 [exchange/indodax]
 api_key    = S6WBYR6Q-TVMTSFOA-YWK6GSNT-H0JMEK6Z-YDF5ML9Y
 api_secret = e16064aa7fb477b267fe774df62194f33583c7f46a09ad931ca2e097aeaa9c9296e1c3b2734bab71

 ; if you have another account on the same exchange
 [exchange/indodax/wifey]
 api_key    = EKSGJUOR-ROR9K24P-Q45UBWVG-GZHANPQV-UY4Z1WBM
 api_secret = 71100dc13ffe4d082239c06b5c36fd8f0548cd97056ffa2ee491ae4dfd4f996fb468ef3c70b12073

DESCRIPTION

Early release. More functionality will be added in the future.

cryp-exchange is a multi-cryptoexchange CLI. This distribution provides common interface (as CLI as well as driver modules) to interact with different cryptocurrency exchanges including:

  • common set of subcommands (API methods)

    Along with common terminology, arguments, error behavior, and result format.

  • standardized currency codes and pair formats

    Following CryptoCurrency::Catalog.

SUBCOMMANDS

accounts

List exchange accounts.

balance

List account balance.

cancel-order

Cancel an order.

create-limit-order

Create a limit order.

exchanges

List supported exchanges.

get-order

Get information about an order.

open-orders

List open orders.

orderbook

Get order book on an exchange.

pairs

List pairs supported by exchange.

ticker

OPTIONS

* marks required options.

Common options

--config-path=filename

Set path to configuration file.

Can be specified multiple times.

--config-profile=s

Set configuration profile to use.

--debug

Shortcut for --log-level=debug.

--format=s

Choose output format, e.g. json, text.

Default value:

 undef
--help, -h, -?

Display help message and exit.

--json

Set output format to json.

--log-level=s

Set log level.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:

    [1,2,3]
--no-config

Do not use any configuration file.

--no-env

Do not read environment for default options.

--quiet

Shortcut for --log-level=error.

--subcommands

List available subcommands.

--trace

Shortcut for --log-level=trace.

--verbose

Shortcut for --log-level=info.

--version, -v

Display program's version and exit.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

 complete -C cryp-exchange cryp-exchange

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

 complete cryp-exchange 'p/*/`cryp-exchange`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

CONFIGURATION FILE

This script can read configuration files. Configuration files are in the format of IOD, which is basically INI with some extra features.

By default, these names are searched for configuration filenames (can be changed using --config-path): ~/.config/cryp.conf, ~/.config/cryp-exchange.conf, ~/cryp.conf, ~/cryp-exchange.conf, /etc/cryp.conf, or /etc/cryp-exchange.conf.

All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

To put configuration for a certain subcommand only, use a section name like [subcommand=NAME] or [SOMESECTION subcommand=NAME].

You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SOMESECTION profile=SOMENAME] or [subcommand=SUBCOMMAND_NAME profile=SOMENAME] or [SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

You can also put configuration for multiple programs inside a single file, and use filter program=NAME in section names, e.g. [program=NAME ...] or [SOMESECTION program=NAME]. The section will then only be used when the reading program matches.

Finally, you can filter a section by environment variable using the filter env=CONDITION in section names. For example if you only want a section to be read if a certain environment variable is true: [env=SOMEVAR ...] or [SOMESECTION env=SOMEVAR ...]. If you only want a section to be read when the value of an environment variable has value equals something: [env=HOSTNAME=blink ...] or [SOMESECTION env=HOSTNAME=blink ...]. If you only want a section to be read when the value of an environment variable does not equal something: [env=HOSTNAME!=blink ...] or [SOMESECTION env=HOSTNAME!=blink ...]. If you only want a section to be read when an environment variable contains something: [env=HOSTNAME*=server ...] or [SOMESECTION env=HOSTNAME*=server ...]. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.
