A
You
know
that
time
to
finality
aspect
right
now,
I'm
mostly
focused
on
D5
protocols,
so
that's
kind
of
where
my
interface
with
the
open
ocean
team
has
been
more
so
and
right.
Now
we
have
an
ecosystem
of
over
a
thousand
projects.
In
D5
alone,
we
have
over
300
projects,
so
platforms
like
open
ocean.
You
know
that
are
able
to
connect
liquidity
connect.
Different
projects
in
the
ecosystem
is
are
highly
invaluable
to
us,
and
you
know
we'll
continue
to
support
along
the
way.
C
Sure
so
I'm
the
I'm,
basically
working
on
the
so
here's
Marshall
and
I'm,
basically
working
on
the
for
stack
development
of
the
open
ocean
project.
So
most
time,
I'm
walking,
I'm
working
on
the
web
development
and
help
with
the
help
with
most
Tech
questions
from
the
communities.
So
yeah.
If
you
have
any
question
about
API
and
how
we,
how
and
how
about
our
contract
working
with
the
API,
so
you
so
you
can
just
have
questions
to
me.
Yep!
That's
it.
B
Awesome
cheers
Marshall
yeah,
we're
I
mean
here
open
ocean.
We're
really
really
excited
actually
that
we're
the
first
Dex
aggregator
to
be
integrated
or
through
the
Gateway
on
on
hummingbot.
So
from
our
end,
we're
really
big
fans
of
avalanche.
It's
it's
huge.
We
see
huge
traffic
of
it
through
our
Network,
so
we're
just
really
glad
that
you
know
we
could
launch
on
hummingbot
and
have
Avalanche
be
the
first
Network
that
we
launch
on.
B
I
guess
today,
I
think
we're
we're
here
to
talk
about
mainly
mainly
about
the
the
integration
you
know.
Avalanche
has
been
like
I
said
absolutely
huge
for
us.
The
fact
that
you
know
they
can
they
can
scale
like
they
do
the
the
subnets
as
well.
On
your,
we
see
such
a
large
volume
of
traffic
go
through
our
platform
in
terms
of
in
terms
of
like
game
fight,
so
it
counts
for
a
significant
portion
of
our
traffic.
A
Think
the
the
theme
of
self-custody
and
going
on
chain
and
using
dexes
to
you
know
do
what
they
need
to
do
right
by
whether
it's
buying
trading
selling
tokens
I
think
that
narrative
is
gonna.
You
know
carry
on
and
that
you
know
within
Avalanche
alone.
I
think
we
have
like
I,
don't
even
know
how
many
Integrations
you
guys
have
guy,
but
at
least
a
dozen
dexes
right
there
are
like
pretty
heavily
used
and
open
ocean
I.
A
B
Yeah,
no
just
just
attack
on
the
back
of
that
yeah.
We
do
more
than
15
decks
on
on
Avalanche,
so
yeah,
it's
a
it's
a
huge
Focus
for
us
and
it's
you
know
it's
like
personally,
it's
one
of
my
favorite
chains
and
I
love
the
ability
at
which
you
can
you
can
scale
as
well,
so
yeah
super
excited
to
be
to
be
here
on
on
Avalanche
and
and
talking
about
open
ocean
today.
D
B
A
B
I
think
I
think
we
can
start.
We
can
start
looking
at
it,
I
mean
I've,
I've
only
been
getting
to
grips
with
hummingbot,
for
maybe
the
past,
like
three
or
four
days,
I
mean
I've,
I've
used
other
other
tools
and
stuff
in
the
past.
So
because
I
come
from
a
like
a
community
business
development
background,
I've
had
to
teach
myself
how
to
how
to
set
it
up
and
get
it
running
so
I've
got
the
I've
got
my
you
know.
My
disk
drive
Ubuntu
running
and
I
had
this
set
up
over
the
weekend.
B
Some
very
nice
help
from
from
some
of
the
staff
in
in
the
Discord,
and
it's
really
kind
of
a
breath
of
fresh
air,
like
the
the
whole
whole
GUI,
the
way
everything's
laid
out.
