Keeping honest, detailed, and meticulous records of your trades is the only way to grow, and the best way to do this is by keeping a detailed trading journal. Van Tharp talks about this in his book Trade Your Way to Financial Freedom along with other ideas on trading for a living.
If you’re not into keeping hand written journals and don’t quite get the whole excel coding thing another option are these Trading Spreadsheets. There are various options to choose from for stocks forex, futures, and options you’ll be able to find something that suits your needs.
