Hello, I'm writingthe close prices of othercurrencies (in different colours) and the last barin the indicator buffer.As a result, I start the indicator - everything is correct. Then I start writing new bars. If I switch timeframes back and forth, the chart is nice, but I get horrible bars. How do I fix it? The EA goes crazy :)
price[i] = ((iClose(name, 0, i))/MarketInfo(name, MODE_POINT))/(1/MarketInfo(name, MODE_TICKVALUE))

Thank you.

How about if you want to know the crossing point when there are no bars yet, i.e. a date in the future.

you can calculate "in how many bars there will be an intersection" (just school geometry)

But the date can only be approximated by this, as the bars are formed only when the market is open, i.e. they are different for each instrument.

Simplified, if you know the calendar in advance:

  • add 24 hours to the current day, if it turns out to be Saturday/Sunday you skip it, if it's a general calendar holiday you skip it, if it's a bank holiday you skip it.
  • For W1 and higher you have to take into account that the weekly bar starts from Saturday to Sunday, M1 - as according to the calendar
  • for less than a day it is necessary to consider the market opening/closing time and the work schedule of your DC
  • at a change of dates (in the morning, at the first ticks) you have to repeat all previous calculations

that is so messy, that MT has a big problem with it :-)

 
I've been learning to write MQL4 Expert Advisors for about three weeks now! I wrote a compiled EA, no errors or warnings and everything seems fine. I found a big BUT it doesn't want to work . Maybe I can ask here where I made a mistake and what I did wrong. If someone tells me what to do, let me know. I am afraid this is my first time here and how to do it. Although I see how.
 

Hello!

Can you tell me which functions (user functions, special functions, standard functions) are used to communicate between terminals? Example:[product name deleted by moderator](copyer of deals for MetaTrader 4 terminal, copies (synchronizes, duplicates) trades from any accounts). And why does it not depend on ticks?

Functions of work with files, standard. It does not depend on ticks, because it works in a timer.
 

Is there an alternative to converting int to double for mathematical operations?

int NOL_Sell=1; //по факту счетчик - поэтому в double сразу нельзя
int N_Sell=2;   //по факту счетчик - поэтому в double сразу нельзя

double ProcTotalSell=StrToDouble(IntegerToString(NOL_Sell))/StrToDouble(IntegerToString(N_Sell))*100.0;
