#31-10-2014 NuBot development, update #7

This week we have been working on finalising and testing the 0.1.3 release. The Release Candidate build is currently just four issues away to be approved. We aim to make the release it before or during the weekend.

###Updates

Fixed a critical bug that caused the block to get stuck when the connection with one or more pricefeeds failed.
Fixed a critical bug that caused CCEDK nonce parameter failing every now and then, causing some ugly malfunctioning.
Moved logs assets outside the logging directory to improve separation of concerns.
Fixed some bugs that was causing troubles with locale settings different from english.
Fixed several small faults that emerged during QA.
With more users, more lines of code, more features and more developers coming, we needed some change. For this reason, at project development level, we are working hard to introduce some rigorous processes. We started by switching to git flow, a structured model to develop software which fits our needs: traceability, distributed team, QA PR, mission critical software and issue-tracker driven.
We are making the first steps towards fully-automated tests : systematic tests with the support of checklists and tables.

The bot have seen an overall increased stability and reliability.

#09-11-2014 NuBot development, update #8

During the past week we released NuBot v0.1.3, and shortly after we performed a hotfix of a rounding issue that led to a minor v0.1.3a release. All custodians should have the update.

###Updates

Despite previous updates, the current version of NuBot is not (yet) ready for supporting multiple custodians on the same market. Some scenarios emerged during testing that will require a few updates to the bot to declare it risk-free for multiple custodians. Stay tuned.
Started working on release 0.1.4 which contains some major improvements.
Happily moved to a full gitflow as development workflow.
Added support for AllCoin (now testing)
Added support for BitSpark (now testing)
Set up a dedicated SMTP server for stable and reliable email notifications.
Implemented a mechanism that prevents orders to be placed at low price. It does that by using a moving average of 30 datapoints, after verifying reliability of a single price feed.
Several minor and major bug fixing and features are in progress. Please check out the public repository and its commits if you are interested in details.
Picked up tradingbot.nu for future use as official website. For the time being it simply redirect to the bitbucket repository.

#18-11-2014 NuBot development, update #9

This week we worked on v0.1.4 which we hope we can release at the end of this week after thorough testing.

###Updates

Ben and Sam are completing a Docker container ready to ship for NuBot development and execution.
Sam implemented and tested a system that will help preventing the bot to place orders at low price. The solution is almost ready to be merged into develop branch.
BitSpark wrappers tested [ok]
AllCoin wrappers tested [ok]
Improved HipChat notifications
We now use our internal SMTP server for mail notification to custodians.
Cancel all orders after price failing to update

###Bug fixes

Solved problems while parsing (some) Peatio dates.
TX fee taken into account when computing prices at the first execution
Fixed an issue that made the bot look frozen on start under particular circumstances .

NTP Client makes the bots sync.
Reset or cancel all orders after price failing to update
When computing the initial USD price, take the TX fee into account
Computed wait_time on wall shifts
Changed the API error-handling system
Refactored PriceFeedManager
Reduce damount of compulsory option parameters by introducing conditions
The bot now uses a dedicated SMTP server to send email notifications
Removed debug messages from bterwrapper
Removed printing warnings for non-global TX fee

Avoid printing buy prices if SELL side only

Bug fixes:

Bot doesn’t stop when connection lost with Peatio.
Solved a problm that led to wrong pricing with a sell-side and a dual-side custodian working on the same market/pair.
Solved Peatio wrapper problems while parsing some date
Part of the balance was not placed on (buy) order

Next version 0.1.5, is already being developed and probably one week away from QA. Stay tuned.

#09-01-2015 NuBot development, update #12

NuBot 0.1.4a has been released after 3 release candidates. It contains three hotfixes. Custodians are invited to update (no need to review the configuration file.).

Next version (0.1.5) contains some major improvements and upgrades that will be detailed here before release, a couple of weeks from now.

#16-02-2015 NuBot development, update #15

After 9 release candidates today we released NuBot v0.1.5

Download at https://bitbucket.org/JordanLeePeershares/nubottrading/downloads/nubot-v0.1.5.zip

All custodians are invited to upgrade to new version and follow the new setup tutorial. The old JSON configuration files (0.1.4) will not work.

Beside containing multiple updates, features, refactoring and bug fixes, the most important feature is a temporary way for more than one custodian to co-exist on the same non-USD pair.

Multi-custodian mode will sync with remote NTP and reset orders every three minutes, regardless of the peg price. This mode can be activated by changing this setting :

"multiple-custodians":true

Please set it to false if you are sure that no other custodian’s bot are active on the same pair, as it will be more efficient.

It has been tested thourougly with good results an no wall collisions. However a wall collision can happen in case one bot stop functioning and leaves the orders up (connection interrupted, machine crash … ) . This is inevitable, but for all other cases I still have 600NBT that are allocated to reimburse TX fees paid on collision.

Full changelog : please read carefully

#09-05-2015 NuBot development, update #19

After 4 release candidates today we released NuBot v0.3.0

It started as a minor release to provide a graphical interface to setup the bot. It ended up being a bold major release with almost 800 commits in three weeks.

NuBot As A Service : WebGUI

Custodians have now the option of running NuBot as a service and access a web dashboard to configure,run and monitor the bot’s execution.

