Poloniex™ Ninja

Poloniex™ Ninja is a Chrome extension which provides simple tools and utilities which are otherwise unavailable on the Poloniex™ website during trading and auditing.

The tools aim to improve decision making by reducing the time needed for hand calculations usually done using external tools. Please read the disclaimer below before using this software.

Features

• Extra balance columns for better stats and tracking
• Real-time ticker of current prices and holdings
• Filtering of untraded coins (e.g. to see earnings for sold out coins)
• Easy settings via Chrome toolbox or right-click context menu
• Inline donation info at withdrawal form (accepting various coins)

The extra balance columns are as follows:

• BTC Price - The last market price of the coin in BTC
• USDT Price - The last market price of the coin in USDT
• AVG Buy Price - the average weighted buy price which justifies the current balance of the coin; we consider the transaction history backwards up to the point where the net balance was 0 (including deposits and withdrawals) - this will match your trade history analysis only if you follow the same algorithm.
• EST Buy Value - the estimated buy value of the current balance (Balance * AVG Buy Price)
• Change - The growth comparing the current BTC Value against AVG Buy Value, this indicator tells you if you're currently losing or gaining money
• USD Value - Estimated value of the coin in USDT (BTC converted to USD)
• Earnings - Total earnings at last sale in BTC. Given the coin trade history (against BTC only), we compute the earnings and exclude the last consecutive purchases you made. The fees are also deducted so it's net profit or loss without the last purchases.
• Earnings USD - Same as above, converted according to current USD/BTC ratio.

Notice!

AVG Buy Price, AVG Buy Value and Change columns only consider BTC transactions against an altcoin other than USDT. This means that for example ETH and XMR exchanges for other altcoins are not taken into account (the Change column may be incorrect as well as the AVG columns).

Privacy

Poloniex™ Ninja does not collect any information about the user, prices, balances or other information or meta data associated while using the extension. All computation is done on the client, however some data may be requested using the fetch or XHR API exclusively from the Poloniex™ server (only GET requests) in order to provide more context and to be up to date.

The extension is only requesting access to [www.|api2.]poloniex.com and no other origins, hence no data is being collected and the program only operates in the browser. An additional storage permission is requested to be able to persist the user settings for the extension (Chrome sync mechanism). This does not interfere with any other Chrome extension or user data as the storage model is isolated to the target extension only.

As the extension is not collecting any analytics, your feedback is invaluable to the authors for guiding the tool towards new features, bug fixes and other improvements.

Disclaimer

This software comes with no warranty whatsoever. Any issue, damage or material loss occurred during the use of the software will not be reimbursed, repaired or otherwise acted upon by the authors. If you're using this software, you're willfully accepting the risk of a failure due to a bug, unexpected change of the Poloniex™ software or any other factor. Please review the LICENSE file for more details. The license is available at https://github.com/codesonzh/poloniex-ninja/blob/master/LICENSE .

The extension is built for research, exploratory and testing purposes without collecting any data from Poloniex™, without affecting other users and with a very low impact on the service itself (only GET requests counting well below API rate limits), please be mindful when installing extensions and make sure to review the terms and conditions of Poloniex™ before using this or other similar software.

The extension is only doing what any user with a browser and a developer console can achieve and does not use any exploits to achieve advantage as a trader. The only edge gained is less time doing side calculations using external tools and a lower probability of making a mistake given all works as intended.

The software reads available data for which the user gives permission and which the user itself can access and modifies parts of pages which are clearly visible as the extension side-effect. The extension will never try to post any data instead of the user nor prevent a user from performing an action. Modifications on the pages are only readable, non-actionable and done on the DOM level. No existing code of the website is ever getting modified or interfered with as this is built as a layer on top of the existing program (only in-memory DOM changes are applied). All computation is done in the browser tab and never leaves it's execution context (which is also achievable using the developer console).
