Create and sell.

But first, study the articleWhat tests must a trading robot pass before it can be published in the Marketplace?

mql5. How can I programmatically find out the limits of the interval in which the test is running?

From time to time I see this kind of problem with the standard bollinger on a VPS:

And these are really crooked values:

From another machine logged in, the same standard BB is shown correctly. Maybe the reason is in the build. On VPS 2280 and on the other machine 2286.

Can I create dynamic classes with a name?

Class * bomba[];

for (int g = 0; g < sym_total; g++)

{
bomba[SymbolName(g, true)];
}

You can't. Or try this.

What is the analogue in MQL5?

If you don't want to bother, write it like this:

#define  Time(n)   iTime(NULL,0,n)
#define  Open(n)   iOpen(NULL,0,n)
#define  High(n)   iHigh(NULL,0,n)
#define  Low(n)    iLow(NULL,0,n)
#define  Close(n)  iClose(NULL,0,n)

it will work, but it is better to check for errors - in MT5 sometimes TFs are not available when called

In an indicator or in an EA?

If in an indicator, it broadcasts all the necessary data at once:

//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {

If in the Expert Advisor, then there is more choice:
