<h1 id="advanced-strategies">Advanced Strategies<a class="headerlink" href="#advanced-strategies" title="Permanent link">&para;</a></h1>
<p>This page explains some advanced concepts available for strategies.
If you're just getting started, please be familiar with the methods described in the <a href="../strategy-customization/">Strategy Customization</a> documentation first.</p>
<h2 id="custom-order-timeout-rules">Custom order timeout rules<a class="headerlink" href="#custom-order-timeout-rules" title="Permanent link">&para;</a></h2>
<p>Simple, timebased order-timeouts can be configured either via strategy or in the configuration in the <code>unfilledtimeout</code> section.</p>
<p>However, freqtrade also offers a custom callback for both ordertypes, which allows you to decide based on custom criteria if a order did time out or not.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Unfilled order timeouts are not relevant during backtesting or hyperopt, and are only relevant during real (live) trading. Therefore these methods are only called in these circumstances.</p>
</div>
<h3 id="custom-order-timeout-example">Custom order timeout example<a class="headerlink" href="#custom-order-timeout-example" title="Permanent link">&para;</a></h3>
<p>A simple example, which applies different unfilled-timeouts depending on the price of the asset can be seen below.
It applies a tight timeout for higher priced assets, while allowing more time to fill on cheap coins.</p>
<p>The function must return either <code>True</code> (cancel order) or <code>False</code> (keep order alive).</p>
