int Ret[3];

Ret[0]=NormalizeDouble((Ask-Bid)/Point,0); 
Print (Ret[0]," ",(Ask-Bid)/Point," ask=",Ask," bid=",Bid); 

it works like this

Thank you!

Thank you!

In general, it is time for MT developers to create a section in the documentation and explain in detail the problem and the need to use normalisation.

There is only a modest example without emphasis in the documentation for this situation:

int    i = 1 / 2.0;   // выражение приводится к типу double, затем приводится к целевому типу int, результат: 0

To FoxUA.

When Order 3 (Sell) is closed, that Order 1 (Buy) still semaphores that it was closed on Stop Loss and so 2 orders in a row are placed, because Total=1.

i.e. i look for a solution to this issue, i.e. what to replace total 1 to get rid of such an effect

Can you tell me if the script can open orders not only in the window of the chart to which it is attached, but also on other currency pairs, if it is properly prescribed on which other currency pairs you need to open?

No, what you highlighted will be returned from the current tool. Bids, asks, digits and so on should be requested with MarketInfo explicitly specifying the tool

It won't. You have to use the MarketInfo function https://docs.mql4.com/ru/common/MarketInfo.

there are examples of your problem on the page
