Re: [amibroker] USE OF [ ]

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

No, in AMiBRoker you should use Ref function
http://www.amibroker.com/f?Ref


Buy = MyMA > Ref( MyMA, - R);

[ ] - operator is for accessing individual array ELEMENTS.

Must-read for everyone:

  Hello,

  I am a french trader and user of amibroker( former TS user ) ,and I always have the same problems with array identifiers. 

  On TS, you simply use a variables between the brackets, but on ami, it seems like you have to put [barcount - var]...

  Anyone can help me and tell where the error is in this code. It's a simple mov avg system referring to the past value of the mov avg:

  Amount = Param( "dollz", 10000, 50, 1000000, 50 );
  defMAL = Param("MAL", 10, 2, 200, 10 );
  defR = Param( "Recul", 30, 2, 30, 2 );

  MAL = Optimize( "MAL", defMAL, 2, 100, 5 );
  R = Optimize( "Recul", defR, 1, 20, 2 );

  PositionSize = Amount;

  MyMA = MA( Close, MAL );

  Buy = MyMA > MyMA[BarCount - R];
  Sell = MyMA < MyMA[BarCount - R];

  Short = MyMA < MyMA[BarCount - R];
  Cover = MyMA > MyMA[BarCount - R];


  Thanks for your help.
