I only use EA's of my own design for trading as I know my manual trading skills are "crap" yet I've been honing them for more than 20 years!
Target 5% to 10% per week, not greedy!

The profile pic shows me straight after my first glider solo flight, note the fear on my face, this was taken a few years ago, I learned to fly properly over the subsequent 10 years and found it to be a very enjoyable hobby.
