This is the part of the python script.

if 0 < i < noSteps:
    order = (client.LinearOrder.LinearOrder_new(side=side, symbol="BTCUSDT", order_type="Limit",
                                                qty=allocatedQuantities[i], price=priceArray[i],

                                                take_profit=takeProfits[i]).result())
    print(order)
    temp_order = order[0]['result']['order_id']
    ordersArray.append(temp_order)

Answer 1

The result key in your order[0] object points to None

You can't sub script a None

Instead of this:

temp_order = order[0]['result']['order_id']

You are effectively doing this:

temp_order = None['order_id']

{
    'ret_code': 130021, 
    'ret_msg': 'oc_diff[1629161425000], new_oc[1629161425000] with ob[0]+AB[96730135992]',
    'ext_code': '',
    'ext_info': '',
    'result': None,   # <---- This is causing your problem
    'time_now': '1645296976.390693',
    'rate_limit_status': 98,
    'rate_limit_reset_ms': 1645296976387,
    'rate_limit': 100
}
