Using oscillators

Hello I spent this week trading just 4 currencies . AUDJPY, NZDCHF,EURAUD, AND NZDCHF.
Other than euraud I went short, as my trade analysis I used divergence and the matrix indicator on Sunday to hi e a guide.
As it turns out 2 of the trades lost and the other two look like losing.

I’m just wondering why this is the case.
Thank you
