Concerning DatabaseBind:

DatabaseBind

"The function should be used when the SQL query contains parameterizable values "?" or "?N", where N stands for the parameter number (starting with one). The indexing of parameters in DatabaseBind() starts at zero."

Is this the way it was intended? In sqlite3_bind - these indexes correspond, while yours are offset.

Questions from Dummies

How do I know that TRADE_RETCODE_MARKET_CLOSED (market is closed) for a specified symbol without sending a trade order to the server?

If i know that the quotes go, but trade is forbidden for a few minutes after the opening of the trading session, how do i know if trading is allowed to go on request at any time without pounding the server with trade orders? for almost 8 years nothing new about this topic has appeared in the help, please correct me if i am wrong.

There are times when quotes go but trading is suspended for a few minutes after the opening of the trading session, how do I know if trading is allowed on request at any time without pounding the server with trade orders?

Similarly, if FORTS is "barred" and trading is suspended.

Take a look at the specification.


If it's filled in correctly, there's no problem.

not clear, so is there a solution or not?

 
Andrey Dik:

I don't understand, is there a solution or not?

It's not a solution, it's an extension of the question.

 
Alexey Viktorov:

Look at the specification.

unfortunately there are problems, the trading session is open and trading is prohibited "Market is closed". therefore - trading sessions cannot serve as a reliable guide. you need a direct way to know at any time on request "i want to trade. can i send trade orders right now?"

 
Alexey Viktorov:

Look at the specification.


If correctly filled in, there is no problem.

For FORTS it says 6:45-24:00, not 7:00-23:50. But that's fine.

But what about clearing, which can have different durations?

 

Good afternoon, gentlemen.

Totally can't figure out the execution of functions like TimeCurrent() or iTime.

1. When I print this function, it should show the number of seconds elapsed since 1970. Instead it just shows a nice-looking date in format yy.mm.dd hh:mm:ss. How can I know number of seconds?

2. I have written a simple script (it is shown below), but when I run it for the first time I get a total rubbish - the last bar open time could be few hours earlier than the real one, and today's last one-minute bar was open in 1970.If I re-run the same script after that the result is accurate enough, though M1 bar open time can be shifted. I have 2terminals installed andget the same result.

Has anyone encountered such a problem or it is just me?

Thank you all.

I don't know where to post this, so I'll post it here.

Previously, the link from the "AllPosts" profile, which sort of https://www.mql5.com/ru/users/traveller00/publications/all led to posts. It's been going to publications for hours now. So how do I view the posts now? Is it something broken or is it a feature now?
