2 Moving Averages, MA11 and MA31, close. Safe gains, stop loss at break even. It's not every penny you could make but it is a safe way I made a few bucks last week while testing new ways to spot check another system/method I am using.
$52 worth of gold movements last week wasn't too bad for a system so simple.
Enter/close when the two MA's cross. If they are too close, sit it out. You can add other indicators such as RSI methods too but just wants to focus on this alone in this test.
Don't let this chart fool you, there were a few trades exited but for $1 movement losses; either stop loss at break-even or manually when it got "hairy".
