如何使该Python脚本增加对使用API​​进行交易的限制?

我正在整理一个python脚本以使用API​​在poloniex上进行交易,到目前为止,我已经在满足某些条件时进行了交易,但是我仍然需要它不再进行其余交易那天(我的整个脚本每60秒循环一次)。

到目前为止,我有这个脚本:

import requests
import urllib.request
import urllib.parse
import http.client
import hashlib
import hmac
import time
import json
from urllib.request import urlopen

The_Currency_Pair = input('Which Currency Pair?\nPAIRS TO CHOOSE FROM:\nUSDT_BTC\nUSDT_XRP\nUSDT_ETH\nUSDT_BCH\nUSDT_STR\nUSDT_LTC\nUSDT_ETC\nUSDT_XMR\n')


api = 'https://poloniex.com/tradingApi'
key = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
secret = 'XXXXXXXXXXXXXXXXXXXXXXXXX'


def main():
    poloniexPrices = urlopen('https://poloniex.com/public?command=returnTicker').read()
    poloniexjson = json.loads(poloniexPrices)
    poloniexlastP = poloniexjson[The_Currency_Pair]['last']


    poloniexOCHL = urlopen('https://poloniex.com/public?command=returnChartData&currencyPair=USDT_BCH&start=1538352000&period=86400').read()
    poloniexOCHLjson = json.loads(poloniexOCHL)
    poloniexlasthigh = poloniexOCHLjson[-2]['high']


    print ('Last Price')
    print (poloniexlastP)
    print ('----------------------------------------')
    print ('Last Day High')
    print (poloniexlasthigh)
    print ('----------------------------------------')



    data = {
        'command': 'returnBalances',
        'nonce'  : int(time.time() * 1000)
    }
    data = urllib.parse.urlencode(data).encode()

    signature = hmac.new(secret.encode(), data, hashlib.sha512)

    headers = {
        'Key' : key,
        'Sign': signature.hexdigest()
    }

    request = urllib.request.Request(
        url=api, data=data, headers=headers, method='POST'
    )

    text = urllib.request.urlopen(request).read().decode()

    print ('MY ACCOUNT BALANCE')
    try:
        print(json.loads(text)['USDT'])
    except:
        print(text)
    print ('-----------------------------------------')



    if float(poloniexlastP) > 0:
        print ('PLACING TRADE')
        print ('-----------------------------------------------')

        parms = {"command":"buy",
             "currencyPair":The_Currency_Pair,
             "rate":100,
             "immediateOrCancel":1,
             "amount":0.01,
             "nonce":int(time.time() * 1000)}

        parms = urllib.parse.urlencode(parms).encode()

        signature = hmac.new(secret.encode(), parms, hashlib.sha512)

        headers = {'Key' : key,
                   'Sign': signature.hexdigest()}

        request = urllib.request.Request(
        url=api, data=parms, headers=headers, method='POST')

        text = urllib.request.urlopen(request).read().decode()

        ordernumber = (json.loads(text)['orderNumber'])

        print ('Order Number:')
        print (ordernumber)




while True:
    main()
    time.sleep(60)

无论如何,在进行交易后,我需要确保60秒的睡眠后,除非进行了新的一天/交易完成的第二天,否则就不会进行第二次交易。 (我可以为此使用poloniex服务器时间吗?)

因此,如果它已经达到print (ordernumber),则表示已经进行了交易。但是,如何将其标记为当天或某天的交易,并在if float(poloniexlastP) > 0:中将其用于下一个循环,以确保它不会再进行其他交易?

2 个答案:

答案 0 :(得分:0)

您可能想要重置某种标志。也许遵循以下原则:

        print ('Order Number:')
        print (ordernumber)
        return True # You've made a trade
    return False # You've didn't make a trade


have_traded = False
while True:
    if not have_traded:
        have_traded = main()
        time.sleep(60)

    if new_date_function():
        have_traded = False

答案 1 :(得分:0)

如果您正在使用Flask之类的应用服务器,则可以轻松设置限制器

from flask_limiter import Limiter

app = Flask(__name__)
limiter = Limiter(app, global_limits=["100 per hour", "20 per minute"])

然后可以使用定义的限制器装饰每个端点:

@app.route("/slow")
@limiter.limit("1 per day")
def slow():
    return "24"

@app.route("/fast")
def fast():
    return "42"

@app.route("/ping")
@limiter.exempt
def ping():
    return 'PONG'
