<p>This page explains how to tune your strategy by finding the optimal
parameters, a process called hyperparameter optimization. The bot uses several
algorithms included in the <code>scikit-optimize</code> package to accomplish this. The
search will burn all your CPU cores, make your laptop sound like a fighter jet
and still take a long time.</p>
<p>Hyperopt requires historic data to be available, just as backtesting does.
To learn how to get data for the pairs and exchange you're interrested in, head over to the <a href="../data-download/">Data Downloading</a> section of the documentation.</p>
<div class="admonition bug">
<p class="admonition-title">Bug</p>

<p>Before we start digging into Hyperopt, we recommend you to take a look at
the sample hyperopt file located in <a href="https://github.com/freqtrade/freqtrade/blob/develop/freqtrade/templates/sample_hyperopt.py">user_data/hyperopts/</a>.</p>
<p>Configuring hyperopt is similar to writing your own strategy, and many tasks will be similar and a lot of code can be copied across from the strategy.</p>
<p>The simplest way to get started is to use <code>freqtrade new-hyperopt --hyperopt AwesomeHyperopt</code>.
This will create a new hyperopt file from a template, which will be located under <code>user_data/hyperopts/AwesomeHyperopt.py</code>.</p>

<p>Depending on the space you want to optimize, only some of the below are required:</p>
<ul>
<li>fill <code>buy_strategy_generator</code> - for buy signal optimization</li>
<li>fill <code>indicator_space</code> - for buy signal optimzation</li>
<li>fill <code>sell_strategy_generator</code> - for sell signal optimization</li>
<li>fill <code>sell_indicator_space</code> - for sell signal optimzation</li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p><code>populate_indicators</code> needs to create all indicators any of thee spaces may use, otherwise hyperopt will not work.</p>
</div>
<p>Optional - can also be loaded from a strategy:</p>
<ul>
<li>copy <code>populate_indicators</code> from your strategy - otherwise default-strategy will be used</li>
<li>copy <code>populate_buy_trend</code> from your strategy - otherwise default-strategy will be used</li>
<li>copy <code>populate_sell_trend</code> from your strategy - otherwise default-strategy will be used</li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Assuming the optional methods are not in your hyperopt file, please use <code>--strategy AweSomeStrategy</code> which contains these methods so hyperopt can use these methods instead.</p>
</div>
<p>Rarely you may also need to override:</p>
<ul>
<li><code>roi_space</code> - for custom ROI optimization (if you need the ranges for the ROI parameters in the optimization hyperspace that differ from default)</li>
<li><code>generate_roi_table</code> - for custom ROI optimization (if you need the ranges for the values in the ROI table that differ from default or the number of entries (steps) in the ROI table which differs from the default 4 steps)</li>
<li><code>stoploss_space</code> - for custom stoploss optimization (if you need the range for the stoploss parameter in the optimization hyperspace that differs from default)</li>
<li><code>trailing_space</code> - for custom trailing stop optimization (if you need the ranges for the trailing stop parameters in the optimization hyperspace that differ from default)</li>
</ul>
<div class="admonition tip">
<p class="admonition-title">Quickly optimize ROI, stoploss and trailing stoploss</p>
<p>You can quickly optimize the spaces <code>roi</code>, <code>stoploss</code> and <code>trailing</code> without changing anything (i.e. without creation of a "complete" Hyperopt class with dimensions, parameters, triggers and guards, as described in this document) from the default hyperopt template by relying on your strategy to do most of the calculations.</p>

