But remember that when trading in real money, psychology will change, so stress and mistakes, will come into play.
In general, for a demo account there is no difference in the broker, the main thing is that specific broker has an option to open a demo account. But it’s very likely that you will continue trading with the broker you have started, so you can immediately choose a good broker, or you can try a demo from several brokers to check the difference. For the initial decision, you can use the comparison tables of Forex brokers.
