I've spent about 7k hours building edges, and like them very much. Just having a little bit of trouble executing them.
Either code and automate your edge.
Or if that no possible have a written trading plan defining every edge you have in detail.
Then execute your plan flawlessly. If you cant do that easily then you dont have confidence in your edge.
Its easier if you have a winning streak, but you will be tested during a long losing streak.
If it was emotionally easy to trade a long term profitable system through a multi month drawdown without jumping the system or abandoning it.
Then we would all be rich already.
