It's all written in. It's all there at first, then it's gone.

What's in the logs?

Metaquotes-Demo, USD account, RTS-3.17.

TickValue gives wrong value - in roubles, not in account currency (USD).

FxPro-ECN. The symbols GOLD and GOLDEURO have the same TickValue. Although, obviously, they should be different in EURUSD times.

You have to understand that the "TickValue" concept is interpreted differently depending on the market and is interpreted either as a contract parameter or as some kind of calculated value.

1. If in the contract specification (see the appropriate dialog in the terminal), there is a value of the tick, then it is returned. For RTS-3.17 - everything is correct - in rubles, because the instrument is traded in rubles.

2. In other cases it is the calculated value.

Originally TickValue was needed not for what is shown in point 1. You need a normal functionality, which is already implemented, but not available.

Peculiarities of mql5 language, subtleties and tricks

MT5 has an internal hidden mechanism that knows how to convert any currency to account currency. In this case OrderCalcMargin 1000 NOK translates to the appropriate USD number and outputs it.

Please make this mechanism public. For example,

double CurrencyExchange( const string Currency ); // возвращает курс валюты Currency к валюте счета

These exchange rates are 100% available in the terminal, since OrderCalcMargin calculates them. Their work is especially noticeable on MetaQuotes-Demo USD accounts when you take FORTS symbols - their margin currency is in RUR.

This is especially relevant because of the TickValue chip/bug

Didn't check.

struct _global

Such structures cannot be copied by ArrayCopy due to the presence of an object of unknown size. And this is correct.

ArrayCopy does not generate a Warning/Error when arrays of this type are set as input.

And work is unbearable with constant rebooting of Windows...

Is ex not creating a new one, or is it failing to overwrite an existing one?

Try some utility to see which programs are holding the ex file and preventing it from being overwritten. Free Multi Commander for example has built-in tools for that.

It doesn't seem to be an ME problem.
