metatrader as a simulator

i looked into simulators for mt4 but they were simply awful. even though what i found does not have orders it is far better than any other simulator. you simply want to not lie to yourself. that's it .


so take an expert that doesn't do nothing. then select visual mode and open prices only.start then pause the process. after that you will have control with f12 for each new bar.

i want to improve this kind of testing. i will learn mql in order to do this. but is it possible to put orders in visual mode with open prices only ?
i want the ability to place pending orders and to be activated imediately not when i clik f12. so this is my question to experienced programmers.
