strategy tester mt4, is a automatic paus function possible?

I don't think there's a auto pause function for every tick. I'll recommend slowing the back-tester down. When in very slow mode, it almost doesn't move. You can then pause it manually if you want it to wait there. Then when done with your analysis you can un-pause it or move the speed bar forward to speed it up again.

Just to add to ubzen you can't run and then auto pause to a specific bar.... but you can use skip to to take you to the start of a specific day.... you can run to close to the specific bar, manually pause it and then if you press F12, it will advance 1 tick... (I wish you could go back a tick too but unfortunately not).

#include <WinUser32.mqh>
#import "user32.dll"
  int GetForegroundWindow();
#import

void doPauseTest(){
   int hmain;
   if (IsTesting() && IsVisualMode()){
      hmain = GetForegroundWindow();
      PostMessageA(hmain, WM_COMMAND, 0x57a, 0);
   }
}

Works only in visual mode. The other mode does not have the ability to be paused, the button is grayed.

Update for speed=32

( I'd also assume from the GetForegroundWindow() call that it only works if you leave MT4 as the active window. If, for example, you minimise MT4 in the expectation that it will pause itself, and switch to another app while MT4 is running the test, then I don't think that this will work. )

...Sure enough, it doesn't work if you try to do something else while MT4 is running the test.

Therefore, it's preferable to use the following:

#include <WinUser32.mqh>
#import "user32.dll"
  int GetAncestor(int, int);
#import

void doPauseTest(){
   int hmain;
   if (IsTesting() && IsVisualMode()){
      hmain = GetAncestor(WindowHandle(Symbol(), Period()), 2 /* GA_ROOT */);
      PostMessageA(hmain, WM_COMMAND, 0x57a, 0);
   }
}

There don't seem to be any issues in using WindowHandle() from a visual-mode backtest...
