Well multi currency system ounds great but it has its own flaws.
Like if you got stagnation on one pair and than on another :)
Or you got them on mutliple pairs simultaneously, adding each others drawdown to horrendous values. 😉
That is a vaild question. I already taken this in the consideration. Correlation between pair should also consider when trading on multicurrency strategy. For example USDCAD & EURUSD have common currency USD so any strategy may have 50% correlation. So I reduced the risk by 50% when I will deploy any strategy. But in case of EURCAD and AUDUSD I will not reduce any risk as these pairs are uncorrelated to each other.
This is why trading is not easy you have to consider multiple things when trading.
Sounds again logical. But I have seen uncorrelated pairs producing negative results in parallel for the same strategy more than often. All these theoretical aspects sound smart, but trust me - market is smarter.
It is the same thing like analyzing market sessions, where 'usually' the asian session got the lowest range on average and all these night scalpers seemed to be the holy grail. Nowadays you have crazy moves during asian session more than often while trading during London session is mostly calm in comparison.
You are trying to get a peace of mind situation with these theoretical preparations. But it is no 'advantage'. Sorry.
I live trading these strategies since 2017 in forex with positive result. There is always some kind of correlation exist between different pairs. What I can control only risk on individual trades only.How strategies will be performed on future data there is no guarantee but only probability.
As a algo trader result of individual or few trades does not matter. The trading system decides which trades to make, regardless of current conditions.
The market will trade through it’s path of least resistance .
