Vitalie Postolache:

Fibo levels with this object cannot be made in different styles and colours for each line. Draw separate lines if you want a rainbow.

Too bad(, thanks)
Vitalie Postolache andVitaly Muzichenko told me where to get the information! It was easy. The currency amount should have been divided by the point value. 600/MarketInfo(Symbol(),SYMBOL_POINT) Thank you.

It's the wrong decision. It's like adding thin and soft and expecting the output to be transparent.

The point value (tick) is not what you wrote (there is no such query as MarketInfo(Symbol(),SYMBOL_POINT) at all), but MarketInfo(Symbol(),MODE_TICKVALUE).

You should divide sum in currency by lots and tick value.

I don't know. It all shows and closes by this principle. Tried addingMODE_TICKVALUE and it shows the same thing. Ok, I'll replace it with your suggestion)
Hello, this topic is already muddled, but I'm a bit slow on the uptake and want to ask, how do I use the new bar function? What code and function is needed so that before opening a trade it will check - is it a new bar?

Hello again. Can you tell me how to change the code of a known programmer. At the moment this owl closes about one trade per second. Would like to change to close trades instantly as it crosses a certain profit regardless of positive and negative trades.

Rustam Bikbulatov:

Hello again. Can you tell me how to change the code of a known programmer. At the moment this owl closes about one trade per second. Would like to change to close trades instantly as it crosses a certain profit regardless of positive and negative trades.

MT4 doesn't know how to close all at once, only one at a time. Switch to MT5 and it will close simultaneously
Vitaly Muzichenko:
MT4 can't close all at once, only one at a time. Switch to MT5 and it closes all at once


Well it's natural that it closes one trade at a time) It's just that one trade is closed about once per second. It's a very long time.

I understand that when you close one trade it checks all the code to close the next one.

Try to comment out the line and let one function run

  if (pr<-TargetLoss || pr>TargetProfit) {
   // ClosePosFirstProfit(symbol, Operation, MagicNumber);
    ClosePositions(symbol, Operation, MagicNumber);
    if (DeleteOrders) DeleteOrders(symbol, Operation, MagicNumber);
