Sorry for the flooding, I'll ask you again.
Can you suggest a free open interest indicator? Thanks in advance!
You can't write codes that inattentively :)
Go to Comment("USDCADAsk = ",USDCADAsk); followed by USDCADAsk = DoubleToString(MarketInfo("USDCAD",MODE_ASK),usdcaddigits); USDCADAsk is declared as double and you put a string in it,
and then Digits.... again ^) and Point
You have to look for such errors yourself, no one will fix them for you as well as trade! The compiler generates 28 errors and you put the demo into trading. You may wish you were using real money but the market would have corrected you!
Whose Bid Ask is it ?
Correct
Turns out you didn't need to use additional variables and then you don't need normalisation, it should be like this.

Firstly, you yourself tried to display them on the screen to check, which led to errors, and secondly, normalization is desirable and the order setting price and TP, SL. If the price is not normalized, it can cause errors. This is the rule and we should not break it. See examples and analyse why this is the case and not the other way around, e.g. https://book. mql4.com/ru/samples/shared
Hello! If you don't mind telling me how to add say 23% to OrderOpenPrice? If you know that OrderOpenPrice is already 77%. I'm dividing by 77, multiplying by 23 and I get 7 points instead of 31. Here is a line of code if (MarketInfo-OrderOpenPrice()>OrderOpenPrice()/50*Percent*Point). This is a transfer to Breakeven, but not in points, but in percentage points. Thank you in advance!
I bought one hundred thousand euros at 50 rubles, then I add 23% to the purchase price.
For your case, you need to lay out the code in full. Although if you just want to bring it to 100%, divide by 0.77.
Thank you for your reply. Here's all the code

I didn't write it to reproach, just to let others see. Thank you for your time.
A functionally quite complete expert. What do you want to add to it?
Это перевод в безубыток, только не в пунктах, а в процентах
What percentage value do you want to translate the breakeven on?
And you will still need this value in pips to modify orders.
