hi everybady, I encountered a problem, I was doing optimization, the optimization of the parameters out, and then re-set period of time once and optimize the same outcome and optimization of the results are not the same, you have been such a situation?
In the first picture,For example, I now do a history of EA optimization time is 2011/6/17 ~ 2011/10/17
2 pictures, I chose the best parameters in this group
Image 3, when I put a good optimization parameters, the test once again historical information, at the same time
4 pictures, test out and optimize its outcome is completely different, why is there such a big difference?
And optimize the results do not like the result of optimization is profitable 61.34 yuan, Total Trades: 79, Profit Factor 1.07, Expected Payoff: 0.78, using the optimized parameters back to the measured result is Trades: 22, Profit Factor 0.62, Expected Payoff: -6.85, why is there such a big difference? I also encountered another problem, good parameter to adjust a few days ago, in a few days once again test the same time, the result is completely different, some people come across this problem?
