Could just as easily have 2 losses from 2 trades - far worse than 1 loss, right?
And it's not twice the risk since the AUD long and short offset each other.
I think you're missing the mathematical point here. By going short EU and long EA you -
assuming equal sized trades - you net out to long AU. If EA makes a move larger than EU then it means a comparable move in AU. It has to because of the triangular arbitrage. The only difference is you're paying 2 spreads instead of one, so your net return is lower by doing the synthetic than the straight position.
Maybe its because your assumption's incorrect . ( highlighted)
Still have to disagree John and will have to give you an example
The EA can move in say approx 30 mins up to 3 times more than the EU - and similar or even in some case 5 + time more than the AU in my sessions of the 24 hr trading day
I notice this every day as a intraday trader - not just a scalper but trading for targets of 7 to 25+ pips ( ie not true scalping)
I am sure I can find one out from this week to give you a P& L on it
My spreads and costs on the EU will be approx. 1 pip - AU say 1.3 pips and EA between 2.3 and 3 pips in total
Ok - I can simultaneously scalp all 3 pairs - with 2 in opposite directions on one pair from a key time - and the moves can end up like this in say 20 mins - or what ever time they all stall.
EU might make a new move of say 9 to 15 pips
EA will move in same time 20 to 35+ pips
AU - might make 8 pips up 12 pips top ( less of a mover in European session )
The moves and spread costs result with the pair with the highest spread EA - still making me more money ( That's all we should be concerned with than the pips etc ) even if I pro rata the stake size - needing a larger stop of say 6 or 7 pips on the EA compared with the 3 pip - 4 pip stop size with the EU.
The fact the my win ratios over 20k live trades average around 70% - then although yes - I can still have a bad period of 7 losses in a row - I expect to have more winning trades every day than losing trades.
I would agree with you if the ratio of the EA moves to the EU or EA were a lot closer in size - but they are out of sync to such a degree that I don't even know why experienced retail intraday traders even bother majoring on the EU.
There will always be exceptions to the norm - especially in trading - I don't normally intraday trade the AJ - but I am sure its a far more cost effective pair to trade than the UJ most of the time
