Asides from the usual regulation and trading conditions. i would also suggest checking their forex account types and what strategy do they allow so you know if that broker will fit with your trading plan or not.
Aximtrade also has a commission cost of $3/lot with min deposit of just $1. They are regulated by ASIC and also offer cent account if you want to start small with less risk than normal standard account.
the trading mentality is definitely a big part of a successful trader. Worrying about losses and having anxiety slow you down will just cost you more money.
It's a good idea to check out several brokers and make comparisons between them. Besides from regular license, spread is also important to check as low spread broker will help you save more on your trading cost therefor increase your profit per trade.
Pick a regulated broker with license from ASIC/FCA/Cysec so you know your money is save and use only for your trading. Anyone that offer guarantee profit is a scam brokers.
i dont think there's a definitive best broker out there cause there is broker that might be suitable to this trader's trading style and not other. Generally i guess just try to find one with regulation like ASIC,FCA and Cysec with low spreads.
a demo account is very important for beginners to practise their trading. When you feel confident then i would advise to switch to a live trading account.
yeah, it depends on others so if you are experienced and confident then yeah maybe copy trade isn't for you but if you are a beginner then copy trade is a good way for them to learn and maybe make some money off too.
