  Subject: [amibroker] code help 
  request
  
  What 
  function(s) should I be looking at for the following pseudo code? 
  
When 
  MACD crosses positive, buy, and use the lowest price during the 
  
previous 
  negative MACD swing as a stop. 
I'm 
  pretty sure I can write the buy conditioned on the cross with little 
  
problem. 
  But at this point I have no idea how to write that stop. 
I 
  am not a programmer at all, but I once got a Unix box to output, "Hello, 
  
world!" 
  It was probably dumb luck.
