No words can describe the depth of your frustrations, disappointments and hopelessness. You have invested a great deal of money, time and efforts (no one would question your commitments) and yet the results has been far below your expectations. I believed you tried your best and probably you need to take a break (shut off computer, shut off FSB, etc) to clear your mind.
You have a number of choices:
1. Give it up and consider all those time, money and efforts as total waste. That's life, we lose some, we win some. And learn to let go, otherwise this experience will always haunt you as a "failure" or leaving you a deep sense of regrets (for taking this path).
2. Change the way you work. Same inputs = Same outputs. So it's not a question of trying harder, it's the question of what to try/experiment on. If you keep trying the same inputs (methods, workflow etc) you are going to get same output/outcome/failure.
As I've always said, there is 2 path of searching for profitable EA
1) Data mining
2) Theoretical based search (input your theory rules and keep fine tuning it) - This is my personal preference.
The truth is either one of these methods require lots of efforts (otherwise I won't be here still, I would be enjoying a luxurious lifestyle, letting my EA earn for me tons of money). Both methods require tremendous efforts to "search" for a successful workflow. It requires lots of experimentation, lots of thinking through what works, what doesn't and then fine tune the whole work processes.
And because it requires so much efforts (of overcoming failures after failures), few would want to openly share their "trade secret" just to anyone). If you have succeeded to climbed to the mountain top, would you share your glory with a stranger at the mountain base (who didn't participated nor supported you throughout your whole difficult journey and just want a pie of your success without paying the price of your sacrifice?).
Lastly, I "stumbled" upon FSB because I loss quite an amount of money in trading (as a newbie, many years ago) and I was at a cross road, 1) give up because I have already lose so much money or 2) count these loses as "tuition fees" to teach me the hard lesson of trading and make up my mind to overcome it by learn how to trade and this is the reason why I prefer to use the 2nd method (theoretical based) search for profitable EA via FSB.
So after so many years of trials and errors, I've developed a successful workflow for myself. The quest for me now is not about searching for profitable EA, my quest now is to improve my EA so that it is more stable and robust (win overall consistently).
Likewise, you are now at a cross road (whereby all FSB users will faced one day) and only you can decide what to do next. Give up or search for a better method (though you wish someone would just hand you their success workflow, who wouldn't wish that, I was wishing for that too but no one show me the ropes, so I ended up figuring it myself).
Lastly, Forex is really a tough game, to be honest, without FSB (or any other tools to assist you), it only going to be tougher.
And Popov is always trying his best to keep improving his software so as to make our search "easier and easier" (but that doesn't mean it's going to be easy peasy, though in the past, when I 1st started out, I was a dreamer, thinking it's going to be easy peasy, how naive and ignorant I was). And once I've found my workflow, yes, developing thousands of profitable EA is "easy" cos I've already done all the hard work of developing a successful workflow to churn out repeatable success. My next challenge is, to search for a "stablizer" to remove false signal effectively so as to cut down loses and improve the overall performance. Now I can see the glimpse of my success, I am glad I didn't give up (though many times I feel like pulling my hair after so many failed experimentation).
So likewise, I don't know which is better for you. Giving up, doesn't necessary mean a bad decision. It's about channeling our energy to where we think it's worthwhile. If you think you don't have time or aptitude for forex, it may be wise to give up. But if you enjoy the mental game of figuring things out, you may then be game for it.
PS: Stay tune, Popov may come up with a new feature in April (hopefully he doesn't get side track by other things) - "optmizing" either or both combinations parameters which I believe will improve our search further. Choosing the wrong combination is one of the key possible reason for my past failures.