This upgrade required a deep refactoring and codebase improvement (see full changelog) and the implications are far from being aesthetics-only : now NuBot can now be run on a remote VPS and be controlled from a smartphone (to name one possibility).

I put together a small screencast demonstration.

The GUI is in alpha/MVP version with a minimal set of funcionalities, please forgive us for the low attention to UX : we focused in making client-server interaction as solid and extensible as possible. Future versions will contain a proper fully operation dashboard and much more.

#11-06-2015 NuBot development, update #20

After 7 release candidates today we released NuBot v0.3.1

Pushing price updates through websockets

NuBot can connect to a streaming server (if available) using a websocket and listen and react to commands received from the Server. In this scenario we have two actors : the server (Streamer) and the clients (Subscriber).

This feature has been long awaited, as it now allows multiple custodians to consume a reliable pricefeed and subscribe to push updates. Wall-shifts will now happen simultaneously across exchanges and custodians. Risks derived from wall collisions are significantly reduced (to near 0).

The push service architecture we implemented is robust and each client autonomously performs sanity checks on the price received before acting. It allows hot-swaps of server machines and a load balancer drives the traffic in the right direction. The Streamer tracks the price of multiple fiat and crypto-currencies, and also suggest a price offset to clients (now statically, in the future dynamically).

The full documentation of this service is available on bitbucket.

Sources and docs at http://tradingbot.nu

Notes for custodians :

All custodians are invited to upgrade to the new version. Please follow and carefully read the new setup tutorial. The old JSON configuration files will not work.

Introduced default configuration parameters. We suggest leaving most options as default.
Deleted configuration parameter : verbose (boolean)
Added configuration parameter : verbosity (string)
Added configuration parameter : bypassStreaming (boolean)
Added configuration parameter : streamingServer (string)
Removed configuration parameter : hipchat (boolean)
Added configuration parameter : gitter (boolean)
Added configuration parameter : webport (int)

Changed default web port from 4567 to 8889.

Apply for a credential token : since the bot uses external services that require authentication, you’ll need to apply for a valid auth-token file that is not distributed with the bundle for obvious reasons.
If you are applying as custodian, use this form to request a valid key. You can also skip this step if you plan to manually configure tokens/keys.

Launch string changed to accomodate new optional CLI flag -skipCredentials.
GUI flag renamed to -sever

java -jar NuBot.jar -cfg=<path/to/config.json> [-server] [-skipCredentials]

Please read carefully

v0.3.1 Changelog

New Features:

Price-feed streaming service implementation and deployment. Details are documented here)

Uncountable minor and major fixes.

For the upcoming 0.3.2 version, we are shifting our focus away from priceservice and going to integrate parametric order books into the trading strategy. Stay tuned for next announcement.

desrever · October 8, 2015, 12:16am

#08-10-2015 NuBot development, update #21

After 9 release candidates today we release NuBot v0.3.2 . It packs a bunch of improvements, bug fixes, new wrappers and features. Among changes the most import is the introduction of parametric order books.

Parametric orderbooks

Up until NuBot v0.3.1, all the available liquidity was put up on a large single order, according to the initial design outlined in the whitepaper. Starting from NuBot v0.3.2 and following the evolution of liquidity operation the bot implements the multi-tier liquidity model.

In this model, NuBot places the vertical walls at the best price (Tier1) along with a tail of orders distributed at premium prices and controlled by bot operators: the parametric order book.

By managing liquidity this way operators can mitigate risks of being exposed to volatility and malicious actors while still providing a solid 1$ peg.

The model is simple and at the same time flexible enough for making it fit in different market scenarios.

The model can be configured by the custodian using the configuration file or directly in the UI.
The model is dynamic, in the sense that its parameters can be manipulated at runtime.
NuBot will implement capabilities to autonomously adapt parameters to best fit market conditions.
The buy and sell liquidity can be modelled separately
If you launch NuBot with the GUI, you will be able to change parameters and see a real time preview of how changing parameters affects the shape of your orderbook.
Once the bot detects that most of tier1 liquidity has been consumed, it will replenish it. (in following version this dynamic will undertake radical changes , with market-aware orderbooks)

Demo

#19-11-2015 NuBot development, update #22

NuBot 0.3.2a has been released and contains just a simple hotfix that corrects a bug in pricing that only affected sell-side mode.

Upgrade recommended for current 0.3.2 bot users : no need to change anything in your config, replacing NuBot.jar is enough .

#09-03-2016 NuBot development, update #22

After 2 release candidates today we release NuBot v0.4.1 . It packs a bunch of improvements, bug fixes, new wrappers and features. Among changes the most import is the introduction of communication with Automated Liquidity Provision servers (ALP v2) .

Activate it via config parameters of UI

 "poolMode" : false,
 "poolURI" : "",
 "poolPayoutAddress" : "xxx",
 "poolSubmitInterval" : 60

It also comes with some UI revamp and functionalities .

The orderbook design preview is now available right in the webpage, with no need to refresh the page or install java. This is good news for raspberry pi users, and in general users that want to install NuBot as a remote service.

Improved the configuration and dashboard page, using bootstrap responsive layouts and components. This should be an attractive point for this release, since we aim to attract as many providers as possible.
