Hello programmers,

I have this EA that places stop orders above and below current price. What I need is an EA that will place limit orders instead of stop orders above and below current price. Can you change this EA to do just that while keeping all of the parameters the same?

Thanks in advance,
Paul

If you drop the basic moving average (included as indicator in MT4) on another indicator, it is possible to calculate the MA of the indicator, but how do you change a custom indicator in such a way that it's possible to drop it on another indicator?

Hi,

I'm wanting to run a piece of code only when a new bar is created (on bar open).

Anyone have a code snippet for something like this?

Cheers

Hola
I'm teaching mql.
I read Usage of Technical Indicators - Simple Programs in MQL4 - MQL4 Tutorial, but i don't find something like
Is it possible to color a single bar?Exemple during test your EA u can color the entry bar...
On metatrader i don't see any watch system, like to see the field of my variabile array there is in all C compilator
I wanto to to do this stupid system:
When price broke and close up the trend evelope (look the pic wich yellow cirlce) i open an alert and color a breakbar.
But my problem is that this that i read only the trend up indicator and not during short period why??

Code:

double maxprec= iHigh(NULL, PERIOD_M5,1);
   double minprec=iLow(NULL, PERIOD_M5,1);
   double chiusura2 = iClose(NULL,PERIOD_M15 ,2);
   double chiusura = iClose(NULL,PERIOD_M15 ,1);
   double chiu2 = iClose(NULL,PERIOD_M5 ,2);
   double chiu = iClose(NULL,PERIOD_M5 ,1);
   double apertura = iOpen(NULL,PERIOD_M15 ,0)
string rottura [3] = {" Nulla"," ROTTO"};


envelope15_1=iCustom(NULL, PERIOD_M15, "TrendEnvelopes_v1", 5,0,1);// trend envelope

if( chiusura2 > envelope15_2 && chiusura < envelope15_2 && apertura <= envelope15_2)  
      {
      rot=1;
      Alert ( " ha rotto SH M15");
      }
     else
      rot=0; 

Comment( ""\nBreak Enveolpe M 5= ", rottura[rot2],
           "\nBrerak Enveolpe M 15= ", rottura[rot]
           ); // Alert

is this the correct formula for calculating the value of a pip for the eur/chf cross:

(1/(eur/chf))*10*(eur/us)
a pip is .0001.

Correct formula above?

Use this code:

pipvalue=MarketInfo("EURCHF",MODE_TICKVALUE);

Hope this helps
