Then you can't interrupt the calculation by event.
ok. look the other way then.
You can artificially parallelise - by placing a second indicator on the chart.
And by accessing GlobalVariableSetOnCondition from both.

I don't get it.
The second indicator is a signaler that sends events from ChartEvent to the main indicator as a custom one + changes the state of global variable for example by the time in ms.
In the main indicator you catch this event and start the calculation, + look at the global variable to make sure that it has the same ms time as the one you started the calculation with.
If the time in it has changed, then a new event has arrived - and you break your current calculation.
like this.

Or you can simply change the ms in the gp at each chart event, and only control it in the main indicator
in general - the second indicator will parallelize
Hello! A little help for a newbie. I can't seem to get a handle on the OnBookEvent event.
If you call this event from onTick() , everything works. If onTick() is empty, then nothing works. I don't understand anything, OnBookEvent is called when there is a change in the glass, i.e. it is a separate event handler, essentially the same as onTick() is called when a tick occurs. Why doesn't it work?
This is how it works. Well, how it works, it prints "Anything" when a tick occurs, not when there is a change in the cup. For example, the volume of bids has changed, at a certain price, the OnBookEvent handler for the change in the cup should be called , but it doesn't happen. If onTick() is left empty, it won't even print anything.
int OnInit()
{
if ! MarketBookAdd("RTS-6.16" )
{
Print("Error ",GetLastError() );
}
else
{
Print("Done");
}
void OnDeinit(const int reason)
{
MarketBookRelease("RTS-6.16");
}
void OnTick()
{
OnBookEvent(_Symbol);
}
void OnBookEvent(const string &symbol)
{
MqlBookInfo book[];
MarketBookGet("RTS-6.16", book);
if(ArraySize(book) == 0)
{
printf("Failed load market book price. Reason: " + (string)GetLastError());
return;
}
Print("Anything");
}

Or you can use the signaler to change ms in gp at every chart event, and only control it in the main indicator

Got it, thanks. Unfortunately, this solution will only work in an Expert Advisor (in which the calculation must be interrupted). It won't work in the indicator, because call of the indicator on the chart doesn't create a parallel chart queue, it joins not even a specific chart, but ALL the charts of this symbol.
How do I put the indicator as MQ5-resource instead of EX5-resource?
