<h2>Current Functionality<a class="headerlink" href="#current-functionality" title="Permalink to this headline">¶</a></h2>
|
|
<ul class="simple">
|
|
<li>Backtesting and live-trading modes to run your trading algorithms, with a
|
|
seamless transition between the two.</li>
|
|
<li>Paper trading simulates order in live-trading mode.</li>
|
|
<li>Support for 3 exchanges: Bitfinex, Bittrex and Poloniex in both modes
|
|
(backtesting and live-trading). Historical data for backtesting is provided
|
|
with daily resolution for all three exchanges, and minute resolution for
|
|
Bitfinex and Poloniex. No minute-resolution data is currently available for
|
|
Bittrex. Refer to
|
|
<a class="reference external" href="https://www.enigma.co/catalyst/status">Catalyst Market Coverage</a> for
|
|
details.</li>
|
|
<li>Interface with over 90 exchanges available in live and paper trading modes.</li>
|
|
<li>Granular commission models which closely simulates each exchange fee
|
|
structure in backtesting and paper trading.</li>
|
|
<li>Standardized naming convention for all asset pairs trading on any exchange in
|
|
the form <code class="docutils literal"><span class="pre">{market_currency}_{base_currency}</span></code>. See
|
|
<a class="reference internal" href="#naming"><span>Naming Convention</span></a>.</li>
|
|
<li>Output of performance statistics based on Pandas DataFrames to integrate
|
|
nicely into the existing PyData ecosystem.</li>
|
|
<li>Support for accessing multiple exchanges per algorithm, which opens the door
|
|
to cross-exchange arbitrage opportunities.</li>
|
|
<li>Support for running multiple algorithms on the same exchange independently of
|
|
one another. Catalyst performance tracker stores just enough data to allow
|
|
algorithms to run independently while still sharing critical data through
|
|
exchanges.</li>
|
|
<li>Benchmark defaults to Bitcoin price (btc_usdt in Poloniex exchange) for the
|
|
purpose of comparing performance across trading algorithms. A custom benchmark
|
|
can be specified through <code class="docutils literal"><span class="pre">set_benchmark()</span></code> (but see
|
|
<a class="reference external" href="https://github.com/enigmampc/catalyst/issues/86">issue #86</a>).</li>
|
|
<li>Support for MacOS, Linux and Windows installations.</li>
|
|
<li>Support for Python2 and Python3.</li>
|
|
</ul>

|
|
<p>Catalyst introduces a standardized naming convention for all asset pairs
|
|
trading on any exchange in the following form:</p>
|
|
<blockquote>
|
|
<div><strong>{market_currency}_{base_currency}</strong></div></blockquote>
|
|
<p>Where {market_currency} is the asset to be traded using {base_currency} as
|
|
the reference, both written in lowercase and separated with an underscore.</p>
|
|
<p>This standardization is needed to overcome the lack of consistency in the
|
|
naming of assets across different exchanges, and making it easier to the user
|
|
to refer to the asset pairs that you want to trade.</p>
|
|
<p>Catalyst maintains a <a class="reference external" href="https://www.enigma.co/catalyst/status">Market Coverage Overview</a>
|
|
where you can check the mapping between Catalyst naming pairs and that of each
|
|
exchange. Catalyst will always expect in all its functions that you will refer to
|
|
the asset pairs by using the Catalyst naming convention.</p>
|
|
<p>If at any point, you input the wrong name for an asset pair, you will get an error
|
|

<p>In the example above, exchange Poloniex does not use USD, but uses instead the
|
|
USDT cryptocurrency asset that is issued on the Bitcoin blockchain via the Omni
|
|
Layer Protocol. Each USDT unit is backed by a U.S Dollar held in the reserves of
|
|
Tether Limited. USDT can be transferred, stored, and spent, just like bitcoins
|
|
or any other cryptocurrency. Given its 1:1 mapping to the USD, is a viable alternative.</p>
