Urain described the function above.

Get the bartime of the desired timeframe based on the date.

Can you tell me why I get different values when calculating lot sizes in different DCs?

For example: 1DC - available funds: 10000, min.lot 0.01 calculated 100% of available funds get lot size 79.37

2DC - free funds: 10000, min.lot 0.01 calculated 100% of available funds get the lot size 7.96.

What I do not take into account, why the lot size is different?

There are brokerage companies where 1 lot = 10000 units of the base currency (e.g. Insta). Refer to the specification of the contracts.

Number of signs?

Silent:
Number of characters?
What does the number of digits have to do with it? It's not even an order of magnitude difference. It's the difference of 0.23 lots. And the pair is exactly the same? And the opening price?

What's the call signs got to do with it. It's not even a question of an order of magnitude difference. It's the difference of 0.23 lots. And the pair is exactly the same? And the opening price?

This is called a mini or microreal.

Some dealers simply give fractional lots, others change the contract size, so a 0.01 lot in a regular account turns into 1 lot in a microreal account.

These are so-called cent accounts.

You can get the value like this:

`SymbolInfoDouble(_Symbol,SYMBOL_TRADE_CONTRACT_SIZE);`

Yes, you gave me a good hint!

Do I just keep doing this?

g_d_ContractSizeDiv = 100000/g_d_ContractSize;//Difference

and then multiply g_d_ContractSizeDiv by the lot size?

Can you tell me if there is a ready-to-use function for splitting by thousands, e.g.: from 1000000 to 1 000 000?

pusheax:
Do you know if there is a function that splits a number in thousands, like 1000000 to 1 000 000?

So I understand that you need a visual split, then you need to convert the number to string. And then do whatever you need to do with string.

The function you want is missing, but you can easily create it yourself using the StringSubstr() function.

String functions

That's sort of it:

```string FormatInteger(ulong val)
{
string temp=IntegerToString(val),res="";
int len=StringLen(temp);
int i=len-3;
while(i>=0)
{
res=" "+StringSubstr(temp,i,3)+res;
i-=3;
}
if(len%3!=0)res=" "+StringSubstr(temp,0,len%3)+res;
return(res);
}
void OnStart()
{
Print(FormatInteger(10000000));
}```

Thanks, I'll try to add it.
