"http://developer.oanda.com/docs /v1/auth/#overview"}
{'message' : 'Le jeton d'accès fourni ne permet pas d'effectuer cette requête', 'moreInfo' : 'http://developer.oanda.com/do...' , 'code' : 4}
Mais il n'y a aucun problème avec le jeton d'accès grâce au fonctionnement normal du premier programme. En même temps, il y a une liste d'erreurs sur http://developer.oanda.com/do. . Liste d'erreurs

Ci-joint un document de la société oanda :
import http.client
import urllib
import json
import datetime

Ce fichier contient quelques appels très simples à l'API OANDA

Cela indique que si le seuil est dépassé, obtenez le prix actuel de l'instrument et effectuez une transaction

def checkAndTrade() :

conn = httplib.HTTPSConnection("api-sandbox.oanda.com")
conn.request("GET", "/v1/prices?instruments=USD_CAD")
response = conn.getresponse()
resptext = response.read()
if response.status == 200:
    data = json.loads(resptext)
    if data['prices'][0]['ask'] > 0.994:
        headers = {"Content-Type" : "application/x-www-form-urlencoded"}
        params = urllib.urlencode({"instrument" : "USD_CAD",
                                   "units" : 50,
                                   "type" : 'market',
                                   "side" : "buy"})
        conn.request("POST", "/v1/accounts/8026346/orders", params, headers)
        print(conn.getresponse().read())
else:
    print(resptext)

Cela crée un ordre avec le même prix que ci-dessus, et la transaction sera exécutée lorsque le prix franchira 0,994

ordre def() :

now = datetime.datetime.now()
expire = now + datetime.timedelta(days=1)
expire = expire.isoformat('T') + "Z"    
conn = httplib.HTTPSConnection("api-sandbox.oanda.com")
params = urllib.urlencode({"instrument": "USD_CAD",
                           "units" : 50,
                           "price" : 0.994,
                           "expiry" : expire,
                           "side" : "buy",
                           "type" : "limit"})
headers = {"Content-Type" : "application/x-www-form-urlencoded"}
conn.request("POST", "/v1/accounts/8026346/orders", params, headers)
print(conn.getresponse().read())

Ce programme est peut-être plus ancien et son adresse API est différente de l'adresse API actuelle

Answer 1

Les comptes ont l'autorisation de lire les données, mais peuvent ne pas avoir l'autorisation de passer des commandes
Les problèmes que vous rencontrez actuellement sont tous liés à des éléments de l'API. Vous devez étudier attentivement la documentation de l'API, sinon vous rencontrerez d'innombrables problèmes similaires à l'avenir

.

À moins que quelqu'un ne soit familier avec cette API, je ne peux pas vous aider. ＝＝＝＝＝＝＝＝＝
Si vous commandez et surveillez depuis le site Web, vous constaterez que votre URL et vos données sont complètement différentes de celles du site Web

url = 'https://api-fxpractice.oanda.com/v3/accounts/101-011-5898545-001/orders'
headers = {'Content-Type' : 'application/json','Authorization':'Bearer '+access_token}
data = {"order":{"instrument":"EUR_USD","type":"MARKET","units":"1"}}
req = requests.post(url,json=data,headers=headers)
