``deribit`` backend
|
||||
------------------
|
||||
pretty good liquidity crypto derivatives, uses custom json rpc over ws for
|
||||
client methods, then `cryptofeed` for data streams.
|
||||
|
||||
status
|
||||
******
|
||||
- supports option charts
|
||||
- no order support yet
|
||||
|
||||
|
||||
config
|
||||
******
|
||||
In order to get order mode support your ``brokers.toml``
|
||||
needs to have something like the following:
|
||||
|
||||
.. code:: toml
|
||||
|
||||
[deribit]
|
||||
key_id = 'XXXXXXXX'
|
||||
key_secret = 'Xx_XxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXx'
|
||||
|
||||
To obtain an api id and secret you need to create an account, which can be a
|
||||
real market account over at:
|
||||
|
||||
- deribit.com (requires KYC for deposit address)
|
||||
|
||||
Or a testnet account over at:
|
||||
|
||||
- test.deribit.com
|
||||
|
||||
For testnet once the account is created here is how you deposit fake crypto to
|
||||
try it out:
|
||||
|
||||
1) Go to Wallet:
|
||||
|
||||
.. figure:: assets/0_wallet.png
|
||||
:align: center
|
||||
:target: assets/0_wallet.png
|
||||
:alt: wallet page
|
||||
|
||||
2) Then click on the elipsis menu and select deposit
|
||||
|
||||
.. figure:: assets/1_wallet_select_deposit.png
|
||||
:align: center
|
||||
:target: assets/1_wallet_select_deposit.png
|
||||
:alt: wallet deposit page
|
||||
|
||||
3) This will take you to the deposit address page
|
||||
|
||||
.. figure:: assets/2_gen_deposit_addr.png
|
||||
:align: center
|
||||
:target: assets/2_gen_deposit_addr.png
|
||||
:alt: generate deposit address page
|
||||
|
||||
4) After clicking generate you should see the address, copy it and go to the
|
||||
`coin faucet <https://test.deribit.com/dericoin/BTC/deposit>`_ and send fake
|
||||
coins to that address.
|
||||
|
||||
.. figure:: assets/3_deposit_address.png
|
||||
:align: center
|
||||
:target: assets/3_deposit_address.png
|
||||
:alt: generated address
|
||||
|
||||
5) Back in the deposit address page you should see the deposit in your history
|
||||
|
||||
.. figure:: assets/4_wallet_deposit_history.png
|
||||
:align: center
|
||||
:target: assets/4_wallet_deposit_history.png
|
||||
:alt: wallet deposit history