You
know,
once
you
got
up
and
running
it's,
it's
really
easy
to
use.
I
find
and
I
was
able
to
set
up,
I
mean
not
talking
specifically
about
the
parameters,
but
I
was
able
to
set
up
a
campaign
like
really
quickly
and
I.
Think
for
anyone
who's
sort
of
wanting
to
get
into
this.
B
Having
something
up
and
running
that
they
can.
You
know
look
at
and
and
see
working
regardless
of
of
whether
or
not
it's
you
know
extremely
profitable
or
not,
but
just
as
a
test
and
I
think
the
the
way
that
the
hummingbot
allows
people
to
do
that,
along
with
all
the
docs
and
everything
is
really
easy,
because
you
know
like
a
need
for
myself.
I
was
able
to
set
something
up
and
I
actually
have
it
running
in
a
relatively
short
amount
of
time.
E
E
The
integration
or
the
installation
of
honey,
but
it
was
very
easy
for
you.
One
thing
that
that
I
would
ask
is
that?
Can
you
or
maybe
it's
a
good
thing
for
the
community
and
you
create
some
kind
of
a
YouTube
video
or
something
like
that?
I,
don't
know
if
you
have
a
channel
in
avalanche
our
labs
to
to
to
upload
some
video,
how
to
use
hammibot
with
that
connector
I
think
that
that
that
kind
of
stuff
is
very
useful
for
for
the
community,
because
mostly
they
are
familiar
with
Sexes.
E
Well,
these
kind
of
things
are
helpful
for
them.
So
that's
the
only
comment
that
I
have
for
my
side
and
I
would
like
to
read
the
the
comments
that
the
community
mentioned
here.
We
have
one
from
Memento
that
is
asking:
how
would
a
integration
work?
Does
open
ocean
provide
order,
books
or
provide
connection
to
other
decks?
That's
one
of
the
connection
of
the
questions
for
you
guys.
D
B
So
I
mean
we
are
on
on
Avalanche.
We
aggregate
I
think
in
a
total
of
like
18
other
exchanges,
and
we
use
you
know
a
hybrid
pricing
model,
but
everything
from
the
sushi
swap
to
kyber
swap
to
R.
But
you
know,
all
of
that
is
is,
is
on
our
books
to
pull
liquidity
from
so
and
no
matter.
If
say,
like
the
trade
that
you
want
to
make.
So
you
want
to
make
a
really
large
trade
you
want
to
buy
I,
don't
know
a
10
each
trade.
B
If
our
algorithm
can
detect
that
that
trade
actually
works
out
cheaper
for
you
broken
down
into
three
four
five,
smaller
trades,
then
what
it
will
do
is
actually
we'll
break
that
trade
down
and
push
it
through.
But
ultimately,
at
the
end
of
the
day,
what
we're
looking
for
is
is
gas
savings.
You
know
we're
trying
to
save
the
most
amount
of
of
gas
possible
and
so,
whether
that's
doing
it
in
in
one
trade
or
over
five-
and
you
know
that
we-
we
even
split
that
amongst
different
protocols
as
well.
B
B
So
if
you
know,
because
that's
the
problem
with
a
lot
of
a
lot
of
decks
is
if
you're
just
going
on
the
decks
is
the
liquidity
is
siled,
so
I
mean
the
liquidity
is
specific
to
that
Dex.
But
what
you
get
by
sort
of
pulling
all
of
them
together
is
the
ability
to
trade
with
really
low
slippage
rates,
and
you
know
the
pole
for
price
is
a
lot
quicker
because
of
the
you
know
the
amount
of
liquidity.
That's
there
to
trade
between.
E
E
Okay,
that's
very
cool
so
and
based
on
the
the
question
of
memento
that
he
says
primarily
works
with
the
other
books.
This
will
be
more
like
an
a
trading
we.
It
will
be
more
trading
with
LPS
right.
Yes,
because
we
have
another.
We
have
another
dexis
like,
for
example,
serum
well
now
now
Serum
is
down
to
but
dydx
that
has
order
book
and
is
decentralized
and
in
this
case,
will
be
more
like
this
will
be
trading
against
liquidity,
pools.
