Hi Laila,
I began as a manual trader as well, but as Popov once said in a post on the main forum for FSB “This is a different way to trade”. When I first started using the software I rushed into throwing EA’s live without really testing them on demo first. Now i know what to look for in order to do that, but when i started i blew an account just as fast as i funded it. OOS is something I pay Very close attention to, and I keep a little bit of data in my back pocket to truly verify the OOS in EA Studio. I’m currently working on learning FSB so you’ll see me asking a lot of questions in the FSB thread as well. To make that profit I’ve also had to endure two major drawdowns with my errors (i started a thread on this). I rushed strategies onto the live account at full demo size and a single loss on two occasions (the last one was a legit accident due to me being half asleep) put me in a 50% dd the first time, and the second was about 3 weeks ago and it took out all my previous gains and then some. Luckily last week was a REALLY good trading week and i made it all back with some EA’s i had put live on GJ and EU.
