Do I understand correctly that after testing your strategy on new data it changed its behaviour completely?

the data is from the same place(mt4),just download time is different,one is workday,one is weekend.I don't know why the data is different.

Do you remember at what time you downloaded your data? Put that date into data horizon and your graph should be back.

not that problem,the strategy signal is totaly different,I wonder if it is the matter of spread on weekend

Re: is the data downloaded from mt4 on workdays different from weekends?

My broker changes spread on the weekend so the results are always a bit different.

My 'secret' goal is to push EA Studio until I can net 3000 pips per day....

I guess you will have to wait and see.....

It could be that the new bar data available on Monday will destroy your strategy.

I think he means because your strategy can not predict the future.

With regards to the downloaded data -- historical data doesn't change, right?  It could be a horrific error on the part of your broker, but that is unlikely.

More likely you are mixing time frames, symbols or data horizons and that is why the graphs look different than before.

The downloaded data (in *.csv or *.json format) is a text file -- so, you can view it in any text editor.  Better yet, there are many file comparison tools available for free or little cost on the Internet.  Why not do a file comparison between the two data files to confirm whether or not they really are different?  And if they are different, the file comparison will show you why and explain the mystery.
