# Advanced Strategies
|
||
|
|
|
||
|
|
This page explains some advanced concepts available for strategies.
|
||
|
|
If you're just getting started, please be familiar with the methods described in the [Strategy Customization](strategy-customization.md) documentation first.
|
||
|
|
|
||
|
|
## Custom order timeout rules
|
||
|
|
|
||
|
|
Simple, timebased order-timeouts can be configured either via strategy or in the configuration in the `unfilledtimeout` section.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
!!! Note:
|
||
|
|
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.
|
||
|
|
|
||
|
|
### Custom order timeout example
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
The function must return either `True` (cancel order) or `False` (keep order alive).
|
||
|
|
|
||
|
|
``` python
|
||
|
|
from datetime import datetime, timestamp
|
||
|
|
from freqtrade.persistence import Trade
|
||
|
|
|
||
|
|
class Awesomestrategy(IStrategy):
|
||
|
|
|
||
|
|
# ... populate_* methods
|
||
|
|
|
||
|
|
# Set unfilledtimeout to 25 hours, since our maximum timeout from below is 24 hours.
|
||
|
|
unfilledtimeout = {
|
||
|
|
'buy': 60 * 25,
|
||
|
|
'sell': 60 * 25
|
||
|
|
}
|
||
|
|
|
||
|
|
def check_buy_timeout(self, pair: str, trade: Trade, order: dict, **kwargs) -> bool:
|
||
|
|
if trade.open_rate > 100 and trade.open_date < datetime.utcnow() - timedelta(minutes=5):
|
||
|
|
return True
|
||
|
|
elif trade.open_rate > 10 and trade.open_date < datetime.utcnow() - timedelta(minutes=3):
|
||
|
|
return True
|
||
|
|
elif trade.open_rate < 1 and trade.open_date < datetime.utcnow() - timedelta(hours=24):
|
||
|
|
return True
|
||
|
|
return True
|
||
|
|
|
||
|
|
|
||
|
|
def check_sell_timeout(self, pair: str, trade: Trade, order: dict, **kwargs) -> bool:
|
||
|
|
if trade.open_rate > 100 and trade.open_date < datetime.utcnow() - timedelta(minutes=5):
|
||
|
|
return True
|
||
|
|
elif trade.open_rate > 10 and trade.open_date < datetime.utcnow() - timedelta(minutes=3):
|
||
|
|
return True
|
||
|
|
elif trade.open_rate < 1 and trade.open_date < datetime.utcnow() - timedelta(hours=24):
|
||
|
|
return True
|
||
|
|
return True
|
||
|
|
```
|
||
|
|
|
||
|
|
!!! Note:
|
||
|
|
For the above example, `unfilledtimeout` must be set to something bigger than 24h, otherwise that type of timeout will apply first.
