Have you tried Tools-Database Purify to see if there are any obvious data flaws?

Subject: [amibroker] I need a data error detection formula

Hi,

When I tried to optimize my rules, I got many 99,XXX % profit.  I think this is probably due to error in the database, probably one or many bars.  I tried to detect them with a zigzag function, and then with other formulas, but it seems it is not that easy to do.  Anyone could suggest a good formula to detect those errors?

Thanks,

Louis
