apcacli is a command line application for interacting with the Alpaca API at alpaca.markets. It provides access to the majority of Alpaca's functionality, including but not limited to:

• inquiring account information
• changing account configuration
• retrieving account activity
• accessing the market clock
• submitting, changing, listing, and canceling orders
• listing and closing open positions
• listing and retrieving general asset information
• streaming of account and trade events

It support both the paper trading as well as the live API endpoints.

The program assumes environment variables representing the Alpaca key ID (APCA_API_KEY_ID) and secret (APCA_API_SECRET_KEY), so make sure that they are present. The program defaults to using the paper trading API. For live trading you will also need to change the URL to the API endpoint to use (APCA_API_BASE_URL).

export APCA_API_BASE_URL='https://api.alpaca.markets'; # We trade live
export APCA_API_KEY_ID='XXXXXXXXXXXXXXXXXXXX';
export APCA_API_SECRET_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';

With this setup, you can trade from the command line.

The program is powered by the apca crate and written in Rust. It comes with bash argument completion support and automatic coloring of profit/losses.

apcacli comes with Bash completion support for options and arguments to them. A completion script can be generated via the shell-complete utility program and then only needs to be sourced to make the current shell provide context-sensitive tab completion support.

$ cargo run --bin=shell-complete > apcacli.bash
$ source apcacli.bash

The generated completion script can be installed system-wide as usual and sourced through Bash initialization files, such as ~/.bashrc.
