Service - Settings - Trading - "Show trades on the chart in real time".

Basically a great feature, only without the choice of timeframe to show, it's creepy on weeks.

What does timeframe have to do with it? The deal is shown (or not shown) on the timeframe. And the trade is displayed (or not displayed) by the SYMM.

Vladimir Karputov:

What does the Timeframe have to do with it? The trade is being executed according to the Symbol. And the trade is displayed (or not displayed) by the Symbol.

Handy thing, immediately shows errors in TA if there were deals. But on large timeframes icons, already obscure the candles.

I have not checked, but maybe this?

• CHART_SHOW_TRADE_LEVELS - property to display trade levels (levels of open positions, Stop Loss, Take Profit and pending orders) on the chart.

Good morning. Can you tell me how to open a link in a browser in MQL5? When I click on the button, it needs to open browser and click on the link. The code below gives out errors.

#import "shell32.dll"
   int ShellExecuteW(int hWnd,int lpVerb, string lpFile,string lpParameters,int lpDirectory,int nCmdShow);
#import

 ShellExecuteW(NULL, "Open", "explorer.exe", "\"https://mql5.com\"", NULL, 1);

Check theShellExecuteW parameters

in the function prototype, the 2nd parameter has the INT type, and you are passing the string....

Added

It should be like this in the prototype

HINSTANCE ShellExecuteW(
  HWND    hwnd,
  LPCWSTR lpOperation,
  LPCWSTR lpFile,
  LPCWSTR lpParameters,
  LPCWSTR lpDirectory,
  INT     nShowCmd
);

So your prototype is not described correctly
