Is there a way to set the fee as a per/byte value, instead of absolute? or is there a way to see the transaction size?

I thought armory's txfees were dynamic?

Based on what calculation?  I'd like to use the recommendation from 21.co

Armory uses the fee from Bitcoin Core's estimatefee RPC function or the one that you set in the transaction. I'm pretty sure it will use whichever is higher.

It should never contact a third party for any information whatsoever.

I will take this to mean the answer to both questions is NO.

hey, no need to get upset. Stick to smiles :)

I'm not upset, frustrated is more like it.  I can't be the only person that wants to be able to set appropriate manual fees.  I'm sure the software must calculate the size of the transaction, why isn't this available to me?  Is this a technical limitation of some sort?

You already know you can use 21.co to choose the level of fee appropriate to your priorities for a given transaction, it's written in one of your posts up the page.

You're finding things to complain about for the sake of complaining, not because you need help. That makes you a troll. Don't troll.

Ok I'm obviously missing something then.  So tell me, if 21.co tells me the best fee is 60 satoshi/byte, how do I use that information to set the fee in Armory?

That'll be 60 satoshis multiplied by 255 bytes then (assuming you're not using > about 5 inputs/outputs)

For me i can only tell you that you can't predict the transactions size before sending it .
But i can tell you how it somehow works ,

2 outputs= 0.0002 fees
4 outputs-  0.0004 fees

and so on , So far this method is the best one for me , Also if the transaction has only one output never put transaction fees lower then 0.0002 . Use blockchain.info new version it sets the fees automatically and mostly times the fees is perfect according to the size of transaction .

Ah, a real answer that may fill in the gap.  So a fee can't be calculated, it can only be guessed.  Strange but thank you.

Don't troll this sub board

He is not trolling imo. I have asked the same question a few times.

I finally figured out (or better, was told) that if you make an unsiged tx, then sign it, then check the raw tx before broadcasting you can see what size it will be.

And you were far more polite, not to mention believable. It's possible it's not a troll, I can accept that, but it's not difficult to end up with false positives on the troll front, we're literally inundated with them on bitcointalk.

I'm sorry if you're frustrated smiles, except, I'm not. It is not appropriate to behave as if the people that could help you are being negligent to your plight; would you help someone who allowed their temper to overwhelm them? Getting involved can be a bad decision for any that might be able to help, so just remember: there is an amount of time before you finish typing and hitting the send button. Use it to review what you wrote, in light of what you really want.

Awesome suggestion thanks, I'll check it out.

sounds like this is what I want to know.
Can you elaborate on this?

My point is that I would like to automate some payments, but I cannot know in advance how many unspend output will be used by the transaction.
As far as I understood, the outputs will be reused following the "first in, first out" policy, and I would like to deduce the transaction fees from the transaction.

so for a given amount, I should make an unsiged tx, sign it and check the raw tx size.
then, compute the amount of fee that I want to spend.
and make another transaction with the appropriate transaction fee.

right?
