After running a model, signals silently pop up in the Signal Hub - a dialog that's always behind the model when I'm working on the laptop. Did I get any signals? Don't know... Menu.. Window.. Signal Hub. Oh, nope, nothing today. That process is painful. I want how many signals were generated after a backtest right on the model dialog, and, by clicking that indication open the Signal Hub.

This indicator creates a ratio by dividing any two fundamental items and/or price components and applying optional summing and multiplication. In order to see any useful results with FundamentalRatio, you'll first need to enable some fundamental data in Quantacula Studio.

An alert quote manager is required to operate this script properly because you cannot send every order at once, just create the alert as in previous versions of older PERL script WL and that should make it possible to use in Quantacula.
