Currency limits

Order types

Buy order / sell order (smth similar to limit order on other exchanges?!)

User can set both price and quantity. (Can be executed partially?!)

Buy market order / sell market order

User can set only quantity of base currency to buy or to sell respectively

Buy market total order / sell market total order

User can set only quantity of quote currency. It's a buy/sell market order for a certain amount.

Example: user sets quantity 100 on the pair BTC/USD. It means he wants to buy BTC for the amount of 100 USD.

Private API request example

import requests

import hmac
import time
import urllib

api_key='API_KEY'
api_secret='API_SECRET'

nonce = int(round(time.time() * 1000))

params = {}
params['nonce'] = nonce
params['pair'] = 'BTC_USD'
params['quantity'] = 5
params['price'] = 5
params['type'] = 'sell'
params = urllib.parse.urlencode(params)

api_secret = bytes(api_secret, encoding='utf-8')

H = hmac.new(key = api_secret, digestmod = hashlib.sha512)
H.update(params.encode('utf-8'))
sign = H.hexdigest()

headers = {
    "Content-type": "application/x-www-form-urlencoded",
    "key": api_key,
    "Sign": sign
}

endpoint = "https://api.exmo.com"
req = "/v1/order_create"

r = requests.post(endpoint + req, data=params, headers=headers)

print(r.text)
