I have used a 2.0 calculation in the AUDCAD to get a proper, tight PRZ. If the price comes in the zone, I suggest to watch price action briefly:
1. Wait till the candle closes INSIDE the PRZ, with both borders hit by the up and down wick of the closing candle.
2. Switch to a lower timeframe to execute the order when seeing a confirmation candle like a or a .
3. I've set up 2 targets to cover half of my position at target 1 and I will set my stop-loss to break-even. The other half gets covered at target 2.
May the pips be with you,
