Probably the most important tip I can give you is to accept the fact that some trades are just going to lose. There is nothing you can do about that. Every trader has losing trades. It is part of the forex game, forex is a game, there are buyers and sellers, and our job is to pick the right side. We can't always do it, but if we enter trades with at least 3 strong technical & fundamental reasons, then we give ourselves the best chance to succeed in the long run.
Many traders enter into a tailspin of emotional trading and losing money after they hit a string of winners. The reason this happens is because they feel confident and euphoric and forget about the real danger of the market and that ANY TRADE CAN LOSE. The key to remember here is that trading is a long-term game of probabilities, if you have a high-probability trading edge, you will eventually make money over the long-term assuming you follow your trading edge with discipline. But, even if your edge is 70% successful over time, you could still hit 30 losing trades in a row out of 100….so keep this fact in mind and always remember you never know WHICH trade will be a loser and WHICH will be a winner.
