AUDCAD: potential nice short

A nice potential shorting opportunity is presenting itself on AUDCAD. The signal is already printed, but we enter when it retraces 2 candles back with a sell limit order, stoploss loss should be placed where the dash printed above the signal. This is calculated by taking the highest high from the last 5 bars and then adding it to 1 * atr. Once price has moved 1 atr in your direction, move stoploss to breakeven and then let it roll down as much as you prefer with a zero-risk trade. If it comes back and hit your stop loss, you will be out of trade without any loss, and you can enter again if setup is not invalidated.
Good luck everyone.
