Alpaca API Client in Rust

This is an unofficial SDK for the Alpaca API written in Rust. Alpaca is a trading platform for developers and app makers, and they provide various endpoints to access over http. The goal of this package is to provide the basic functionality for using the Alpaca API. This is a work in progress, and will need contributors to take this all the way.

Still a Work In Progress Recommended for Paper Accounts only.

Installation

cargo add alpaca_api_client

We use dotenvy to pull in the API keys. Add your API keys to an .env file in the root of your directory with these names.

/.env
APCA_API_KEY_ID=<pub_key>
APCA_API_SECRET_KEY=<secret_key>

Or find some other way to feed them into the environment.

Features

Currently, this package only provides the ability to interact with the Market Data and Trading APIs. The Broker API is not yet supported.

Usage

RS Docs | Examples

The Alpaca api is mostly designed to be manipulated through query parameters. There are some cases where they want a body in the request with our desired queries. In either case, this library operates by allowing users to manage their queries with a builder pattern. Essentially, the query params map to setters on the query builder. Here are a few examples.

Historical Bars

use alpaca_api_client::{market_data::stocks::HistoricalBarsQuery, TimeFrame};

let query = HistoricalBarsQuery::new(vec!["AAPL", "TSLA"], TimeFrame::OneDay)
    .start("2022-02-01") // date to start
    .end("2022-02-10") // date to end
    .feed("iex") // feed to use (iex is free, sip is premium). See Alpaca docs for more info
    .send() // this finalizes the query and send it off
    .unwrap();

dbg!(&query);

Here is the key question: Will bitcoin whales take advantage of the strength to sell as is their pattern?</p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Protection Band And What To Do Now</strong></h3>\n\n\n\n<p>It is important for investors to look ahead and not in the rearview mirror.</p>\n\n\n\n<p>Consider continuing to hold good, very long term, existing positions. Based on individual risk preference, consider a protection band consisting of cash or Treasury bills or short-term tactical trades as well as short to medium term hedges and short term hedges. This is a good way to protect yourself and participate in the upside at the same time.</p>\n\n\n\n<p>You can determine your protection bands by adding cash to hedges.&nbsp; The high band of the protection is appropriate for those who are older or conservative. The low band of the protection is appropriate for those who are younger or aggressive.&nbsp; If you do not hedge, the total cash level should be more than stated above but significantly less than cash plus hedges.</p>\n\n\n\n<p>A protection band of 0% would be very bullish and would indicate full investment with 0% in cash.&nbsp; A protection band of 100% would be very bearish and would indicate a need for aggressive protection with cash and hedges or aggressive short selling.</p>\n\n\n\n<p><strong>It is worth reminding that you cannot take advantage of new upcoming opportunities if you are not holding enough cash.&nbsp; </strong>When adjusting hedge levels, consider adjusting partial stop quantities for stock positions (non ETF); consider using wider stops on remaining quantities and also allowing more room for high beta stocks.&nbsp; High beta stocks are the ones that move more than the market.</p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Traditional 60/40 Portfolio</strong></h3>\n\n\n\n<p>Probability based risk reward adjusted for inflation does not favor long duration strategic bond allocation at this time.</p>\n\n\n\n<p>Those who want to stick to traditional 60% allocation to stocks and 40% to bonds may consider focusing on only high quality bonds and bonds of five year duration or less.&nbsp; Those willing to bring sophistication to their investing may consider using bond ETFs as tactical positions and not strategic positions at this time.</p>\n\n\n\n<p><strong>The Arora Report is known for its accurate calls.
