QT Light lets you visualize all Logical Invest strategies, sub-strategies, settings, metrics, etc. It also allows you to issue ‘signals’ (i.e. see current model allocations) at any time, not just on the 1st day of the month.
QT Premium lets you additionally: 1. Import your own symbols 2. Customize pre-existing strategies or create new ones. 3. Mix our (or your) strategies into your own dynamic ‘meta-strategies'(portfolios that dynamically pick and combine strategies).
An example would be an investor who likes our Universal Investment strategy (SPY/HEDGE) but wants to replace SPY with QQQ. The could create a custom UIS_qqq_version, backtest it, find robust parameters and then use it to issue their own signals.
