SetPositionSize( POS_SIZE, spsShares ); 
//SetPositionSize( POS_SIZE, spsShares * ( sell == sigScaleOut ) );
SetPositionSize( POS_SIZE, spsShares * ( Cover == sigScaleOut ) );

As written in the manual http://www.amibroker.com/guide/h_pyramid.html both sigScaleIn AND sigScaleOut should be assigned to Buy/Short variable. Only full exit signals (not scaling) should be assigned to Sell/Cover.

Quote:

All you have to do to implement pyraminding is to:

  • Assign sigScaleIn to BUY/SHORT variable if you want to scale-in (increase size of) LONG/SHORT position
  • Assign sigScaleOut to BUY/SHORT variable if you want to scale-out (decrease size of) LONG/SHORT position
