The most important thing in trading is to gain a lot of experience to manage the risk. So new traders should learn risk management before the actual trade. Most brokers like Eurotrader offer educational materials that cover risk management. This broker also offers no requotes in trade execution and many more.
Traders need a platform to analyze and trade in the online market which brokers offer to their traders. MT4 and MT5 are the most popular trading platform in the world. Most brokers offer the platform. My broker TP Global FX also offers both platforms. MT4 trading platform is best for forex trading and the MT5 platform is best for other trading products than forex.
