cBots just don't work. I'm about to give up.

I'm starting to come to the conclusion that this platform has not evolved enough to be of any use to a serious robot trader.  

Even output values from built in indicators are completely different than those shown in on their charts.   

Take for example the Aroon Indicator in my screenshot.  According to the backtest chart the Down line had a value of 11 at 14:00, but according to the print function it was at 100! which caused my cBot to enter a bad trade.    

Now, perhaps I'm just doing something wrong, but there is NO documentation or examples I can find to prove otherwise.. 

In this case, all I'm doing is initializing the indicator in the OnStart Method 

    ar = Indicators.Aroon(7);

Then I call print method in the event method.    

    Print("{0}, {1}", ar.Up.LastValue, ar.Down.LastValue);

At this point, I'm near fed up with this system for automated trading.  Indicators (even custom indicators) don't seem to be providing cBots with valid data. I don't feel that it can be trusted with real money at all.
