wish: internal transfer with different currency

Hello @kiddo,

This has already been discussed in issue #552565 more specifically in these two comments : https://bugs.launchpad.net/homebank/+bug/552565/comments/35 and https://bugs.launchpad.net/homebank/+bug/552565/comments/41

At the time Maxime didn't wanted to delay the release of multi-currency as it has been a long time requested feature.

I am not sure if he's willing to implement this in homebank as he argued that most users are not interested by this. I had a look at the code to see if I could help but the architecture seems quite complicated and it is not clear how difficult this would be to implement.

@mdoyen would you consider adding xfer in different currencies to homebank ?

Take care

So the need is to enable a xfer that keep (sealed) the exchange rate from source to target ?
Or is that more complex?

I'm not 100% sure what you mean by "enable a transfer that keeps/seals the exchange rate from source to target", but here's what I want in other words:

- a transaction "type" that links two transactions with differing amounts (ex: 100 USD in one transaction linked to the corresponding 130 CAD transaction in a different account). Basically like the existing "Internal transfer" transaction type/feature, but allowing for diverging amounts and currencies on the two linked transactions.

- for those two transactions to not be counted in the statistics (or to have some sort of treatment that doesn't skew the stats like it does right now)

If that's what you're asking: no need to have homebank calculate forex, I just want to enter both amounts manually (because that's dependent on my banks etc., so I take whatever amounts they give me). No need for me to enter/use an exchange "rate", even; just input currency1 amount, output currency2 amount...

So in times of *very* volatile cryptocurrencies, I think this is really important. :D

So currently you can already add an exchange rate, but to the currency, not to the transaction, so this may be the "only" thing, which needs to be changed.

See https://bugs.launchpad.net/homebank/+bug/1749473 for my bug report.

Hi! Just wanted to say that I really need it feature in HomeBank!
Without option to transfer money between accounts in different currencies, the statistics shows wrong things...

Anyway, thanks a lot for HomeBank!

What maybe a compromise is to implement this the way it is in mmex (money manager ex).

=> For a xfer you have an advanced mode when you can input a different value by yourself for the target account, and so have different amount.

What do you think guys ?

That could work I guess, especially if there's a way, when exporting to CSV with homebank, for Homebank to automatically calculate the exchange rates based on the two (source and destination) amounts of the "advanced" transaction (since the "accounts" have the notion of currency anyway)

Don't exactly understand it, but instead of manually entering a different value for the currency, it can, of course, (by default) take the currency conversion one you entered in the currencies window of HomeBank.

@rugk: this is obvious that the amount would be prefilled in that case

This feature would be neat!

I Am voting for this feature. The different currencies in internal transactions with entering values manually should be enough for the start. HomeBank is best.

Having this feature even with manual entry would be very good.

I do not know how to upvote for this wish, but I would like to upvote for it.

I am for this feature!
So that we can edit the internal translation (as it is done in MMEX)

+1 from me for an idea:)

I make a lot of transfers between GBP, EUR and PLN and would be nice if would be in "Add transaction/transfer" option to type input amount and output amount in second currency, or typing exchange rate of the transaction. For now I just have to make manually two transactions - on first account as 'Expense' and on another as 'Income' and put details (description etc) of transaction two times, adding also categories to them (sample attatched). Ok, it's fine when you have just efx from time to time. But not when efx transactions are often xD

Anyway very goob job with the app! And keep it up!

I think the easiest way to implement this is to allow different amounts for the two sides of the transfer transaction when the transaction is between accounts in different currencies. This would imply the transaction FX rate, but would avoid the issues with precision and rounding associated with the FX calc. I.e. if user transfers 100 EUR into a USD account, the transaction screen would ask to enter a USD amount as well. If the FX rate was 1.2345, the user would then enter 123.45 USD.

Looking at the code, the Transaction type currently has kxfer and kxferacc members. The code then enforces consistency that currency of kacc and kxferacc is the same. If we can add kxferamount member, we'll be able to accomodate cross-currency transfers. If currency of kacc != currency of kxferacc, the transaction amount in kxferacc will come from kxferamount rather than amount.

I put together a basic proof of concept patch against 5.4.3 source. This allows entering and saving cross-currency transactions. For a cross-currency transaction, the user needs to enter amounts for both sides. I.e. +500 EUR / -600 USD to convert USD into EUR.

This patch is in no way complete, but hopefully can serve as a basis for discussion. (I'm very keen to get this feature in Homebank, since my current financial software keeps me from migrating to Wayland).

@LB: yes indeed, the way mmex implement this is just
- a checkbox that break the link that share the same amount between the from and to txn, and enables store 2 amount.
I will review the patch when working on this.

I am totally new to Home Bank, looking to migrate from an obsolete money manager. What I have tried up to now is to import old files but I can't set the correct currency to each account because of the internal transfers between accounts with different currencies. The proper management of multi currency is putting me off for now.
