Re: [amibroker] PositionScore Suggestions for Chris

["Joe Landry" <jelandry@xxxxxxxxxxxxx>]

Chris - This is a collection coming out of my info database and not Amibroker - so each line should be verified as executable and this is only presented here as ideas that've been tried.  You could assemble them in one large FUNCTION module and call each scoring routine in turn to test it out in your strategy.

Like calling the first one as a function as follows: 

PositionScore = BeatenDownStocks(30); 

Hope this helps and interested in your testing.

SCORING ROUTINES 

Beaten Down Stocks/Mutual Funds

// =============== written as a function ======================
function BeatenDownStocks(Length)
{
 Result = EMA(C,Length)/C;

 } 
 return Result;

// ======================================================

Efficiency Index 

Result = (C - Ref(C,-Lookback)) / ATR(Lookback);

Momentum Equation (Columbine, QP2, IBD) 

QRSRAW = ( (C / Ref(C,-62)) * 0.4 ) + 

( (Ref(C,-63) / Ref(C,-125)) * 0.2 ) +

( (Ref(C,-126) / Ref(C,-188)) * 0.2 ) +

( (Ref(C,-189) / Ref(C,-251)) * 0.2 );

Result = QRSRaw;

Most Anchored Momentum 

// Most Anchored Momentum -

// An outgrowth of a MA filter is that the MA is delayed by the period/2.

// To get the coincident average of a price N ticks ago, use a period or

// N*2 for the MA. This is used to "anchor" the demonimator of the

// momentum calculation.

smaper = 2 * momper + 1;

Result = (100 * ((price / MA(price, smaper)) - 1));

Momentum 

Result = (100 * ((price / Ref(price, -momper)) - 1))

Relative TIming 

RT = Close / MA(Close,65);

Result = RT;

Bollinger Band(watch out - negative scores will SHORT a position) 

BBandWidth = 2;

UBB = BBandTop(Close, 20, BBandWidth);

LBB = BBandBot(Close, 20, BBandWidth);

PositionScore = 100 - 100 * (Close - LBB) / (UBB - LBB);

maybe this is better... 

PositionScore = abs(100 - 100 * (Close - LBB) / (UBB - LBB));

  I'm currently building a system that utilizes trend line cross overs.

  Just want to sruvey the community to see what positionscore methods 
  people utilize.

  I've tried 1/ATR(20) to some success, but would like to see what 
  other creations may be out there.
