Point

double Point

The point size of the current instrument in the currency of the quote.
See also MarketInfo().

Example:

The context was that if you attach this script to a currency other than GBPUSD, an algorithmic error occurs. Since Point is a point of the instrument in whose window the script was entered.

Hello. I wrote a multi-currency indicator based on WPR fast. But it doesn't update automatically and shows the last data 4 bars ago.

If you can, please fix the error.

extern int CountBars=3500;

//---- buffers

Why do you start the loop with int i=3?

[Константин Скворцов]

Roger >> :

And why does your loop start with int i=3?

Oh, man, that's right. That's why the data was given three bars ago. I took the framework from the multivalent fractal and didn't notice.

How to make it refresh the data?

[Alexander]

If you set it to zero, it will update immediately.

[Константин Скворцов]

Thank you, Roger!

Is it possible to limit in MT4 (or programmatically) the receiving of quotes not every tick, but, let's say, once a minute?

Is it possible to accept quotes during the Sleep() procedure?

You can not limit the quotes reception. But we can process quotes with a certain periodicity.

Sleep() does not prevent from quotes arrival, it's just that the Expert Advisor does not see them without updating of the market environment.

Sleep() does not prevent quotes from coming in, the Expert Advisor just does not see them without updating the market environment.

Thanks, understood to the best of my ability. I was only interested in terms of limiting incoming traffic.

If traffic is critical to you, the most effective way is to limit the number of characters used in the Market Watch window.