E
Okay,
perfect
Memento
that
solves
your
well.
There
is
another
question,
so
if
my
window
has
another
question,
I
will
read
later
but
to
say
your
ex
says
this
pulling
on
low
zippatch
and
fee
efficiencies
are
what
a
one-inch
has
been
doing
for
a
long
time
now
or
does
open
ocean
have
some
even
better
optimizations.
B
E
B
Yeah
yeah,
no,
that's
that's
fair
enough.
I
was
actually
just
seeing
if
I
could
share
my
screen,
so
I
could
show
people
what
I'm
talking
about
as
we're
walking
through
this,
but
I
can't
seem
to
find
it
so
I'm
just
gonna
talk
about
it
in
general,
okay,
yeah!
So
that's.
That
is
a
question
that
we
get
asked
a
lot
which
is
you
know
why
should
I
use
your
platform
over
one
inch
over?
You
know
there
are
a
lot
of
other
competitors
and
I
think
mainly
this.
B
This
breaks
down
into
the
routing
algorithms
that
are
used
so
on
various
on,
say,
like
on
specific
trades
on
a
lot
of
Trades
that
you
put
in
you'll,
get
a
very
similar
Chrysler
price
across
a
lot
of
Dex
aggregators,
but
with
with
open
ocean.
What
we
actually
do
is
because
we
have
such
a
wide
variety
of
Integrations
and
the
tools
that
we
introduced
to
trade
with
we,
we
sort
of
believe
that
that
makes
a
better
trading
experience.
B
B
It
tells
me
who
I'm
going
to
be
routing
the
transaction
through,
and
it
also
tells
me
the
comparison
so
I'm,
just
I
literally
just
put
in
that
trade
right
now
and
I
can
see
that
I'm
cheaper
than
quite
a
lot
of
other
dexes
on
on
on
Avalanche,
but
also
that
I'm
I'm
running
more
or
less
about
exactly
the
same
as
as
one
inch.
But
what
we
do
you
know
more
than
other
Dex
aggregators
is
offer
very
lucrative
gas
referral
and
rebate
scheme,
so
I
mean
if
you're
really
into
the
platform.
B
B
What
like,
if
you
do
it
through
us,
you
have
the
ability
to
earn
the
reduction
in
those
gas
fees
as
well,
as
you
know,
have
access
to
the
selection
of
chains
and
dexes
that
we're
on
because
that's
what
we
like
to
say
is
that
yeah
open
engine
is
the
widest
Dex
aggregator
in
terms
of
the
the
web
of
where
we
can
reach
but
yeah.
There's.
There's
we
like
to
you
know
especially
give
a
shout
out
to
to
our
epic
Community
team.
B
They
do
a
really
good
job
in
keeping
the
community
engaged
and
we're
we're
very
thankful
that
you
know
we've
got
such
a
good
community
on
us,
so
it
much
like
coming,
but
you
know
if
you
ever
need
help.
If
you
ever
need
support,
we've
always
got
people
on
hand
to
help
you
and
things
like
that,
and
you
know
that's
not
just
for
retail.
That's
also
for
you
know
if
you're
working
with
our
API
or
SDK
kit,
that
that
extends
to
that
as
well.
E
Oh
okay,
perfect
there
is
a
Mike
says
if
you
have
like
a
link
or
a
picture
to
share
in
the
there's
a
chat
that
is
like
up
just
before
a
proposal.
Discussion
to
this
community
called
chat
and
where
the
people
is
asking
questions.
If
you
can
share
like
yeah
a
couple
screenshots
in
there,
yeah
yeah,
because
we
we're
in
DC
scored
chat
or
a
conversation,
does
doesn't
have
the
ability
to
share
screen
so
P
eight
create
Ask.
How
would
the
connection
with
hummingbot
work
through?
E
B
E
B
We
so
we
we
have
with
the
with
the
limit
orders.
We
we
use
something,
you
know
a
request
for
quote
price
and
we
people
can
make
and
cancel
as
many
limit
orders
as
they
want
with
you
know,
without
incurring
any
extra
fees
and
limit
orders
was
something
that
we
wanted
to
to
introduce,
so
people
could
feel
confident.
