There is no ideal! I just watch people who write, so to speak, for general outlook. Sometimes I find some tricks I may learn from others. Sometimes I see that the code is not readable at all. Like tarasBY's, for example. No matter how hard I try, it cannot be read. I can read it in clear segments and then bam! I can't understand anything further. And so in many places.
I'm a friend who asked me to decompile, and it's easier to understand there than tarasBY's codes. Maybe it's kind of normal, but I doubt that many downloaders will understand them. Who is too clever to understand them, they will not download... Then the question arises why post them there :)
I measure my time according to Greenwich Mean Time.
I'm asleep now. Good night.
What do they say in Catalonia?
Not at all
Yes, it's the ratio of two natural logarithms. Now look at the formula from "Substitution of the base of the logarithm". So the result is that this expression
is equivalent to the decimal logarithm for bd_LOTSTEP. In MQL there is no separate function for the decimal logarithm, so this conversion is used.
This is what I was saying. The code of my language... I think either the programmer is not afraid of mathematics or it's a kind of protection from code reading (just kidding). I don't know, my personal opinion is that mathematics simplifies the algorithm just like switch...case instead of if.

used two indicators

Price channel.mq4
2)https://www.mql5.com/ru/code/8318

please help, why 1 shows and the other does not want?

There is one flaw in that code. Here, taken out of context:
The whole point is that the expression
Hence the lot value is rounded to one decimal place.
Read on, though, maybe it will help.

I just don't need lines on the chart, I just need two numbers (one from each of these spirit indicators).
