!!! Note "Durations"
Durations (`stop_duration*` and `lookback_period*` can be defined in either minutes or candles).
For more flexibility when testing different timeframes, all below examples will use the "candle" definition.
#### Stoploss Guard
`StoplossGuard` selects all trades within `lookback_period` (in minutes), and determines if the amount of trades that resulted in stoploss are above `trade_limit` - in which case trading will stop for `stop_duration`.
`StoplossGuard` selects all trades within `lookback_period`, and determines if the amount of trades that resulted in stoploss are above `trade_limit` - in which case trading will stop for `stop_duration`.
This applies across all pairs, unless `only_per_pair` is set to true, which will then only look at one pair at a time.
The below example stops trading for all pairs for 2 hours (120min) after the last trade if the bot hit stoploss 4 times within the last 24h.
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.

`MaxDrawdown` uses all trades within `lookback_period` (in minutes) to determine the maximum drawdown. If the drawdown is below `max_allowed_drawdown`, trading will stop for `stop_duration` (in minutes) after the last trade - assuming that the bot needs some time to let markets recover.
The below sample stops trading for 12 hours (720min) if max-drawdown is > 20% considering all trades within the last 2 days (2880min).

`LowProfitPairs` uses all trades for a pair within `lookback_period` (in minutes) to determine the overall profit ratio.
If that ratio is below `required_profit`, that pair will be locked for `stop_duration` (in minutes).
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 hours (360min).

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.
The below example:
The below example assumes a timeframe of 1 hour:
* Locks each pair after selling for an additional 10 minutes (`CooldownPeriod`), giving other pairs a chance to get filled.
* Stops trading if the last 2 days had 20 trades, which caused a max-drawdown of more than 20%. (`MaxDrawdown`).
* Stops trading if more than 4 stoploss occur for all pairs within a 1 day (1440min) limit (`StoplossGuard`).
* Locks all pairs that had 4 Trades within the last 6 hours (`60 * 6 = 360`) with a combined profit ratio of below 0.02 (<2%) (`LowProfitPairs`).
* Locks all pairs for 120 minutes that had a profit of below 0.01 (<1%) within the last 24h (`60 * 24 = 1440`), a minimum of 4 trades.
* Locks each pair after selling for an additional 5 candles (`CooldownPeriod`), giving other pairs a chance to get filled.
* Stops trading for 4 hours (`4 * 1h candles`) if the last 2 days (`48 * 1h candles`) had 20 trades, which caused a max-drawdown of more than 20%. (`MaxDrawdown`).
* Stops trading if more than 4 stoploss occur for all pairs within a 1 day (`24 * 1h candles`) limit (`StoplossGuard`).
* Locks all pairs that had 4 Trades within the last 6 hours (`6 * 1h candles`) with a combined profit ratio of below 0.02 (<2%) (`LowProfitPairs`).
