My first fxdreema EA

[danielsoy]

hi ppl.

I m not proud to present my first EA, based in bollinger bands n RSI levels.

It make some profit in gbp-usd 15M grid .

Look how:

Now I am struggling to learn how to use variables in my EAs.

I just want to count bullish n bearish candles, and make my EA or indicator, to play a sound, any time a
user defined amount of candles, has been reached.

A Variable is something that has Name and Value. Then when you refer to that Variable by it's Name, you can get it's Value. That Value can also be modified. This can happen everywhere in the EA, because Variables are global. There are different ways to get and modify them and I tried to sumarize them here in this example: https://fxdreema.com/demo/mt4-variables

Ok admin, thanks 4 that.

Guess that bull/bear in a row blocks can make the job in an easier way.

Will see how it works...

Is working pretty well using bulls/bears in a row blocks to count the amount of candles.

Was wondering if is there some block that can maximize a window, or i must make it through mt4 editor,
adding some code, inside blink the chart block 4 example.

As this video shows, I use my amount of candles counter EA, in a lot of windows at the same time, and any time some chart
reaches my target condition, I maximize that window by hand, clicking over Maximize button on the chart that is blinking red or green.

What i need is to maximize that blinking window automagically.

I can't find minimize/maximize options in MQL4 here - https://docs.mql4.com/chart_operations or here https://docs.mql4.com/constants/chartco ... ty_integer

Should be public now, in case is not, please search the video by its name, its the first hit.

**FXdreema: blink the chart block **

So there is not a way to resize windows in mt4 ?

[danielsoy]

Have found 3 chart properties related to the size of the windows I guess...

CHART_WIDTH_IN_BARS

CHART_WIDTH_IN_PIXELS

CHART_HEIGHT_IN_PIXELS

CHART_WIDTH_IN_BARS and CHART_WIDTH_IN_PIXELS are read only. CHART_HEIGHT_IN_PIXELS is not, but It appears to be woking only on indicator subwindows.
Open new chart, add some oscillator and play with this EA:

int subWindow = 1; // 0 is the main window, 1 is the first subwindow and so on...
int setpx = 20; // initial height

void OnInit() {
   ChartSetInteger(0, CHART_HEIGHT_IN_PIXELS, subWindow, setpx);
   EventSetMillisecondTimer(5);
}

void OnTimer() {

   if (setpx > 300) {EventKillTimer(); return;}
   
   ChartSetInteger(0, CHART_HEIGHT_IN_PIXELS, subWindow, setpx);
   
   Comment(
      "Main Chart Height: " + ChartGetInteger(0, CHART_HEIGHT_IN_PIXELS, 0) + " px\n" +
      "Subwindow Height: " + ChartGetInteger(0, CHART_HEIGHT_IN_PIXELS, subWindow) + " px"
   );
   
   setpx++;
}

If you set subWindow to 0, nothing happens.