You
know
stepping
away
from
that
centralized
exchange,
but
also
still
achieving
you
know
getting
being
able
to
catch
the
dips
or
being
able
to
sell
at
a
specific
price.
B
E
E
B
I
would
well
I
would
say
that
you
know
our
our
routing
algorithm
is:
is
novel
and
unique
a
lot
of
unlike
a
lot
of
other
platforms
and
actually
like,
even
though
they
use
their
cheer
token,
you
know
we're
able
to
achieve
a
comparable,
if
not
better,
results
on
on
certain
trades.
I,
don't
know
if,
if
Marshall
you
and
to
jump
a
little
bit
more
into
the
optimization
of
that
or
not
or
you
just
wanted
to
add
anything
on
top.
B
I
think
we
know
we're
talking
about
the
so
one
of
the
users
has
asked
us,
so
one
inch
uses
the
cheer
token
to
optimize
trading
fees
and
I
was
saying
that
we,
you
know,
we
use
our
novel
routing
algorithm,
but
I
just
thought.
Maybe
you
could
touch
on
you
know,
maybe
something
like
in
in
detail
from
from
our
Dev
team
side
that
we
do
to
to
Really
keep
those
fees
down.
D
C
Middle
holder
and
the
open
ocean
gonna
cover
about
that
and
for
this
for
the
zero
gas
fee
and
there's
a
another
part
about
about
optimizing.
The
Gap,
the
gas
cost
just
more
about
the
used
Instagram
page
to
cover
the
to
cover
the
to
cover
the
gas
fee.
So
there's
another
way
for
us
to
to
optimizing
the
the
gas
cost
as
well.
C
D
B
It's
the
the
traffic,
especially
recently
since
you
know,
Market
turmo,
has
has
been
absolutely
mad
and
I
think
it's
especially
on
the
11th.
You
know
we
saw
unprecedented
levels
of
of
swaps
and
stable
swaps
on
the
platform,
so
I
was
I'm
just
just
reading.
Another
comment
says
wanted
to
know:
we
looked
at
one
inch
in
details
for
our
own
competitive
Advantage.
Yeah.
Absolutely-
and
you
know
one
one
part
of
staying
ahead
of
the
game
is
also
you
know
they
say,
keep
your
friends
close,
but
your
competitors
closer.
B
E
C
There
was
another
one
that
might
add
up
something
like
that
yeah
sure
so,
I
think
our
like
most
of
our
contract
is
opened
for
on
the
for
the
community,
and
we
we
have
part
of
the
project
which
is
like
the
call
like
the
coke
hold,
which
is
not
opened
yet,
but
most
of
like
our
API
and
and
the
front
end
code.
They
are
opened
and
you
can
just
go
to
the
GitHub
and
check
them
on
the
website.
E
E
D
E
E
B
Yeah,
that's
definitely
something
that
will
feed
back
to
the
team,
and
you
know
this
is
another.
Like
I
said
this
I'm
just
gonna
add
this
is
another
strength
of
you
know.
The
fantastic
team
that
we
have
is
that
with
Integrations
and
new
Partnerships,
especially
like
this
is
we
can,
you
know,
work
with
the
teams
and
and
customize
everything
to
your
liking.
So
one
of
the
great
benefits
of
having
a
flexible
Dev
team.
B
E
B
E
B
From
from
the
connector
from
open
ocean,
I
would
just
say,
yeah
make
sure
you're
following
us
on
on
Twitter,
give
the
give
the
connector
a
try
jump
into
the
Discord,
and
you
know
share
your
experience
with
us,
because
it's
always
interesting
to
hear
people's.
You
know
how
they
use
our
platform
and
and
how
they're
going
to
use
it
with
hummingbot
yeah.
That's
then
I
think
I
think
that's
what
I'll
add
Eric.
E
D
D
B
E
E
Well,
perfect:
well,
thank
you
very
much
to
share
this
with
us.
Well,
the
only
thing
that
I
I
think
that
the
community
will
like
and
will
be
easier
for,
the
the
people
that
is
trying
to
get
started
trading
on
dexis.
