DeMarker Indicator Strategy (Amibroker Code)

The original article can be found here.

The code in plain English:

• We use a 3-day lookback period
• We buy when DeMarker indicator is below 5
• We sell when the close is higher than yesterday’s high

Amibroker code:

oddis=Optimize("Trading day",3,2,8,1);
setOption("holdminbars",1);

highm = IIF( H > Ref( H, -1 ), H - Ref( H, - 1), 0 );
lowm = IIF( L < Ref( L, -1 ), Ref( L, - 1 ) - L, 0 );

DeMarker = 100 * Sum( highm, oddis )/( Sum( lowm, oddis ) + Sum( highm, oddis ) );

graph0 = DeMarker;

Buy = Demarker <5;
BuyPrice= Close;
Sell =    C>Ref(H,-1) ;
sellPrice=Close;
