Indicators: Change Timeframes with Hotkeys - page 2

New comment
 

Hi guys,


Even with the updated indicator, when im using it while EA is running its making they system very slow...


The EA im running is - PZ trade pad EA


The same scenario while im running another EA - Trade Manger 4 lite.

 

Hello, Thanks for the hotkey indicator its really helpful but there is a problem, when you draw any Horizontal or Vertical lines it will disappear if you change the timeframe. 

Please advice. 

Thank you.

Oi, como é que eu não posso usar o teclado numérico, número 1, 2, etc?

eu só posso usar o número 1,2 etc em cima do teclado principal

é certo acontecer assim?

obrigada

Hi!

You can make the following modification to the original code. (see image "Modification.png")

But you are not limited to this modification, you can use the key codes you prefer and thus choose the physical keyboard character you prefer to use as a shortcut in MT4. (see image "Key Codes.png")

God bless you!

Use the

Function with the respectively

ENUM_CHART_EVENT

ID

Description

CHARTEVENT_KEYDOWN

Keystrokes


Plese see: https://www.mql5.com/en/docs/constants/chartconstants/enum_chartevents

And scroll down for example.

In this case it succeeds to remove

in

Function.

See below


Thank you, I added a switch on `TAB` to swap in all open charts.

Your code
 
bool isFixed=ChartGetInteger(0,CHART_SHOW_PRICE_SCALE,true);
  if(!isFixed)
          {
          ChartSetInteger(0,CHART_SHOW_PRICE_SCALE,true);
          }
  else
          {
          ChartSetInteger(0,CHART_SHOW_PRICE_SCALE,false);
          }
  }
Simplified 
bool isFixed=ChartGetInteger(0,CHART_SHOW_PRICE_SCALE,true);
ChartSetInteger(0,CHART_SHOW_PRICE_SCALE,!isFixed);
