go-kalshi

Experimental Go wrapper for Kalshi API.

This package does not expose all of the features of the Kalshi API. However, it does:

• Demonstrate how to codegen Go code from Kalshi's swagger file (available here). See Makefile.
• Show how to write higher level abstractions atop the Kalshi API
• Create a simple CLI tool kalshi-tool that performs actions like listing markets, displaying market order books, etc.

$ ./kalshi-tool --help
kalshi-tool USAGE

'kalshi-tool [--help]'
Prints this usage information.

'kalshi-tool list-markets'
The list-markets subcommand prints a list of all markets, grouped by ranged market set, with their
tickers.

'kalshi-tool market --ticker ACPI-22-C3.0'
'kalshi-tool market --ticker MOON-25'
The market subcommand takes a ticker for a single binary option and prints its Yes and No order
books.

'kalshi-tool order --action open-yes  --ticker=MOON-25 --contracts 1 --limit 0.20'
'kalshi-tool order --action close-yes --ticker=MOON-25 --contracts 1 --limit 0.50'
The order subcommand places an order for the specified ticker and amount with limit price.
Actions are:
  'open-yes' (buy yes)
  'close-yes' (buy no, with check that you have enough yes to cancel out)
  'open-no' (buy no)
  'close-no' (buy yes, with analogous portfolio check)
The first command opens a Yes position (buys Yes), assuming there is currently a No bid of
1-0.20 = 0.80 or higher. If there's not, it creates a resting order for Yes with a bid price
of 0.20. The second command closes a Yes position. First it verifies that you have a Yes position
of that size or larger, then it buys a No position in that amount with a limit price (max you'll
pay for No) of 0.50.

'kalshi-tool list-resting'
The list-resting subcommand prints a list of all resting orders and their ids.

'kalshi-tool cancel-resting --order 1250e322-c586-5ffb-bb6e-14a9503b8997'
The cancel-resting subcommand cancels an order by its id.

'kalshi-tool portfolio'
The portfolio subcommand prints your current open positions.

Instructions

Using the kalshi-tool command in this repo

This repo contains an example CLI command called kalshi-tool that uses the packages in this repo to interact with Kalshi. It performs tasks like listing available markets, displaying the order book for a chosen market, etc.

To run the tool, clone and create a .env file modeled after .env.example in the root of this repo. Then, build and run:

make
./kalshi-tool

Using go-kalshi from another repo

For an example application that depends on go-kalshi, check out fsctl/go-kalshi-usage-example. Follow the build instructions in that repo and it will pull in go-kalshi automatically.
