there are many causes of failure in trading not to understand the market, not to choose the right currency pair as a market trend, not to make a good strategy, not the right plan, greed to take more profits, not having control over their emotions. and Traders fail in this market to trade profitably because I think when new traders join this market they want to get the largest amount of money in one day without gathering knowledge about this market and for this reason traders give big losses with more trust!
