Your system put you in a EURCHF trade despite telling you there is no EURCHF opportunity.
Of course only total amateurs would do such a thing.
Hmmm...what we've got here is failure to communicate. Some men you just can't reach:
A short trading signal on currency A/B followed (later) by a short signal on currency B/C does not mean you should close trade A/B and B/C and go short A/C.
Sure, you are now basically short A/C, so what?
You should know that by now. If not don't worry, the market will teach you that in due time.
