How to choose a good broker? What brokers do you trade with?
You can trade with any broker you want.
But results can differ because of trading conditions (spread, commission, slippages, etc.) and different quotes (yep, even on the same instrument).
To choose the cheapest broker with MT4 you can use free TradingCost EA.
To choose a broker with MT5 you should compare trading costs yourself.
I can recommend a few brokers I trade with and make better conditions (commission discount, lower spread, etc) for those who will register using my IB-links -- https://communitypowerea.com/brokers/
