Artem(no offence)!

The FOREX people come to the Exchange topic, "put their foot up", then get off without proof!

What has pride got to do with it, if I'm wrong - I'm ready to admit it!

But from logical reasoning and my own experience

OnBookEvent() is faster and doesn't miss a single tick, not a single change in the glass!

Find a bug (if there is one) in my code.

From the logs of my code - everything is very clearly visible!

I'm not interested. I can see that there is no difference. But Andrei promised to show you how to do it better. But he made a condition to show you that is impossible for you to fulfil.

I don't care. I see that there is no difference. But Andrey has promised to show you the best way. However, he put an impossible condition to show you.

Okay.

But I'll say just a small remark.

The fact that OnTick() doesn't handle pending orders

2020.01.31 17:02:01.492 Ticks_test (GOLD-3.20,H1)       OnBookEvent: Pending order!

is a good reason to dump this function in the trash for stock trading.

Документация по MQL5: Константы, перечисления и структуры / Торговые константы / Свойства ордеров

Приказы на проведение торговых операций оформляются ордерами. Каждый ордер имеет множество свойств для чтения, информацию по ним можно получать с помощью функций Идентификатор позиции, который ставится на ордере при его исполнении. Каждый исполненный ордер порождает сделку, которая открывает новую или изменяет уже существующую позицию...

Any questions from newcomers Any rookie question, so [Archive!] Any rookie question,

Sergey Chalyshev 2020.01.31 16:30 #110

I would like to remind you that OnTick receives two independent threads, information and trade,COPY_TICKS_INFO and COPY_TICKS_ALL and undergoes preprocessing .

These threads are not synchronized with each other, so if you compare OnBookEvent with OnTick, you should takeTICKS_INFO.

By definition, OnBookEvent should be faster since it doesn't go through pre-processing.

The tests do not reliably determine who is faster, because we do not know the stock time of the tick.

Although, we have many times asked developers to ADD STOCK TIME! ! !

p.s. besides speed, tumblr also has advantages over OnTick,

as already stated, it is not possible to get better Bid and Ask prices in OnTick,

andOnTick doesn't get data from other symbols, it's useless for Expert Advisors analysing multiple symbols.
