Re: [amibroker] question on formula for plot trade price

Use exrem() to get rid of unwanted signals.  You can also use plotshapes() to 
plot buy/sell arrows.

  Subject: [amibroker] question on formula for plot trade price


  hello, 

  I am new to amibroker and am trying to figure this one out. 

  I have a simple formula 
  BuyCond1= EMA(  Close , 15 ) > EMA(  Close , 100 );


  Buy = Buycond1 ;

  Sell = EMA (Close,15)<EMA(Close,100);

  I am trying to plot the trade price on the chart. so far I have this:


   Plot(C,"Price", colorBlack, styleLine ); 
  Plot(EMA(C,15),"ema", colorRed ); 


  for( i = 0; i < BarCount; i++ )
  {
  if( Buy[i] ) PlotText( "Buy\n@" + C[ i ], i, L[ i ], colorGreen );
  if( Sell[i] ) PlotText( "Sell\n@" + C[ i ], i, H[ i ], colorRed, colorYellow 
);

  WHen I apply indicator it plots the price at every point on the chart and not 
just when the moving averages cross. Does anyone know why? and can show me the 
formula??? 

  It would be much appreciated.

  thanks
