### Configuring amount per trade
@ -679,13 +677,12 @@ freqtrade
When working with larger timeframes (for example 1h or more) and using a low `max_open_trades` value, the last candle can be processed as soon as a trade slot becomes available. When processing the last candle, this can lead to a situation where it may not be desirable to use the buy signal on that candle. For example, when using a condition in your strategy where you use a cross-over, that point may have passed too long ago for you to start a trade on it.
In these situations, you can enable the functionality to ignore candles that are beyond a specified period by setting `ask_strategy.ignore_buying_expired_candle` to `true`. After this, you can set `ask_strategy.ignore_buying_expired_candle_after` to the number of seconds after which the candle becomes expired.
In these situations, you can enable the functionality to ignore candles that are beyond a specified period by setting `ask_strategy.ignore_buying_expired_candle_after` to a positive number, indicating the number of seconds after which the candle becomes expired.
For example, if your strategy is using a 1h timeframe, and you only want to buy within the first 5 minutes when a new candle comes in, you can add the following configuration to your strategy:
``` jsonc
"ask_strategy":{
"ignore_buying_expired_candle" = true
"ignore_buying_expired_candle_after" = 300 # 5 minutes
"price_side": "bid",
// ...
