METASTOCK: TRIX

In his article "Trading In Tempo With TRIX," Jongseon Kim presents a trading system based on the TRIX indicator. This indicator is built into MetaStock and does not need to be defined in a custom formula. The formulas that follow create an exploration and a system test based on his conditions.

To create this exploration in MetaStock, go to Tools and select the Explorer. Click "New" and enter a name ("Trix system"). Then enter the following formulas in the corresponding tabs:
 

TRIX system
     COLUMN FORMULAS
         ColumnA: gold X
             tx:=TRIX(5);
             sig:=Mov(tx,3,E);
             Cross(tx,sig)
 
         ColumnB: Fall
             tx:=TRIX(5);
             Cross(0,ROC(tx,1,$))
 
     FILTER
         Formula:
             colA OR colB

To recreate the system test in MetaStock, go to Tools and select System Tester. Click "New" and enter a name ("Trix system"). Under the corresponding tabs, enter the following formulas:
 

TRIX System
         Enter Long:
             tx:=TRIX(5);
             sig:=Mov(tx,3,E);
             Cross(tx,sig)
 
         Close Long:
             tx:=TRIX(5);
             Cross(0,ROC(tx,1,$))

Using the four conditions defined, it is also possible to create an expert advisor. Figure 3 shows a chart with such an expert attached.
