Placing orders (buy/sell) for funds

[tux2000]

Hej.

I was looking for functionality to buy and sell funds using this library. To what I could see this functionality is not yet available and the function place_order is limited to instruments like stocks and certificates that are traded on an exchange.

In the website the API endpoint I am looking for is https://www.avanza.se/_api/fund-guide/fund-order-page/buy with the request payload being for example: {"orderbookId":"56127","accountId":"NNNNNNNN","amount":"100","orderbookName":"Simplicity Likviditet A"}

I assume the corresponding endpoint is available in the mobile API too and thus hopefully this should be possible to implement.

Haven't yet reached the point to testing place_order in production yet but when skimming through the code I dont see any restrictions for the type of order. Just specify which instrument by order_book_id:

avanza/avanza/avanza.py

Line 1476 in 3f3a4c5

order_book_id: str,

I tried using the place_order function but got stuck with price and volume (required by the function) vs amount (entered as only quantity on the website)

Ah yeah your’e right, its a whole different endpoint

For the one implementing this in the future:
Looks like its 2 requests

1. POST https://www.avanza.se/_api/fund-guide/fund-order-page/buy Payload {"orderbookId":"512559","accountId":"<accountId>","amount":"100","orderbookName":"Handelsbanken Hållbar Energi A1 SEK"} Response {"orderRequestStatus":"SUCCESS","orderId":<orderId>,"message":"","accountId":"<accountId>"}
2. POST https://www.avanza.se/_api/fund-guide/fund-order-page/order Payload {"accountId":"<accountId>","orderId":<orderId>} Response {"visibleOnAccountDate":"2021-05-17","stopTime":"2021-05-14T13:00:00"}

I added fund buying functionality in a new function place_order_buy_fund on this branch: https://github.com/tux2000/avanza/tree/fund_orders

This is not elegant yet and should probably be tested more. But it worked to send a buy order for a fund that showed up on the Avanza website. Only the first request from @warna720 's comment (#31 (comment)) seems to be strictly needed. And I left out the orderbookName in the request payload...

Maybe it helps with a proper implementation...

Here are some details for the sell call to the API (as performed by the website):

Two requests:

1. POST https://www.avanza.se/_api/fund-guide/fund-order-page/sell
   Payload: {"orderbookId":"56127","accountId":"<accountId>","volume":1.241047,"orderbookName":"Simplicity Likviditet A","nav":112.82}
   Response: {"orderRequestStatus":"SUCCESS","orderId":<orderId>,"message":"","accountId":"<accountId>"}

2. POST https://www.avanza.se/_api/fund-guide/fund-order-page/order
   Payload: {"accountId":"<accountId>","orderId":<orderId>}
   Response: {"visibleOnAccountDate":"2021-05-24","stopTime":"2021-05-20T13:00:00"}

[warna720]

Huh, so both volume and amount works in the first request works?

[tux2000]

The requests in my comment are for a sell transaction, while your request examples in #31 (comment) is for a buy transaction.

[warna720]

Ah got it. Will you make a PR soon btw?

[tux2000]

I might want to refactor the code a bit and I would like to have both buy and sell working before doing a pull request. But of course anybody is more than welcome to use what already is present in my fork to speed up an implementation...

[tux2000]

Now I also implemented a function to sell funds shares. Its available at https://github.com/tux2000/avanza/tree/fund_orders

Deleting of fund orders is possible with the already available function delete_order

[warna720]

Nice job!

[tux2000]

Not really happy yet with introducing two more functions but it works for now. I will send a pull request in a minute to start the discussion how this can be included in upstream...