<h3 id="2-configure-your-guards-and-triggers">2. Configure your Guards and Triggers<a class="headerlink" href="#2-configure-your-guards-and-triggers" title="Permanent link">&para;</a></h3>
<p>There are two places you need to change in your hyperopt file to add a new buy hyperopt for testing:</p>
<ul>
<li>Inside <code>indicator_space()</code> - the parameters hyperopt shall be optimizing.</li>
<li>Inside <code>populate_buy_trend()</code> - applying the parameters.</li>
</ul>
<p>There you have two different types of indicators: 1. <code>guards</code> and 2. <code>triggers</code>.</p>
<ol>
<li>Guards are conditions like "never buy if ADX &lt; 10", or never buy if current price is over EMA10.</li>
<li>Triggers are ones that actually trigger buy in specific moment, like "buy when EMA5 crosses over EMA10" or "buy when close price touches lower bollinger band".</li>
</ol>
<p>Hyperoptimization will, for each eval round, pick one trigger and possibly
multiple guards. The constructed strategy will be something like
"<em>buy exactly when close price touches lower bollinger band, BUT only if
ADX &gt; 10</em>".</p>
<p>If you have updated the buy strategy, i.e. changed the contents of
<code>populate_buy_trend()</code> method, you have to update the <code>guards</code> and
<code>triggers</code> your hyperopt must use correspondingly.</p>
<h4 id="sell-optimization">Sell optimization<a class="headerlink" href="#sell-optimization" title="Permanent link">&para;</a></h4>
<p>Similar to the buy-signal above, sell-signals can also be optimized.
Place the corresponding settings into the following methods</p>
<ul>
<li>Inside <code>sell_indicator_space()</code> - the parameters hyperopt shall be optimizing.</li>
<li>Inside <code>populate_sell_trend()</code> - applying the parameters.</li>
</ul>
<p>The configuration and rules are the same than for buy signals.
To avoid naming collisions in the search-space, please prefix all sell-spaces with <code>sell-</code>.</p>

<p>Let's say you are curious: should you use MACD crossings or lower Bollinger
Bands to trigger your buys. And you also wonder should you use RSI or ADX to
help with those buy decisions. If you decide to use RSI or ADX, which values
should I use for them? So let's use hyperparameter optimization to solve this
mystery.</p>
<p>We will start by defining a search space:</p>

<p>Above definition says: I have five parameters I want you to randomly combine
to find the best combination. Two of them are integer values (<code>adx-value</code>
and <code>rsi-value</code>) and I want you test in the range of values 20 to 40.
Then we have three category variables. First two are either <code>True</code> or <code>False</code>.
We use these to either enable or disable the ADX and RSI guards. The last
one we call <code>trigger</code> and use it to decide which buy trigger we want to use.</p>

<p>Hyperopting will now call this <code>populate_buy_trend</code> as many times you ask it (<code>epochs</code>)
with different value combinations. It will then use the given historical data and make
buys based on the buy signals generated with the above function and based on the results
it will end with telling you which paramter combination produced the best profits.</p>
<p>The search for best parameters starts with a few random combinations and then uses a
regressor algorithm (currently ExtraTreesRegressor) to quickly find a parameter combination
that minimizes the value of the <a href="#loss-functions">loss function</a>.</p>
<p>The above setup expects to find ADX, RSI and Bollinger Bands in the populated indicators.
When you want to test an indicator that isn't used by the bot currently, remember to
add it to the <code>populate_indicators()</code> method in your custom hyperopt file.</p>
<h2 id="loss-functions">Loss-functions<a class="headerlink" href="#loss-functions" title="Permanent link">&para;</a></h2>
<p>Each hyperparameter tuning requires a target. This is usually defined as a loss function (sometimes also called objective function), which should decrease for more desirable results, and increase for bad results.</p>
<p>By default, FreqTrade uses a loss function, which has been with freqtrade since the beginning and optimizes mostly for short trade duration and avoiding losses.</p>
<p>A different loss function can be specified by using the <code>--hyperopt-loss &lt;Class-name&gt;</code> argument.
This class should be in its own file within the <code>user_data/hyperopts/</code> directory.</p>
<p>Currently, the following loss functions are builtin:</p>
<ul>
<li><code>DefaultHyperOptLoss</code> (default legacy Freqtrade hyperoptimization loss function)</li>
<li><code>OnlyProfitHyperOptLoss</code> (which takes only amount of profit into consideration)</li>
<li><code>SharpeHyperOptLoss</code> (optimizes Sharpe Ratio calculated on the trade returns)</li>
</ul>
<p>Creation of a custom loss function is covered in the <a href="../advanced-hyperopt/">Advanced Hyperopt</a> part of the documentation.</p>
<h2 id="execute-hyperopt">Execute Hyperopt<a class="headerlink" href="#execute-hyperopt" title="Permanent link">&para;</a></h2>
<p>Once you have updated your hyperopt configuration you can run it.
Because hyperopt tries a lot of combinations to find the best parameters it will take time to get a good result. More time usually results in better results.</p>
<p>We strongly recommend to use <code>screen</code> or <code>tmux</code> to prevent any connection loss.</p>
<div class="highlight"><pre><span></span><code>freqtrade<span class="w"> </span>hyperopt<span class="w"> </span>--config<span class="w"> </span>config.json<span class="w"> </span>--hyperopt<span class="w"> </span>&lt;hyperoptname&gt;<span class="w"> </span>-e<span class="w"> </span><span class="m">5000</span><span class="w"> </span>--spaces<span class="w"> </span>all

