If i had a back testing strategy that gave me 20% profit per year. Can i expect to achieve 20% profit when live trading?
Do any of you have any personal experience with this?
I will do 3 months demo testing soon. I will post the results so others can see how well back testing works. (I would rather do 6 months but i do not have the luxury of time)
If you automated it and stress tested it with softwrae like build alpha for example then yes but otherwise you will have to deal with the psychological aspect.
I think psychology is the most important thing if you are not automating a system. Finding a setup is easy, being indifferent to wins and losses as they come and go is difficult.
So is it possible? Depends on your mental fortitute to follow your plan every single day for years.
do you suggest this is holly gral? 
Backtesting even for 50 years will never tell you what’s going to happen in the future - it at best would give you a clue that history repeats itself. That’s all.
So to answer your question. No. There are NO guarantees, ever.
Well i have developed a mechanical system to make the decisions for me. Il have to see how i cope with the draw down periods.
I doubt it. Its just a simple mechanical system that gets 60% wins in back testing. That could make me a maximum of 50% profit per year. If it does work id expect more like 20% profit. The best result i got was on GBP/USD where it got 12% profit alone after a lot of optimization. Anyway i really dont know what to expect until i start demo trading. Who knows maybe i just happened to stumble onto a good one.
Thanks for the response. I thought it would be like this. Well im going to start demo trading with what ive got.
