When you have 'Signal config' enabled in the signaler configuration, the trading bot will use the configuration of the Signaler for the position that your trading bot will open.
For example, if a Signaler uses Percentage profit and Stop loss, your trading bot will use these settings for the position your bot opened, which will overrule your Base config and Config pool settings.
Please note that when enabled, the sell settings of positions opened based on a trading signal will not change after you update your own Base config or Config pool settings.
