mircea_popescu: i dunno, imo for bitcoin nonvoting divcarrying equity is way better
than
the other way around.
smickles: confuse ppl, raise funds, what's
the difference j/k
smickles: in
the event of an unfavorable liquidation,
they would be paid after
the creditors, but before
the non equity shares
smickles: people who want a say in
the actions of s2, and
smickles: either
that, or raise
the nav by issuing equity bearing shares which pay no dividend
smickles: i kinda want s2
to issue a bond
smickles: well, wouldn't a fund have equity stakes in
the banks?
smickles: s²c, people bought non-equity shares, we placed
the proceeds with various people who lend btc
to people, we pay
the received interest as dividends
to
the shareholders
smickles: mircea_popescu: zt came off
that what
to me when he was 'no longer working at bitcoinica, but doing stuff for
them' for months
smickles: i'm not going
to work on improving my algo on
that stuffs until i get smex done
mircea_popescu: and not all
the
trade volume is necessarily an open long position.
smickles: with positions set which essentially equiate
to a 4x leveraged lon positon
mircea_popescu: smickles while it's
true
that 0.9x is dim, i don't
think 0.9x is a requirement. pretty much 2-3 strikes away from atm is dim afaic.
smickles: dim is supposed
to be -0.999 or something like
that
smickles: not
technically at a delta of -0.88
smickles: mircea_popescu: i'd like
that, right now you don't offer a deep in
the money put
mircea_popescu: i was considering getting maybe up
to 30 strikes next month. esp if we keep climbing or at least hold
mircea_popescu: i can't use my own bot
to decide what
the market says now can i.
mircea_popescu: smickles delta is not a reflection of mkt demand unless
the prices you use are issued by
the mkt
dub: I'm dolly parton next
to
taht
smickles: mircea_popescu: well, i
think
that
the P200T delta is fair, but
the fact
that it's not -0.999 or lower would seem
to imply market demand for options striking higher
dub: that is some itti bitti
titties
mircea_popescu: copumpkin> actually interacting with gpg isn't so bad, btw, if you just pipe commands
together <<< most people find it's quite painless, esp if
they have pympex. its one of
those cases where
the vixen looks sullen but she's quite charming once you get
to know her.
smickles: (based on
the current bids on
the calls)
smickles: so
the delta on P200T is -0.88~
copumpkin: Insufficient funds. You need at least 1101361573.37BTC
to cover
these.
copumpkin: actually interacting with gpg isn't so bad, btw, if you just pipe commands
together
copumpkin: show me
the required amount dammit :P
copumpkin: I know you're calculating
the required amount
to show me
that message
copumpkin: you
take user-unfriendly
to
the next level in your UI :P
sgornick_: So when O.BTCUSD.C140T shows n/a for Last means not a single $14 CALL option was bought? Seems unlikely nobody wanted
to.
mircea_popescu: i can change
them any
time so it's not such a big deal either way i don't
think.
mircea_popescu: seems a
tad confusing. i dunno, maybe i made a bad choice but it seemed
to me more comfortable / intuitive esp for beginners.
sgornick_: > N becomes
T, not
the other way around <--- Ya, dyslexic.
smickles: mircea_popescu: well, shouldn't
the highest available call have a delta of (practically) 1?
mircea_popescu: some systems use a sort of
technique kinda akin
to url shortening
too.
mircea_popescu: sgornick_ well other option systems might spell out
the month in
the options name, or use fixed month letters
sgornick_: Is
that how other options systems work?
sgornick_: Well, I mean does my holdings of
T become holdings of N on
the last Friday of
the month?
smickles: mircea_popescu: you know,
the 20 doesn't have a delta > 0.999
mircea_popescu: but barring significant moves of price
they just remain
the same.
mircea_popescu: sgornick_ in general
the symbols stay
the same. due
to
the explosion of btc i retired
the halfdollar symbols and added 11
through 20 dollars instead. i have
the ability
to do
this as needed.
sgornick_: > "All options expire on
the last minute of
the last Friday of
their month (UTC
times)."
sgornick_: Does
the symbole change each month for
the options?
mircea_popescu: Also Bitcoinica was losing money because its hedging algorithm was
too simple, and during
the last few months
the site had negative profit.
smickles: anyway, what i meant is
that i read about using computation
time sidechanel attacks in relation
to cracking some crypto
smickles: huh, what's
that
thing fastened above
the atm?
smickles: that's be a nifty aparatus
to set up, and no one notice it
mircea_popescu: for instance, a new way
to steal cards consists of using a laser
to measure
temperature right after owner used
the card
smickles: well maybe
that's why i'm not a comp sci phd
mircea_popescu: seems more like a (pretty strong) random number generator
than anything.
mircea_popescu: is not
too close
to
the dt' between same in
trade db, so your attack avenue doesn't really work
mircea_popescu: yea but what i mean
the dt between no bid being offered and bid popping on
the webserver
smickles: yeah, if
the
trade expires - no
trade in
the db if
the bot hasn't calcd its desired
trade yet, right?
mircea_popescu: you understand
the webserver is just relaying
the actual
trade db
tho
smickles: they could find
the ideal way
to
take advantage of
the misvaluation
smickles: that is, if
the attacker knew you were valuing incorrectly anyway
smickles: well, (just off hand) you are prolly using a modified BS or
the binomial method
to value
the options.
the side channel attack could use an assumption of what sort of hardware you have +
the amount of
time it
taks for
the bot
to do it's calc +
the method used
to calc value and deduce
the unknown values you use in valuing your options,
then
take advantage
smickles: would
that be
the amount of
time it
take for
the bot
to run
the calculation?
mircea_popescu: buys/sells well sometimes
the bot's orders expire before it notices.
smickles: if bitcoin's impact on history is it knocked
the world into using full reserve banking. i'd say net gain
teek: yeah.. i
think im gonna have
too
teek: and
there is like 20+ pages of BDT / JRO / blah blah blah crap
teek: wow i was busy
today and wasn't following anythign really
dub: fyi, betsofbitcoin is not widely
trusted, I would personally not put any significant amount with
them. In case anyone was planning
to, don't cry
to me :)
mircea_popescu: but for once
they splurged and hired kafka's daughter by mark
twain
to do
the script.
dub: like, not checking if
there were backups..
dub: what happened after
they
took over is more wtf imo
mircea_popescu: dub i still don't quite comprehend what
those people were
thinking. forex-y bitbucket ran by guy in china/taiwan. let us buy it while we reside in fresno ?
dub: he has been willing
to whore himself
to any vaguely bitcoin related retardation
to date
