Hi, This can occur if the condition was never true within all the data tested. Certain formula functions can return a N/A value (such as ValueWhen() ). Load Minimum Records just makes it more likely to see the message since you are testing a smaller data amount. Loading more data gives you more opportunity for a signal to have occurred in the past, but it does not guarantee a signal. That is ultimately what this message means - It is not true today and has never been true in the entirety of the data sample. If it was true at least once in the history of the tested data, you would have a "Normal Filter Rejection" (or a 0 if the formula was in a non-Filter column). Without knowing your formula or what securities you are running the scan against it is hard to say for certain what is happening. Are you testing on a single security or multiple securities? If you plot your indicator in a chart of one of the rejected securities, do you see the indicator equal to 1 ever?