<p>Use <code>&lt;hyperoptname&gt;</code> as the name of the custom hyperopt used.</p>

<p>Use the <code>--spaces</code> option to limit the search space used by hyperopt.
Letting Hyperopt optimize everything is a huuuuge search space. Often it
might make more sense to start by just searching for initial buy algorithm.
Or maybe you just want to optimize your stoploss or roi table for that awesome
new buy strategy you have.</p>
<p>Legal values are:</p>
<ul>
<li><code>all</code>: optimize everything</li>
<li><code>buy</code>: just search for a new buy strategy</li>
<li><code>sell</code>: just search for a new sell strategy</li>
<li><code>roi</code>: just optimize the minimal profit table for your strategy</li>
<li><code>stoploss</code>: search for the best stoploss value</li>
<li><code>trailing</code>: search for the best trailing stop values</li>
<li><code>default</code>: <code>all</code> except <code>trailing</code></li>
<li>space-separated list of any of the above values for example <code>--spaces roi stoploss</code></li>
</ul>
<p>The default Hyperopt Search Space, used when no <code>--space</code> command line option is specified, does not include the <code>trailing</code> hyperspace. We recommend you to run optimization for the <code>trailing</code> hyperspace separately, when the best parameters for other hyperspaces were found, validated and pasted into your custom strategy.</p>

<p>In some situations, you may need to run Hyperopt (and Backtesting) with the
<code>--eps</code>/<code>--enable-position-staking</code> and <code>--dmmp</code>/<code>--disable-max-market-positions</code> arguments.</p>
<p>By default, hyperopt emulates the behavior of the Freqtrade Live Run/Dry Run, where only one
open trade is allowed for every traded pair. The total number of trades open for all pairs
is also limited by the <code>max_open_trades</code> setting. During Hyperopt/Backtesting this may lead to
some potential trades to be hidden (or masked) by previosly open trades.</p>
<p>The <code>--eps</code>/<code>--enable-position-stacking</code> argument allows emulation of buying the same pair multiple times,
while <code>--dmmp</code>/<code>--disable-max-market-positions</code> disables applying <code>max_open_trades</code>
during Hyperopt/Backtesting (which is equal to setting <code>max_open_trades</code> to a very high
number).</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Dry/live runs will <strong>NOT</strong> use position stacking - therefore it does make sense to also validate the strategy without this as it's closer to reality.</p>