You
see,
if
you
can
I,
don't
know,
create
a
YouTube
video
to
and
upload
it
to
to
your
Channel
or
something
like
that
or
or
we
can
talk
with
Carlito,
to
make
something
like
that.
That
would
be
very
good
and
we'll
help
other
people
to
get
started
with
your
connector
so
well,.
E
F
Me
introduce
myself
I'm
left
there,
I've
been
around
hummingbot
for
around
three
years.
Do
mostly
liquidity
campaigns
and
I
rely
on
data
analysis
heavily
to
be
profitable
when
I
am
developing
my
trading
strategies
and
recently
I
prepared
a
little
little
competition.
Some
data
science,
nice
back
testing
competition
or
the
hummingbot
community
I,
will
send
a
GitHub
link
to
the
description
and
some
Source
codes
to.
F
A
minute
so
I
prepared
no
example,
notebook
example,
competition
entry
and
the
notebook
contains
a
back
test
of
the
hummingbot
pure
Market,
making
strategy.
That's
something
similar
to
what
I
trade
the
vectors
is
very
simplified
at
the
moment.
It's
just
just
around
20
lines
of
code,
so
so
you
can
as
a
competition
entry.
F
You
can
extend
this
back
test
or
commit
some
some
new
notebook,
exploring
anything
interesting
around
hummingbot
strategies
or
cryptocurrency
Trading
I
shared
some
of
the
market
data
I
collect
for
for
those
analysis
that
you
can
use
and
I
have
two
goals
for
the
competition.
I
would
like
to
support
this
data-driven
approach
to
Trading,
because
I
believe
this
is
the
straightest
way
to
to
be
profitable
in
the
long
run
and
to
avoid
some
risks,
some
daily
risks
of
Market
making
volatility
and
Etc,
so
I
think
data
driven
approaches
really
really
good
way
and
honestly.
F
F
So
the
main
price
for
the
winner
is
full
access
to
all
those
Market
data,
two
or
three
years
of
data
order,
books,
rights,
stuff
like
that
plus
you
learn
something
new
and
get
feedback
on
your
crypto
research.
I
worked
as
head
of
research
in
equity,
Trading,
Company,
so
I
hope
my
feedback
will
be
valuable
and
yeah.
That's
that's
it
probably
I.
Welcome
you
to
join.
E
F
F
E
Questions
sorry,
one
of
the
questions
that
I
had
was
like
I
saw
that
you
were
like
calculating
the
the
beat
and
ask
prices
from
pandas
data
frame
that
has
all
that
information.
But
in
that
case,
are
you
using
the
the
the
order
refresh
time?
That's
one
of
the
questions
that
I
that
I
had
for
debug
testing.
F
B
E
Yeah
that
that's
one
of
the
one
of
the
things
that
I
saw
but
I
think
that
is
a
very
good
approach,
because
to
start
it
will
be,
will
be
enough
this
and
then
we
can.
We
can
I
think
that
we
can
improve
it,
but
and
also
the
for
Loop.
We
consume
probably
a
lot
of
resources
depending
on
the
quantity
of
information
that
you
have,
but
I
I
like
I,
like
the
notebook,
a
lot
I
review.
E
F
F
E
D
E
That's
awesome.
That's
awesome,
I,
think
that
besides
the
competition
and
all
this
is
a
very
huge
contribution
to
the
community
to
start
building
more
reliable
Bots,
they
can
start
building
some
strategies
that
they
can
back
test
and
be
be
confident
of
what
they
are.
They
are
using
so
very,
very
good
job
lifting,
and
thank
you
very
much
to
share
this
with
the
with
the
community
so
well
yeah.
Do
you
want
to
share
anything
else?
Besides
that.
F
E
E
Thank
you
very
much
for
this
contribution
and,
if
you,
if
there
is
anyone
that
has
other
questions
we
can,
we
can
answer
that.
Probably
I
don't
know,
but
I
don't
know,
which
is
the
the
timeline
for
this
competition,
but
we
can
make
like
an
temporary
group
or
temporary
channel
for
this
I.
