I don't often look for arrow codes, but they are incredibly hard to find in the help!

It's a table with asterisks, circles, etc.

And the search returns anything but the right one!

Didn't notice that the KB version is old. Unfortunately there is no way to update. The KB machine gives this

MQL4\Include\fxsaber\HistoryTicks\ArrayResize.mqh(110,14) : error 165: 'ArrayResize_Real' - function already defined and has body
MQL4\Include\fxsaber\HistoryTicks\ArrayResize.mqh(172,14) : error 165: 'ArrayResize_Real' - function already defined and has body

MQL4\Include\fxsaber\HistoryTicks\ArrayResize.mqh(172,14) : error 165: 'ArrayResize_Real' - function already defined and has body

Everything compiles in ME without errors.

Why in line 3:

"sign mismatch" warning?

Datetime is supposed to be an unsigned number (8 bytes like ulong). Give me an example of a negative date.

probably because there is no separate timestamp type and datetime is also used to store the time difference

Can you tell me which event (if any) is generated in the tester when the Stop button is pressed?

Once again, help! I don't know how to get a better connection back, changing account doesn't help

When applyingChartSetSymbolPeriod inOnInit indicator during debugging on current data there is a strange thing - in OnTick() rates_total from old TF, and arrays of timeseries from new one:

datetime shift,arr[],arr2[];
void OnInit()
  {
 if (ChartPeriod()!=PERIOD_D1)
 {
     ChartSetSymbolPeriod(0,Symbol(),PERIOD_D1);
     CopyTime(Symbol(),PERIOD_D1,0,iBars(Symbol(),PERIOD_D1),arr);     
     ChartRedraw();
     Sleep(100);
  }  
 CopyTime(Symbol(),PERIOD_H1,0,iBars(Symbol(),PERIOD_H1),arr2); 
  }

Here we see Time[x] from Daytime, andrates_total from H1, while in the debugger window the chart's TF has changed to Daytime.

When you change timeframe, the indicator is completely recreated. I.e., the previous indicator handle is deleted and the new one is created.
But there is one "but". The previous indicator is still present for some time.

Isn't it the reason...

Yes, as I understood from my experiments, afterChartSetSymbolPeriodOnInit is completed and once (in debug mode at least) OnCalculate is executed (at this moment it is caught). I.e. it doesn't interfere with online operation.

The fact that data of different timeframes may arrive in OnCalculate is just a bug, I think.

Is this a flaw in ArraySwap?

void OnStart()
{
  int ArrayStatic[1];
  int ArrayDynamic[];
  
  ArrayResize(ArrayDynamic, ArraySize(ArrayStatic));
  
  Print(ArraySwap(ArrayStatic, ArrayDynamic)); // false
}
