 Hi Dane, 
  
Using expand first is an aggressive way of trading 
... it provides early signals or warnings if you prefer ... If you use multiple 
indicators and multiple time frames I feel you would be safe. 
  
By multiple I don't mean you need lots of them. I 
use CCI and MACD on 2 or 3 time frames and look at stochastics to make sure 
issue is not in oversold or overbought area.  
  
In summary, I think it is well worth the risk of 
early signals. The 3x and 9x time frames I chose are quite arbitrary and were 
for initial functionality test only. 
  
You need to test and select the appropriate time 
frames to suit your style.

  system (was Re: Swing Trading - Strategy Performance) 
  
  Just out of curiosity, how safe is it to build a trading system 
  that re-expands the compressed time zone with expandFirst?  I am 
  able to get incredible backtest results from this system.  I just wonder 
  if its too good to be true because it is looking into the future?  How 
  does AB's backtester walk through time?  Does it only calculate a point 
  in time based on the past bars, including when it compresses into another time 
  zone?
  Thanks for any information anyone can share - before I start 
  trading real capitol I want to have a better idea if its going to work for 
  real?
