We would like to announce Galacticbot.com, an open source trade bot for the Stellar platform! We believe Stellar is the perfect platform to build and run a trade bot on. First of all many exchanges have a percentage based fees per transaction. The transactions costs of Stellar on the other hand are flat fee and neglectable. Second, compared to other blockchain platforms, Stellar settlements are one of the fastest and usually settle within two to five seconds. And third, Stellar is trying to be fair and inclusive. Everyone can connect to the SDEX (Stellar Decentralized Exchange) and start trading. And all in the spirit of open source technology! What’s not to love? We have developed Galacticbot.com in the same spirit. Our goal is to build an open source trade bot library that can be run on the Stellar network. A library that we can work and improve on as a community. Features An abstract bot class which you can extend to do implement your own trading logic Bots can be run both the Stellar public net as well as on the Stellar test net for testing Bots can be run in real time or as an simulation to test out bots and settings Exponential Moving Average (EMA) bot implemention which is currently being live tested (see below for links) Demo project to show a working implementation of the library and to allow you to get a bot up and running in minutes URL: https://www.galacticbot.com Live running bot: https://www.galacticbot.com/demo/ (No you are not allowed to edit the settings ?

An update of what we have been working on since the submissions closed over two weeks ago: First gains (and losses) have been realized by our live bot! 🙂 We have learned a lot and fixed a lot of small issues. We have added a new trading strategy: “CrashGuard bot”. It automatically buys into a stable coin when a crash is detected, and buys back again when the price is similar or better. Can be used as a passive bot for XLM holders on the Stellar network. (Currently under testing.) Because we did not want to reinvent the wheel, our bot is build on the public PHP stellar-api libary to interact with the Horizon API. ( https://github.com/zulucrypto/stellar-api ) This library was missing some features, so we had to add the following things for our bot. The Server class has been expanded with the following methods: getTradesForOffer - Returns all trades made for an specific offer. getTradeAggregations - Returns all past trades for an asset pair. getOrderBook - Returns the active order book for an asset pair Expanded the Account class with the following methods: getBalances - Returns all balances for the account's assets; getOffers - Returns all open offers of the account. We also added code to keep track of the minimum required XLM balance. We will contact the creator of the open source PHP stellar-api how to best integrate these new features into his library so everyone can benefit. (Not only our bot users.) Thanks!

This looks awesome!

I am passionate about trade bots and have used several.

I am curious how SDEX handles high speed trading and various specifics.

For example, if multiple buy orders are placed at the same price, are they filled in the order they were placed? Or by size or some other factor?

I imagine SDEX low liquidity makes most trading strategies fairly difficult to implement consistently?

Zaterdag

Thanks! Yes, they are filled in the order they were placed.

Currently the liquidity on the SDEX is fairly low compared to say Binance. But I am sure it is a matter of time, with Stellar X coming (including market making incentives), and new promising future native coins like KODAKCoin. And then there is IBM. There is lots of news in the pipe line.

Our current bot just retrieves data at set intervals, which is sufficient for EMA trading. A lot of API endpoints of Horizon (which is the interface to the SDEX) do also support streaming though, which allows for "real time" trading. (https://www.stellar.org/developers/horizon/reference/streaming.html) We are working on supporting this as well in the library, which would open up a lot other trading strategies.

Would you be interested in adding your bot to the strader leaderboard? Curious to see how it visualizes.

Zaterdag

Yes! We are on the brink of releasing a new version of the bot though, will look into after we get it up and running!

This looks great, I have never used a trading bot before so have no idea what to do but im going to work it out and give it a go.

what is your slack name on stellar slack? want to drop you a message.
