maybe it depends on what strategy is used too bro, because I've seen a trading strategy that uses the entry of many positions even in several pairs simultaneously, but there are also those that only focus on one entry in one pair
I think the more entries there will be, the more I think about, especially if in several different pairs, I believe it makes the difficulty level higher, if I'm not used to trading like that, it certainly won't be able to produce the best decision for entries made.
I myself am more comfortable focusing on one position in one pair, because I don't have the capacity to analyze regularly to open open entries, from the management side, it is also easier to calculate with one entry every time I trade forex.
I prefer to force one entry to get the best results than making multiple entries which also makes them emotionally vulnerable, because trading conditions with multiple entries can trigger over trading, more vulnerable to over trading, of course.