Don't
know
what
do
you
think
Carlito
or
share
me
or
Mike,
but
probably
we
can
make
a
a
channel
to
discuss
the
all
this
topic
for
a
while
or
we
can
use
I.
E
E
E
E
So
there
is
the
the
link
for
the
The
Proposal
of
the
mini
lessons
for
the
next
weeks.
This
idea
is
to
the
idea
of
this
is
to
create
more
content.
That
is
related
with
the
things
that
you
want
to
learn.
Last
communico,
we
made
a
boat
in
here
and
those
were
the
topics
that
the
people,
the
media,
is
more
interested
in
so
well.
Today
we
have
the
the
community
talk
with
open
ocean
on
the
competition
of
Lefty.
E
Next
week
we
are
going
to
have
an
overview
of
a
perpetuous
connector,
which
are
the
things
that
the
operators
connector
is
managing
and
all
that
stuff.
Then
we're
going
to
review
the
post
Pro
the
next
week
the
pros
post
process
tool.
This
is
a
tool
that
was
built
by
James,
P,
Magic,
I,
think
that
is
useful
to
analyze
your
traits.
E
E
So
probably
we're
going
to
share
a
script
where,
where
we
are
using
a
central
exchange
and
a
centralized
exchange
at
the
same
time,
then
the
other
one
is
the
monthly
Community
call
remember
that
all
the
the
second,
the
second
Wednesday
of
all
the
month,
the
second
Wednesday
we
all
we
always
have
the
monthly
Community
call.
So
that's
what
why
we
have
it
there.
E
Then
we
have
the
the
next
one
will
be
the
docker
composed
to
run
multiple
Bots
I
already
created
a
video
of
that,
but
well
now
the
the
the
the
code
changed
a
little
bit.
So
the
the
follow
structure,
the
follow
structure
is
a
little
bit
different
and
some
of
you
have
some
questions
about
it.
So
I
can
explain
a
little
bit
about
how
to
use
server
compose
then
the
the
next
week
we're
going
to
have
the
feature
of
price
Source,
all
the
the
the
the
first
all
the
topics.
E
We
are
going
to
to
explain
all
the
topics,
but
we
also
are
interested
in
some
Community
developers.
That
wants
to
explain
this,
for
us
like,
for
example,
left
T
to
data
shares,
Keys
knowledge
or
his
thoughts
about
back
testing
or
anyone
that
wants
to
share
something.
So
if
you
want
to
explain
one
of
these
topics,
just
reach
us
reach
out
on
Discord
and-
and
we
can
coordinate
that-
but
well
this.
These
are
good
topics.
E
For
that,
too,
then,
we're
going
to
have
the
spot
connectors
like
like
the
explanation
of
the
Perpetual
connector,
but
for
spot
connectors,
which
are
the
things
that
spot
connectors
are
managing
the
next
one
is
also
a
monthly
Community
call
and
then
we're
going
to
have
the
last
two
weeks
of
January
an
explanation
of
the
rate
Oracle
that
I
asked
Memento.
If
he
wants
to
to
share
this
with
us,
because
he
already
built
the
rhetorical
of
gate
IO.
But
he
says
that
he's
a
little
bit
shy
to
speak.
E
So
I
don't
know,
I
have
to
convince
him,
maybe
with
some
Xbox
and
and
the
last
thing
that
we
have
is
explanation
of
the
stringy
tabs
that
I
built
so
probably
we're
going
to
make
some
some
demonstration
of
how
to
create
a
new
page
and
add
some
custom
analysis
to
that
page,
create
a
PR
and
all
that
stuff.
So
well,
that's
the
proposals.
E
We
have
a
schedule
for
November,
December
and
January,
so
we
have
like
almost
three
months
covered
with
this
schedule
and
if
you
are
interested
in
other
topics,
so
there
is
no
comment
on
the
on
the
channels.
There
is
a
proposals
of
mini
lessons
that
Carlito
created
under
the
developers
section
on
Discord.
So
if
you
want
to
learn
about
a
specific
topic
create
a
thread
there,
we
are
going
to
review
it
and
probably
add
it
to
the
next
the
next
sessions
that
we
have
so
well.
That's
all
Community
for
this
week.
