This is what I call an "after-weekend continuation". The bears have control of the GBPNZD, and many bears would've exited on Friday to limit their exposure over the weekend. A good place to re-enter would be Friday's high, which is where I went short. I took profit just above support, marked below.
I spotted a bearish engulfing candle at the close of Monday, and went short on Tuesday. This was a standard trade, and saw enough scope for a 1R reward before I'd hit support.
I had went short the previous week after seeing a bearish engulfing candle. I'd set my reward at 1R, and price came within 5 pips of hitting my target before reversing. Shorting the AUD is expensive, and I was losing about 1% of my profit for every day I held the trade open. Holding the trade overnight on Wednesday would've cost me 3% of my trade, since the overnight swap is usually tripled on Wednesdays to account for Saturday and Sunday. Rather than lose 3%, I decided to exit the trade with a tiny 0.2R reward.
I think I mismanaged this trade. I spotted a low volatility candle at the end of a retracement, and went short at the break of its low. Price did break downward for awhile, but then returned back to my entry point, so I decided to scratch the trade and got out at breakeven. If I had kept the trade open, I'd still be in it.
I went long on the CADJPY after spotting a small, shallow retracement, and got stopped out the next day. The previous day's high behaved as resistance and stopped price from advancing upwards.
Avoid shorting the AUD (and NZD). Holding overnight positions is just too expensive.
