Trading Error for "order_buy_market" and "order_sell_market"

[cpasean]

Encountered error messages since 2 weeks ago: (robin-stocks ver: 3.0.4)

rs.order_buy_market('AAPL', 1) Error in request_post: Expecting value: line 1 column 1 (char 0)

rs.order_sell_market('AAPL', 1) {'non_field_errors': ['Your app version is missing important stock trading updates. You can still place orders on the web.']}

I will be grateful to have your advice ASAP, please help.

getting the same error this morning...

This is directly related to the orders.order() method. I am still figuring it out on my end but every method that includes placing orders always calls orders.order, which as of robin_stocks 3.0.4 includes a modified payload.

The problem lies in the payload itself, but I am still figuring out how to modify the payload to provide the correct set of parameters.

This is the method underlying all the other order methods:

@login_required
def order(symbol, quantity, side, limitPrice=None, stopPrice=None, account_number=None, timeInForce='gtc', extendedHours=False, jsonify=True):
    """A generic order function.

    :type side: str
    :param limitPrice: The price to trigger the market order.

    :param timeInForce: Changes how long the order will be in effect for. 'gtc' = good until cancelled. \

    url = orders_url()

    data = request_post(url, payload, jsonify_data=jsonify)

    return(data)

That's what I have so far but I am still working on fixing the payload.

Hey, Check out the pull request and my post on this issue #379 discussion where this issue has been going on...

[sanathnair09]

So today I received the same error when trying to do an order_buy_market. I added breakpoints and took a look at where the error was being raised from and these were my findings.

Error is raised from helper.py Line 353 (the except block)

def request_post(url, payload=None, timeout=16, json=False, jsonify_data=True):
    data = None
    res = None
    try:
        if json:
            update_session('Content-Type', 'application/json')
            res = SESSION.post(url, json=payload, timeout=timeout)
            update_session(
                'Content-Type', 'application/x-www-form-urlencoded; charset=utf-8')
        else:
            res = SESSION.post(url, data=payload, timeout=timeout)
        data = res.json()
    except Exception as message:
        print("Error in request_post: {0}".format(message), file=get_output())
    # Either return response <200,401,etc.> or the data that is returned from requests.
    if jsonify_data:
        return(data)
    else:
        return(res)

Essentially what is happening is that when an order_buy_market or sell is called the server responds with an HTTP 500 error. (making a speculation here but I'd assume this issue really occurs whenever the def order(symbol, quantity, side, limitPrice=None, stopPrice=None, account_number=None, timeInForce='gtc', extendedHours=False, jsonify=True) order method is called)

And then when the line data = res.json() is called, a JSONDecodeError is raised because the formatting of the 500 response doesn't seem to follow the guideline. (I'm not well versed in JSON standards but it seems the field doc was causing the issues.)

• PR to fix this issue: https://github.com/jmfernandes/robin_stocks/pull/403 @jmfernandes

It adjusts the order payload params due to recent Robinhood API changes , and works for both market buy/sell stocks orders : Market Buy : Market Sell :

• correct the fractional orders after the merges
• load stock open orders list by account_number
• add 500/400 debug info
• Bonus : trade 24 hours stocks markets ! 😆

Would you elaborate on how you cleared the error and made the order by sharing your code more in detail? Please...

[henryzhangpku]

Sure , here is my PR where you can see all my code fix : https://github.com/jmfernandes/robin_stocks/pull/403

RHS api is really all about REST. Open your chrome console , place a trade via web (100% working), and from console/Network you will see the POST request sent to RHS /orders url. Comparing the actual working POST request/payload to the code , you will see what params have been removed/added by RHS in their new API version/POST request. From that you get the answer to get it working .

I really appreciate your tips. I got Buy Order fixed, but still struggling with Sell-order:

order_sell_market('BIIB', 1) {'non_field_errors': ['Invalid Good Til Canceled order.']}

Would you help me with fixing this 'non field errors'?

My PR has both buy/sell working. Take a look at my PR.

Will the PR 403 get merged soon? I cannot run it and am unable to follow the PR to change my code. Thanks.

@henryzhangpku

thanks for the scripts, this code in my computer: "url = orders_url() always shows: it's not defined",could you please help me with this ? thanks

[Adelantado]

robin-stocks 3.0.5 has been out for a few days. Hope it helps.

[paraluke23]

No, 3.0.5 doesn't fix the issue: Error in request_post: Expecting value: line 1 column 1 (char 0)

Can you share more details of this error ? I can help you out.

@henryzhangpku, nice work, but you seem to have forgotten to update the docstring, which would keep people from having to come fish around here in the issues to find out how this works. Also, market_hours in snake-case seems inconsistent with the extendedHours argument in camel-case, but maybe it's too late to change now to avoid breaking peoples' code. Anyway, thanks for the fix!

[henryzhangpku]

Np. One thing you should note is this API changes (from RH side obviously) , so from time to time the parameters have to be updated . I had a few recent changes on my end as well , with that I have 24 hours market 100% working.