44/100: 135 trades. Avg profit 0.57%. Total profit 0.03871918 BTC (0.7722Σ%). Avg duration 180.4 mins. Objective: 1.94367
Buy hyperspace params:
{ &#39;adx-value&#39;: 44,
&#39;rsi-value&#39;: 29,
&#39;adx-enabled&#39;: False,
&#39;rsi-enabled&#39;: True,
&#39;trigger&#39;: &#39;bb_lower&#39;}
</code></pre></div>
<p>You should understand this result like:</p>
<ul>
<li>The buy trigger that worked best was <code>bb_lower</code>.</li>
<li>You should not use ADX because <code>adx-enabled: False</code>)</li>
<li>You should <strong>consider</strong> using the RSI indicator (<code>rsi-enabled: True</code> and the best value is <code>29.0</code> (<code>rsi-value: 29.0</code>)</li>
</ul>
<p>You have to look inside your strategy file into <code>buy_strategy_generator()</code>
method, what those values match to.</p>
<p>So for example you had <code>rsi-value: 29.0</code> so we would look at <code>rsi</code>-block, that translates to the following code block:</p>
<div class="highlight"><pre><span></span><code><span class="p">(</span><span class="n">dataframe</span><span class="p">[</span><span class="s1">&#39;rsi&#39;</span><span class="p">]</span> <span class="o">&lt;</span> <span class="mf">29.0</span><span class="p">)</span>
</code></pre></div>
<p>Translating your whole hyperopt result as the new buy-signal would then look like:</p>
<div class="highlight"><pre><span></span><code><span class="k">def</span> <span class="nf">populate_buy_trend</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">dataframe</span><span class="p">:</span> <span class="n">DataFrame</span><span class="p">)</span> <span class="o">-&gt;</span> <span class="n">DataFrame</span><span class="p">:</span>

<p>By default, hyperopt prints colorized results -- epochs with positive profit are printed in the green color. This highlighting helps you find epochs that can be interesting for later analysis. Epochs with zero total profit or with negative profits (losses) are printed in the normal color. If you do not need colorization of results (for instance, when you are redirecting hyperopt output to a file) you can switch colorization off by specifying the <code>--no-color</code> option in the command line.</p>
<p>You can use the <code>--print-all</code> command line option if you would like to see all results in the hyperopt output, not only the best ones. When <code>--print-all</code> is used, current best results are also colorized by default -- they are printed in bold (bright) style. This can also be switched off with the <code>--no-color</code> command line option.</p>

<p>If you are optimizing ROI (i.e. if optimization search-space contains 'all', 'default' or 'roi'), your result will look as follows and include a ROI table:</p>
<div class="highlight"><pre><span></span><code>Best result:

<h4 id="default-roi-search-space">Default ROI Search Space<a class="headerlink" href="#default-roi-search-space" title="Permanent link">&para;</a></h4>
<p>If you are optimizing ROI, Freqtrade creates the 'roi' optimization hyperspace for you -- it's the hyperspace of components for the ROI tables. By default, each ROI table generated by the Freqtrade consists of 4 rows (steps). Hyperopt implements adaptive ranges for ROI tables with ranges for values in the ROI steps that depend on the ticker_interval used. By default the values vary in the following ranges (for some of the most used ticker intervals, values are rounded to 5 digits after the decimal point):</p>

<p>These ranges should be sufficient in most cases. The minutes in the steps (ROI dict keys) are scaled linearly depending on the ticker interval used. The ROI values in the steps (ROI dict values) are scaled logarithmically depending on the ticker interval used.</p>
<p>If you have the <code>generate_roi_table()</code> and <code>roi_space()</code> methods in your custom hyperopt file, remove them in order to utilize these adaptive ROI tables and the ROI hyperoptimization space generated by Freqtrade by default.</p>
<p>Override the <code>roi_space()</code> method if you need components of the ROI tables to vary in other ranges. Override the <code>generate_roi_table()</code> and <code>roi_space()</code> methods and implement your own custom approach for generation of the ROI tables during hyperoptimization if you need a different structure of the ROI tables or other amount of rows (steps).

<p>After you run Hyperopt for the desired amount of epochs, you can later list all results for analysis, select only best or profitable once, and show the details for any of the epochs previously evaluated. This can be done with the <code>hyperopt-list</code> and <code>hyperopt-show</code> subcommands.

<p>Once the optimized strategy has been implemented into your strategy, you should backtest this strategy to make sure everything is working as expected.</p>
<p>To achieve same results (number of trades, their durations, profit, etc.) than during Hyperopt, please use same set of arguments <code>--dmmp</code>/<code>--disable-max-market-positions</code> and <code>--eps</code>/<code>--enable-position-stacking</code> for Backtesting.</p>
