If you have struggles with trade management, take a look at this video where I cover off some high level ideas that you should consider and then provide a brief overview of how I currently manage trades.
I cover three things that are important, firstly the type of trade you are taking (e.g. scalp, spot, swing), whether you like to take profit proactively, or trail your stop, and how your personal emotions impact your trading.
If you can work and settle on these, you should go a long way with your trading.
I look forward to providing many more trade management videos in the future.
