<p class="admonition-title">Beta feature</p>
<p>This feature is still in it's testing phase. Should you notice something you think is wrong please let us know via Discord, Slack or via Github Issue.</p>
</div>
<p>Protections will protect your strategy from unexpected events and market conditions by temporarily stop trading for either one pair, or for all pairs.
All protection end times are rounded up to the next candle to avoid sudden, unexpected intra-candle buys.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Not all Protections will work for all strategies, and parameters will need to be tuned for your strategy to improve performance.<br />
To align your protection with your strategy, you can define protections in the strategy.</p>
</div>
<div class="admonition tip">
<p class="admonition-title">Tip</p>
<p>Each Protection can be configured multiple times with different parameters, to allow different levels of protection (short-term / long-term).</p>

<p class="admonition-title">Durations</p>
<p>Durations (<code>stop_duration*</code> and <code>lookback_period*</code> can be defined in either minutes or candles).
For more flexibility when testing different timeframes, all below examples will use the "candle" definition.</p>
</div>
<h4 id="stoploss-guard">Stoploss Guard<a class="headerlink" href="#stoploss-guard" title="Permanent link">&para;</a></h4>
<p><code>StoplossGuard</code> selects all trades within <code>lookback_period</code> in minutes (or in candles when using <code>lookback_period_candles</code>).
If <code>trade_limit</code> or more trades resulted in stoploss, trading will stop for <code>stop_duration</code> in minutes (or in candles when using <code>stop_duration_candles</code>).</p>
<p>This applies across all pairs, unless <code>only_per_pair</code> is set to true, which will then only look at one pair at a time.</p>
<p>The below example stops trading for all pairs for 4 candles after the last trade if the bot hit stoploss 4 times within the last 24 candles.</p>

<p><code>StoplossGuard</code> considers all trades with the results <code>"stop_loss"</code>, <code>"stoploss_on_exchange"</code> and <code>"trailing_stop_loss"</code> if the resulting profit was negative.
<code>trade_limit</code> and <code>lookback_period</code> will need to be tuned for your strategy.</p>

<h4 id="maxdrawdown">MaxDrawdown<a class="headerlink" href="#maxdrawdown" title="Permanent link">&para;</a></h4>
<p><code>MaxDrawdown</code> uses all trades within <code>lookback_period</code> in minutes (or in candles when using <code>lookback_period_candles</code>) to determine the maximum drawdown. If the drawdown is below <code>max_allowed_drawdown</code>, trading will stop for <code>stop_duration</code> in minutes (or in candles when using <code>stop_duration_candles</code>) after the last trade - assuming that the bot needs some time to let markets recover.</p>
<p>The below sample stops trading for 12 candles if max-drawdown is &gt; 20% considering all pairs - with a minimum of <code>trade_limit</code> trades - within the last 48 candles. If desired, <code>lookback_period</code> and/or <code>stop_duration</code> can be used.</p>

<h4 id="low-profit-pairs">Low Profit Pairs<a class="headerlink" href="#low-profit-pairs" title="Permanent link">&para;</a></h4>
<p><code>LowProfitPairs</code> uses all trades for a pair within <code>lookback_period</code> in minutes (or in candles when using <code>lookback_period_candles</code>) to determine the overall profit ratio.
If that ratio is below <code>required_profit</code>, that pair will be locked for <code>stop_duration</code> in minutes (or in candles when using <code>stop_duration_candles</code>).</p>
<p>The below example will stop trading a pair for 60 minutes if the pair does not have a required profit of 2% (and a minimum of 2 trades) within the last 6 candles.</p>

<h4 id="cooldown-period">Cooldown Period<a class="headerlink" href="#cooldown-period" title="Permanent link">&para;</a></h4>
<p><code>CooldownPeriod</code> locks a pair for <code>stop_duration</code> in minutes (or in candles when using <code>stop_duration_candles</code>) after selling, avoiding a re-entry for this pair for <code>stop_duration</code> minutes.</p>
<p>The below example will stop trading a pair for 2 candles after closing a trade, allowing this pair to "cool down".</p>

"method": "CooldownPeriod",
"stop_duration_candles": 2

<div class="admonition note">
<p class="admonition-title">Note</p>
<p>This Protection applies only at pair-level, and will never lock all pairs globally.
This Protection does not consider <code>lookback_period</code> as it only looks at the latest trade.</p>

<p>All protections can be combined at will, also with different parameters, creating a increasing wall for under-performing pairs.
All protections are evaluated in the sequence they are defined.</p>
<p>The below example assumes a timeframe of 1 hour:</p>
<ul>
<li>Locks each pair after selling for an additional 5 candles (<code>CooldownPeriod</code>), giving other pairs a chance to get filled.</li>
<li>Stops trading for 4 hours (<code>4 * 1h candles</code>) if the last 2 days (<code>48 * 1h candles</code>) had 20 trades, which caused a max-drawdown of more than 20%. (<code>MaxDrawdown</code>).</li>
<li>Stops trading if more than 4 stoploss occur for all pairs within a 1 day (<code>24 * 1h candles</code>) limit (<code>StoplossGuard</code>).</li>
<li>Locks all pairs that had 4 Trades within the last 6 hours (<code>6 * 1h candles</code>) with a combined profit ratio of below 0.02 (&lt;2%) (<code>LowProfitPairs</code>).</li>
<li>Locks all pairs for 2 candles that had a profit of below 0.01 (&lt;1%) within the last 24h (<code>24 * 1h candles</code>), a minimum of 4 trades.</li>
