Rule prohibiting currencies with the same quote from being traded.

[OntradingX]

Does anyone have an example of how to create a condition so that it is not possible to trade currencies with the same quote:

For example:
EURUSD
GBPUSD
AUDUSD
XAUUSD
USDJPY true to negociation

I'm trying to understand what would be the correct logic to generate this block and avoid having parities with the same quotation with open orders.
Would anyone have any ideas?

Why would you want something like that exactly? Just curious.

@l-andorrà
According to my management, I list a maximum of currencies, indices, metals or cryptos that I can have open and working simultaneously.
Example:
Coins with 1000 usd balance my strategy allows only 3 to be traded simultaneously, but they can open the grid normally, as my balance increases this amount increases, as my balance drops, this amount drops.

But are those 3 trades open in the same or different symbols? Can for example be 2 trades on one symbols and the third one on another, for example?

@l-andorrà
They can only be opened in different symbols.
If I already have a trade opened with the EURUSD currency then I already consider that I have the USD quote open and I ignore all other attempts to open a trade with currencies that have a USD ending, for example GBPUSD,XAUUSD,AUDUSD all others that have quotes other than USD can open.
