* `DecimalParameter` - defines a floating point parameter with a limited number of decimals (default 3). Should be preferred instead of `RealParameter` in most cases.
* `RealParameter` - defines a floating point parameter with upper and lower boundaries and no precision limit. Rarely used as it creates a space with a near infinite number of possibilities.
* `CategoricalParameter` - defines a parameter with a predetermined number of choices.
* `BooleanParameter` - Shorthand for `CategoricalParameter([True, False])` - great for "enable" parameters.

While this may slow down the hyperopt startup speed, the overall performance will increase as the Hyperopt execution itself may pick the same value for multiple epochs (changing other values).
You should however try to use space ranges as small as possible. Every new column will require more memory, and every possibility hyperopt can try will increase the search space.
## Optimizing protections
Freqtrade can also optimize protections. How you optimize protections is up to you, and the following should be considered as example only.
The strategy will simply need to define the "protections" entry as property returning a list of protection configurations.
``` python
from pandas import DataFrame
from functools import reduce
import talib.abstract as ta
from freqtrade.strategy import (BooleanParameter, CategoricalParameter, DecimalParameter,
IStrategy, IntParameter)
import freqtrade.vendor.qtpylib.indicators as qtpylib
class MyAwesomeStrategy(IStrategy):
stoploss = -0.05
timeframe = '15m'
# Define the parameter spaces
cooldown_lookback = IntParameter(2, 48, default=5, space="protection", optimize=True)
stop_duration = IntParameter(12, 200, default=5, space="protection", optimize=True)
use_stop_protection = BooleanParameter(default=True, space="protection", optimize=True)
@property
def protections(self):
prot = []
prot.append({
"method": "CooldownPeriod",
"stop_duration_candles": self.cooldown_lookback.value
})
if self.use_stop_protection.value:
prot.append({
"method": "StoplossGuard",
"lookback_period_candles": 24 * 3,
"trade_limit": 4,
"stop_duration_candles": self.stop_duration.value,
"only_per_pair": False
})
return protection
def populate_indicators(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
# ...
```
You can then run hyperopt as follows:
`freqtrade hyperopt --hyperopt-loss SharpeHyperOptLossDaily --strategy MyAwesomeStrategy --spaces protection`
!!! Note
The protection space is not part of the default space, and is only available with the Parameters Hyperopt interface, not with the legacy hyperopt interface (which required separate hyperopt files).
Freqtrade will also automatically change the "--enable-protections" flag if the protection space is selected.
!!! Warning
If protections are defined as property, entries from the configuration will be ignored.
It is therefore recommended to not define protections in the configuration.
### Migrating from previous property setups
A migration from a previous setup is pretty simple, and can be accomplished by converting the protections entry to a property.
In simple terms, the following configuration will be converted to the below.
``` python
class MyAwesomeStrategy(IStrategy):
protections = [
{
"method": "CooldownPeriod",
"stop_duration_candles": 4
}
]
```
Result
``` python
class MyAwesomeStrategy(IStrategy):
@property
def protections(self):
return [
{
"method": "CooldownPeriod",
"stop_duration_candles": 4
}
]
```
You will then obviously also change potential interesting entries to parameters to allow hyper-optimization.
## Loss-functions
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.

!!! Note "Backtesting"
Protections are supported by backtesting and hyperopt, but must be explicitly enabled by using the `--enable-protections` flag.
!!! Warning "Setting protections from the configuration"
Setting protections from the configuration via `"protections": [],` key should be considered deprecated and will be removed in a future version.
It is also no longer guaranteed that your protections apply to the strategy in cases where the strategy defines [protections as property](hyperopt.md#optimizing-protections).
