The other properties are for when to use or not use the signal. By default, the signal is used for every decision direction but if the settings are set to false they will be excluded. When for example the script has 3 indicators, a BBands, MACD, and RSI. When the 'useShort' of the RSI is unchecked and we connect all indicators result to a GetUnanimousSignal command, only the BBands & MACD have to signal short for a final short decision. But for a final long signal, all 3 need to agree.
