InvestorHubFx Signals show the saved studies. You have the option to pick or remove a study. Picking studies, you can combine a bunch of studies using an “OR” or an “AND” specification.  
You can select up to four studies. Then, start the signals and the tool creates alerts when the criteria are met. 

If you select the OR specification, you will be alerted if ANY of the (let’s say four) signals are active. If you select AND, then you need ALL four studies to be active at the present moment. Active means not only that a signal arrived just now, but also being within the “Checkpoint” period you selected when you were analyzing the study. For example, if we save a MA cross with a checkpoint equal to 10, this signal will be shown as “active” even if the cross arrived 9 bars ago. But the alert comes only if the cross happened at the closing of the previous bar.  

Clicking on Active Signals on the bottom of the right side, then traders can check the Overall picture of the picked signals. 

Our saved studies, RSI [D1] and Bollinger Bands [D1], seem to be active now for some bars. No more bars than the selected “Checkpoint” period. So we had an RSI signal, no more than 4 bars (days) ago, and a BB signal no more than 8 days ago. It seems that it is a perfect opportunity to go long. Let’s check:

Yes! It seems that the market has been going up for 3 days now.. It was a perfect signal, generated by us, using the screener and by saving some studies!
