Improved overview of crypto balance on Poloniex™: buy price, growth rate and USD value of your bitcoin, ethereum and altcoins.
Poloniex™ Ninja provides simple features which are otherwise unavailable on the Poloniex™ website during trading and auditing.
Consider donating 0.002 BTC or more to this address:
* 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
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).
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
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

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
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).
