Frequently Asked Questions

How safe it is to login with Binck ?

Using the OAuth from Binck, we only have access to a few features (read orders, make orders and get quotes).

We can't do anything else, and we don't get any information about you except the Binck IBAN attached.

We only save your accountId and the ids of the instrument you want to invest in.

Your token is valid only for 24 hours max. We even dump it after 30 minutes.

It is fully automated ?

With Binck, you will need to access this site, or the Binck website, every time you want to invest. We will send you a mail when you need to login, you will need to click one button and the order will be made. You will have to connect when the market is open to make your order for now. We don't handle limit orders.

When can I use this with other brokers ?

The roadmap is not public yet, for now contact me at basile@harmonycalls.com to know more.

Does it work with crypto brokers ?

It will yes ! Next integration will be with Coinbase Pro, Binance and Kraken.

How is it free ?

It's only a hobby project and I don't need to make money from it now. However, in the future I will start getting bills from my hosting and infrastructure so I will start a pricing plan.

Am I safe from over-buying, selling stocks, etc. ?

Can't tell for sure but for now everything needs a verification from your part. The worse that can happens for you is that it buy too much stock (can't use more than the cash you have on your Broker) - It won't happen.

We don't sell anything nor do anything else that read and create buy orders.

What if I want other investment strategies ?

For now this tool only does Dollar Cost Averaging strategy, in the future it will do rebalancing for example.

Will it make me money ?

We expect from you a certain investment culture, if you are reading this question seriously, you are probably not ready.
