JSON error when submitting OSO order

I am not sure if my OCO order has all the correct fields. I am trying to test this, but I get an Invalid JSON: illegal number, offset: 0x00000114 JSON error. I am using Python examples from supahcullen/**[Tradovate-Python-Client]. I have this one script I created for a StopOrder with a StopLoss and TakeProfit for testing.

Here is the code. Some variable values are imported and not shown.

#Place TV Stop limit order
import requests
from GetAccessToken import getAccessToken
from config import *
import time

Be careful with this one! It will submit an order!

buysell must be either “Sell” or “Buy”

def placeStopLimitOrder(live, Qty, buysell, orderPrice, stoploss, takeProfit, token):
“”"Places StopLimit order with quantity “Qty”, direction “buysell”, price “orderPrice”, and includes StopLoss and TakeProfit

    live (bool): True = live, False = demo
    Qty (int): Quantity of contracts you want to buy
    buysell (string): "Buy" or "Sell"
    orderPrice (int): Price you want the order at

    int: orderId of order you just placed
ocoDirection = ""
if buysell == "Buy":
  ocoDircetion = "Sell"
  ocoDirection = "Buy"
header = {
    'Authorization': f'Bearer ${token}', 
    'Accept': 'application/json'

if live:
    url = "https://live.tradovateapi.com/v1/order/placeorder"
    url = "https://demo.tradovateapi.com/v1/order/placeorder"

order = { 
            "accountSpec": USER_NAME, //imported value

            "action": buysell,

            "isAutomated": "true",
            "bracket1": {
                "action": ocoDirection, //For some reason this is empty
                "orderType": "Stop",
                "price": stoploss,
                "timeInForce": "GTC"

                "timeInForce": "GTC"

# Make request
res = requests.post(url, headers=header, data=order)

# Error stuff
if res.status_code != 200:
    print("StopLimit Order Failed")

orderId = res.json()['orderId']

return orderId

This is the error I get back.

What am I missing?? :slight_smile:

I fixed this issue. The values I supplied were not correct or in the right place. Once fixed, I created a new script to place an OCO order with a Take Profit and Stop Loss. The endpoint changes from “placeorder” to “placeOSO” the new order structure that works for this is:

bracket1 = {
        "action": ocoDirection,
        "orderType": "Limit",
        "price": takeProfit
bracket2 = {
        "action": ocoDirection,
        "orderType": "Stop",
        "stopPrice": stoploss

order = {
      "accountSpec": USER_NAME,
      "accountId": accId,
      "action": buysell,
      "symbol": SYMBOL,
      "orderQty": Qty,
      "orderType": "StopLimit",
      "price": orderPrice,
      "stopPrice": orderPrice,
      "isAutomated": True,
      "bracket1": bracket1,
      "bracket2": bracket2

token = getAccessToken(False)[0]
print(placeStopLimitOrder(False, 1, “Buy”, 3977, 3976.50, 3977.50, token))

ENTRY = 3977
STOPLOSS = 39766.50
TAKE PROFIT = 3977.50

This will place a Stop Limit order with Take Profit and Stop Loss above or below the current market price.

ocoDirecion = The opposite of the value buysell direction //The variable name should be osoDireection, but it can have any name.
takeProfit = The Take Profit price
stoploss = The Stop Loss price
accid = The Account ID
SYMBOL = The Market being traded
Qty = The quantity
orderPrice = The Entry price
isAutomated = This was in “” and needed to not have quotes -Flag for automated trading

Hey Will,
When you were having this issue did it result in a code 400 bad request error? Having a similar issue and cant for the life of me figure it out

Just to save anyone in the future on placing oso/oco orders via python (super simplified version)
