I am backtesting an EAs that I have I used control points and tick mode. The tick mode has a horrible performance. Do you know why?
This is challenging me since the performance from the control points is very in line with my manual performance.
The MetaTrader 4 terminal replaced the third terminal and included a new compiled language MQL4
(Previous MQL-II was interpreted), as well as took an absolutely new
approach to testing. Now testing could be carried out in three modes:
Make sure M1 data is present. (Press F2, Download M1 data to history center)
The testing strategy of the MetaTrader 4 terminal used the price data of
the youngest available time frame for trading simulation. Therefore,
with the presence of the minute history, throughout the tested interval,
the test results are maximally close to the results obtained online.
