how do you read the last line of the textfile?

I can't figure out how to read backwards.

 

Hello, could you please tell me what I need to change in the script to make it work under build 765 MT4? It worked on earlier builds but not on this one. Taken from here https://www.mql5.com/ru/code/9507.

Hello, pros. I am struggling with the spread. Some solution: I have two zeroed one-dimensional arrays that are gradually filled with price values at each tick - Ask and Bid. How can I find the element with the maximum index and which is not equal to zero?

And instead of zeroing the array, use ArrayFree.
 
Can you give me a hint? What do I have to do to make it change in the navigator after compiling the EA. I change EA, compile it, and navigator gets the old version.

What if I save it under a different name? Well, add a number or something.
 
Please suggest a function that returns the number of digits after the decimal point. 15 minutes of browsing through the documentation, I know it exists, but I can't find it.

The problem is that normalizeDouble sometimes outputs 1.23499999999999999 or 1.234500000000001 and stoploops or profits are not working as the program monitors. I need to know how many digits after the decimal point a number so I can manually rewrite the number if it is larger than the digits variable.At first I found a quick way out - doubleToString and back stringToDouble. but while testing there were moments when even after that there was inaccuracy. now if I don't find a solution I will have to make a function that will check if bit and lot values are different for a certain part of a tick. if less than one sixth it means they are equal.

Somewhere in the documentation there was a warning that you should not directly compare numbers of double type and compare their difference with zero or a valid value.
