Try this method.
1) Open a position
2) Assuming you're right, it climbs a bit (if it doesn't exit with stop loss)
3) At the point you start thinking, "Hm, should I take the money out?" close half the position and move the stop to breakeven.
4) Let the other half run. It will either fall back to B/E and hit the stop (you win 50%) or it will go on to make even more profit and you just move the stop up to account for noise or below higher lows or below support lines etc.
When I stop pissing about through boredom, this method does earn extra pips on FX.
