This section is where you specify a formula that will identify the indicator’s long trade signal. The top pull-down sets the formula, and the lower field is the value. A decimal value can be specified, such as 0.9.
Typically, an indicator will output a +1 value for a long signal. A -1 value for a short signal. And, 0 (zero) for no signal. Sometimes an indicator will identify various types of long signals, in which case it may output +1, or +2, or +3 to identify the different types of long signals. You will need to contact the vendor who provided the indicator for that type of information.
