Thanks Mladen to your comment.

Programming like dashboard? No demand auto trading. Just for monitoring and alert.

Regrettably but that's decompiled too ;(

I have shed a message for u pak. .
Will u travel to Kuala Lumpur when we supply the flight accomodation for two 3 days?

Hello, can I ask a question?
It has been perplexed me for a long moment.
Thank you!

When doing back evaluation in Visual mode, instead of automatically proceeding, we can manually demone the pub by one by pressing F12 key.
What I need to do is that by pressing a single key, for example S key (the main code is 0x53), then F12 will soon be sent into MT4 five times.
The code is as below. The result is, even when in back evaluation, pressing S key will show bars just as F12 was entered, but only one, or two come out each moment!
I wonder why it doesn't show 5 pubs...
Do you have some good solutions?
Thank you in advance!

#import user32.dll
emptiness keybd_event(int bVk, int bScan, int dwFlags,int dwExtraInfo);
#import

#define KEYEVENTF_KEYUP 0x0002 //-- key is published (not pressed)

emptiness OnChartEvent(const int id, // Occasion identifier
const long lparam, // Occasion parameter of extended kind
const dual dparam, // Occasion parameter of dual kind
const series sparam) // Occasion parameter of series type

if (id == CHARTEVENT_KEYDOWN)

switch(int(lparam))

case 0x53: // 'S'
keybd_event(0x7B, 0, 0, 0); // F12 1th
keybd_event(0x7B, 0, KEYEVENTF_KEYUP , 0);

keybd_event(0x7B, 0, 0, 0); // F12 2nd
keybd_event(0x7B, 0, KEYEVENTF_KEYUP , 0);

keybd_event(0x7B, 0, 0, 0); // F12 3rd
keybd_event(0x7B, 0, KEYEVENTF_KEYUP , 0);

keybd_event(0x7B, 0, 0, 0); // F12 4th
keybd_event(0x7B, 0, KEYEVENTF_KEYUP , 0);

keybd_event(0x7B, 0, 0, 0); // F12 5th
keybd_event(0x7B, 0, KEYEVENTF_KEYUP , 0);
break;
default:
break;

What exactly does F12 do on the MT4?

Assuming you delegated a XYZ() function to F12 button.
Therefore when you press S, you must call XYZ() method 5x

Inserted Code #import user32.dll emptiness keybd_event(int bVk, int bScan, int dwFlags,int dwExtraInfo); int SendInput(int nInputs,int pInputs,int cbSize); string GetLastError(); #import #define KEYEVENTF_KEYUP 0x0002 //-- key is published (not pressed) emptiness OnChartEvent(const int id, // Event identifier const long lparam, // Event parameter of long kind const dual dparam, // Event parameter of dual kind const string sparam) // Event parameter of string kind if (id == CHARTEVENT_KEYDOWN) switch(int(lparam)) case 0x53: // 'S' keybd_event(0x41, 0, 0, 0); keybd_event(0x41, 0, KEYEVENTF_KEYUP , 0); keybd_event(0x41, 0, 0, 0); keybd_event(0x41, 0, KEYEVENTF_KEYUP , 0); keybd_event(0x41, 0, 0, 0); keybd_event(0x41, 0, KEYEVENTF_KEYUP , 0); keybd_event(0x41, 0, 0, 0); keybd_event(0x41, 0, KEYEVENTF_KEYUP , 0); keybd_event(0x41, 0, 0, 0); keybd_event(0x41, 0, KEYEVENTF_KEYUP , 0); split; case 0x08://Backspace Alert(Delete); split; case 0x41://'a' Print(A); break;
With the code over when you click on S it will call click print and A A 5x

Thanks for your fast response!

Gt;What does F12 perform on the MT4?
When doing back test manually, F12 moves the chart forward by 1 candlestick at one time.
The link under clarifies this.
Https://www.fxdayjob.com/manual-backtesting-in-mt4

gt;With the code above once you click S it'll call click A and print A 5x
However, this doesn't apply to F12. Pressing S key will reveal two pubs just one, at most three pubs come out at a time, maybe not 5x as I wrote yesterday!
Maybe this is the bug of MT4 back test??

The issue is most likely the MT4 does not allow OnChartEvent() running on the Backtest.
That mean it will not allow input from your peripheral i.e. mouse click or keyboard click through OnChartEvent()
