To get you started though, here is one that works pretty well for intermittent trading as you described on stocks like CPQ, BNYN have worked well with it. It was originally developed for currency, but you can run it against just one stock and play with the stop loss (make a % opr larger $ value)
Pathfinder Currency Trading System (described in the October 1996 interview with Nelson Freeburg). Just copy and paste the "Mov..." parts into the appropriate windows under a New trading system.
Enter Long:
Mov(C,6,S) > Ref(Mov(C,6,S),-1) AND
Mov(P,3,S) > Mov(P,25,S) AND
Alert(Cross(Mov(C,9,S),Mov(C,18,S)),10)
Close Long:
Cross(Mov(C,18,S),Mov(C,9,S))
Enter Short:
Mov(C,6,S) < Ref(Mov(C,6,S),-1) AND
Mov(P,3,S) < Mov(P,25,S) AND
Alert(Cross(Mov(C,18,S),Mov(C,9,S)),10)
Close Short:
Cross(Mov(C,9,S),Mov(C,18,S))
Maximum Loss Stop:
Long and short positions
Maximum loss of 0.016 points.
Initial equity:
Points only
Positions:
Long and short
Trade Price:
Open
Trade delay:
1
Note that the maximum stop loss amount should be changed to 0.02 for Canadian dollars when testing these contracts.
For currency trading, open two charts, one of the desired currency and the other of Treasury bonds. For this example, I used the Swiss Franc. Choose Tile from the Window menu so both charts are visible. Drag the T-bonds price bar and drop it on the heading of the currency chart. Your currency chart should now have T-bonds plotted in the top inner window of the chart. Click on the T-bonds plot in the currency chart so it's selected (that is, little squares appear on the price bars). You will need to select the T-bonds plot each time before running a system test. The selected plot tells the MetaStock System Tester what to use for "P". Next, choose System Tester from the Tools menu, and then New to create a new system. Enter the following system rules, stops, and options and then run the test.
