Urain:

Then I see no reason not to introduce a direct read function without type conversion, ala

There's a similar example via structures in the stringo link.

On a related note, I was just about to ask about unions.

Speaking of which, I was just about to ask about the unions.

no. but bringing in the structures solves the problem.

sergeev:
struct __double { double v; }

struct __long { long v; }

__double a; __long b;

a.v=123.456;

b=a;

b.v=4638373815016729713;

not hard.

Ahhhh, got it, question cleared. Thanks for the magic kick :)

Can you please tell me what the error in log 2012.04.24 18:19:01 HistoryBase 'GBPUSD' 1 invalid bars removed means? This error message appears every time I change TF. And it does not occur on all pairs.

tested in new build OrderSendAsync

I'M SHOCKED! IT WORKS!

Well done, keep it up!

And management should organize a corporate party for employees on May holidays on this occasion.

)))) Cool. No words.

But not all of them are probably welcomed in such packs...

)))) That's cool. There are no words.

Just not everywhere will accept such batches with an embrace...

Keep in mind that there are and will be limits on the number of simultaneous applications in the execution queue from one account. Right now it's 16 applications if I'm not mistaken.

Asynchronous operations will neatly handle the "window of the number of allowable orders", waiting for part of the previous batch to be executed before sending the next batch. In addition, there will be protections against stupid/test flooding. As long as the number of allowed requests overflows, there will be an error.

The new asynchronous transactions method via OrderSendAsync solves the main problem - it allows you to do a dozen transactions instantly. This is a very powerful tool, and it should be used carefully and always with an eye to the possibility of bans by the server and broker.

I have an open position. Does MQL5 allow me to modify the magic number of such position?

There is no modification of the magic number. In what case would you need it?

No, as said above.

But you can assign each order within a position its own magic number, and the position will receive the magic number of the first order.
