2/20 Day EMA Breakout System

To create the 2/20-Day EMA Breakout System by David Landry in MetaStock for Windows, choose System Tester from the Tools menu. Now choose new and enter the following system test rules and options:

Signal Formulas
Enter Long
Alert(Cross(Sum(L > Mov(C,20,E),2) = 2,.5),10) AND HIGH >= Peak(1,Cross(Sum(L > Mov(C,20,E),2) = 2,.5) *
HHV(H,2),1) + .001{10 ticks} AND BarsSince(Cross(Sum(L > Mov(C,20,E),2) = 2,.5)) <
BarsSince(LOW <= Mov(C,20,E))
Close Long
LOW <= Mov(C,20,E)
Enter Short
Alert(Cross(Sum(H < Mov(C,20,E),2) = 2,.5),10) AND LOW <= Peak(1,Cross(Sum(H < Mov(C,20,E),2) = 2,.5) *
LLV(L,2),1) - .001{10 ticks} AND BarsSince(Cross(Sum(H < Mov(C,20,E),2) = 2,.5)) < BarsSince(HIGH >= Mov(C,20,E))
Close Short
HIGH >= Mov(C,20,E)
  • Initial equity Points Only
  • Positions Long and short
  • Trade price Close
  • Trade delay 0

Please note the {10 ticks} comment in the system rules. The value used in these rules is for most currencies. You should change this value based upon the commodity your testing.
