There's these two tools out there that can be really helpful, I believe they are called "a calculator" and "a spreadsheet". The latter works great for me. You should look into it.
Nope,
That's what we pay fees for,
for them to provide a proper platform,
as for the calculator and spreadsheet,
be my guess, sounds like you are from
a antiquated world, sure you still use a "Slide Ruler" even !
The whole idea is to save time,
not create more time,
oh well, you just blew whatever "credibility" with me that you might have had before,
I do believe there is a "Ignore" button here or "Block User" for Dumb-Asses !
Sorry about thoughts aloud here, but you are really rather annoying with your desperation on pushing for this well beyond real significance feature. When I am in my lending phase at Bitfinex, I would really HATE to know that a person like you is taking my swaps.
YOU and like you, are the hell of a lending risk around here.
Are you having some serious math problems? If you really want to dump all your money into position in a flash, is it THAT difficult to make an estimate in your head? Just round the numbers and go. Don't like it, don't "round" just go (elsewhere).
We are paying fees (among lowest in the industry BTW) for the overall (quite well designed in my opinion) trading platform. It has what is needed and already even more.
P.S. I found the button you were referring to. Try to guess (no math here) who is not going to see, whose "Dumb-Ass" posts ...
