RE: [amibroker] Re: Help with AFL for simple system/test

["Creztor Tessel" <creztor@xxxxxxxxxxx>]

Hi thanks for that it was very close.  Ive attached two pictures to try and 
clarify things.  SMI_trade only trades/plots long if it is above 0 and 
positive/rising and only shorts/plots short if it is below 0 and decreasing. 
  As soon as either of these is not true (ie above 0 and negative or flat it 
closes any trades or does not trade).  I edited your indicator to only show 
one line and changed the colours so its very close but I am not sure how to 
set it so that it does not trade if above 0 but flat/negative or below 0 but 
flat/rising.  Ultimately I am trying to get it to optimize the (range, 
ema1,ema2) values for buy/sell.  Thanks very much for the work you did.

Jolon
