AUD/JPY Put Ratio Back Spread:
One can build AUDJPY put ratio back spread regardless of swings by improving odds in its positions as explained below. That In-The-Money puts on short side in put ratio back-spreads are always at risk of exercise if the market tumbles, but you have two advantages.
Firstly, keeping maximum tenor on long side: Giving a longer time to expiration for long sides, any abrupt drastic moves on the downside so that assignment can be covered by the long puts.
Secondly, time decay advantage: Using near month contracts or contracts shorter tenor on short side signifies the importance of entering the position when IV is lower than average but AUDJPY IV is seen at 10% which is quite higher side (due to data season), so let us keep maturity on short side as normal as near month contract period. Time decay and implied volatility work in your favor on the short puts.
