I really have not tried this strategy, but I read it, that some brokers also have positive exchange rate differences (all pairs except some) and traders are open to this pair, which has positive trades and wins even if the price does not change. To prevent the loss of prizes fluctuating for a while, they will change pairs that are moving at the same time as positive exchange partners. and as I see it I personally believe that book profits from swaps are really not worth it, because we will only get very small profits. When we enter this business, of course it's because we want to make a lot of profit. So, I think we need to trade with manual trading and with a good strategy, not just using swaps
