Hello,

When running python code

#!/usr/bin/env python
import logging
from binance.cm_futures import CMFutures as Client
from binance.lib.utils import config_logging
from binance.error import ClientError

config_logging(logging, logging.DEBUG)

key = “”
secret = “”

client = Client(key, secret, base_url=“https://testnet.binancefuture.com”)

try:
response = client.new_order(
symbol=“BTCUSD_PERP”,
side=“SELL”,
type=“LIMIT”,
quantity=0.005,
timeInForce=“GTC”,
price=44000,
)
logging.info(response)
except ClientError as error:
logging.error(
“Found error. status: {}, error code: {}, error message: {}”.format(
error.status_code, error.error_code, error.error_message
)
)

it returns

DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): testnet.binancefuture.com:443

For Coin margin futures, the filters of BTCUSD_PERP is

                {
                    "stepSize": "1",
                    "filterType": "LOT_SIZE",
                    "maxQty": "1000000",
                    "minQty": "1"
                }

so the quantity should has no decimal; one contract values 100 USD.
