I'm looking for a script that closes all orders by lot size, all meaning all (and not choosing by magic number, low low, etc.), so all orders would be closed and could be filtered by lot size only.
So the usefulness of such filtration is obvious only to you. :)))

There must be some. Do a kodobase search with a script filter.
 

why trades are opened and closed at prices that do not exist.... how to fix this and how to improve modelling quality

At prices that do not exist... The price chart is based on Bid, and the Ask price is also involved when opening or closing trades.
 

Has anyone reworked the EA from the https://book.mql4.com/ru/samples/expert tutorial so that it opens and closes an unlimited number of orders? I can't get it to work. I can open several deals, but I cannot close them all at reversal. It closes one order and immediately opens the opposite one. I really need it. I have already learnt MQL4, but I am not familiar with arrays and functions of orders.

Excuse me, for those who are not very bright, where is this? on which resource and what to type into the search engine. or give me a link.

Sorry, for the not-so-smart, where is this? on what resource and what to type into the search engine. or give me a link straight away.

Not exactly by lot, but maybe you can adapt it

i.e. they are absolutely real and the test results may be considered correct? ...... how to view all prices

Yes, Ask prices are not visible, but they are :)
In the visualizer, you can press pause and select "Show Ask Line" in the chart properties and continue testing. The price chart in MT4 is normally plotted by Bid.

What should I add or change in the script to close all open orders for all pairs by lot size.
