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.
