supertrend value

i made something approaching what i want but i cant understand the behaviour of this EA : its following supertrend switches sometimes, but it also reacts when the market reaches supertrend value...

here are the interresting lines of this code :

//green supertrend and previous value

double super0 = iCustom(NULL,0,"SuperTrend",0,1);
double prevsuper0 = iCustom(NULL,0,"SuperTrend",0,2);

//red supertrend and previous value

double super1 = iCustom(NULL,0,"SuperTrend",1,1);
double prevsuper1 = iCustom(NULL,0,"SuperTrend",1,2);

// turns to red

if ((super1!=2147483647) && (prevsuper1==2147483647)) Order=SIGNAL_CLOSEBUY;

if ((super1!=2147483647) && (prevsuper1==2147483647)) Order=SIGNAL_SELL;

//turns to green

if ((super0!=2147483647) && (prevsuper0==2147483647)) Order=SIGNAL_CLOSESELL;

if ((super0!=2147483647) && (prevsuper0==2147483647)) Order=SIGNAL_BUY;

i also wonder why this weird value of 2147483647 when the line isnt of the same color as the buffer, instead of a clean EMPTY_VALUE...

thanks again!!!

iCustom(NULL, 0, "SuperTrend",Periods,Multiplier,TimeFrame,0,1); //uptrend value

Code:

 
iCustom(NULL,0,"SuperTrend",10,3,0,1) //buffer 0 ie uptrend
 
iCustom(NULL,0,"SuperTrend",10,3,1,1) //buffer 1 ie downtrend

Code:

int start()
  {
//----
   
      ExtMapBuffer1[1] = iCustom(NULL, 0, "SuperTrend",Periods,Multiplier,TimeFrame,0,1);  //uptrend value
 
      ExtMapBuffer1[2] = iCustom(NULL, 0, "SuperTrend",Periods,Multiplier,TimeFrame,1,1);  //downtrend value
      
      if(Bid <= ExtMapBuffer1[1]) 
      {
         TrendDirection = "Up!";
      }
      if(Bid >= ExtMapBuffer1[2]) 
      {
         TrendDirection = "Down!";
      }
   
      Comment("UpTrend: ", ExtMapBuffer1[1], "n", "DownTrend: ", ExtMapBuffer2[2], "n", "Trade Direction: ", TrendDirection);
   
//----
   return(0);
  }

We are our own best indicator.

I have put the following for a call to the indicator, would this be correct to get the current price? It only works on the output of the bar I am asking (which is fine) I believe and does this seem right?

I added the Timeframe option in the indicator so I can switch through the timeframes...

I think I got it! 

I changed to the following and it is outputting fine!

We are our own best indicator.

"built in" indicators

iCustom() is used for indicator that are not "built in" indicators
If the indicator is a "built in" then you do not need iCustom(). Here is a list of "built in" indicators :

• iAC
• iAD
• iAlligator
• iADX
• iATR
• iAO
• iBearsPower
• iBands
• iBandsOnArray
• iBullsPower
• iCCI
• iCCIOnArray
• iCustom
• iDeMarker
• iEnvelopes
• iEnvelopesOnArray
• iForce
• iFractals
• iGator
• iIchimoku
• iBWMFI
• iMomentum
• iMomentumOnArray
• iMFI
• iMA
• iMAOnArray
• iOsMA
• iMACD
• iOBV
• iSAR
• iRSI
• iRSIOnArray
• iRVI
• iStdDev
• iStdDevOnArray
• iStochastic
• iWPR

So, if you are not going to use one of the above, you are going to have to use iCustom() for what you described

i have created my EA - ASCTrend.mq4

i have created my EA - ASCTrend.mq4 with MQ4 builder, which uses asctrend signal with ICustom function. it can open a BUY trade when UP signal, and SELL when DOWN.
i want to add to my EA some filter - with backtesting in some pairs, its look good fo filter with BBands ind, bud i dont know how to add this filter in my EA - something like that I think, but have no luck.

double Buy1_1 = iCustom(Symbol(),0,"PerkyAsctrend1",0,1);
double Buy2_1 = iCustom(NULL, 0, "BBands_Stop_v1", 4, 0, Current + 1);
double Buy2_2 = 1;

double Sell1_1 = iCustom(Symbol(),0,"PerkyAsctrend1",1,1);
double Sell2_1 = iCustom(NULL, 0, "BBands_Stop_v1", 5, 0, Current + 1);
double Sell2_2 = 1;

if (Buy1_1 && Buy2_1 > Buy2_2) Order = SIGNAL_BUY;

if (Sell1_1 && Sell2_1 > Sell2_2) Order = SIGNAL_SELL;

iCustom Question

I have an indicator which compares several values. I wish to bring those values into my EA. So far, what I've found, of the use of iCustom function is; calling the name of the indicator and comparing two different time periods of the same MA. How would I use iCustom to compare two different values of the same indicator.

For example:

Let's say that I have an MA of the average of the High and Low for a 15 min Period, and a MA of Close Price over 13 Periods, in the same Indicator. Let's say that I want to place a Buy, in my EA, when the MA of the Close Price crosses under the MA of the average of High/ Low, in the Indicator.


How would I utilize the iCustom Function to capture a state which occurs between two different MAs in the same Indicator?

 You just read the different indicators in your EA using icustom and do a compare

val1 = iCustom(NULL, 0,"sar_filter_alert",5,9,3,3,1,1,0.02,0.2,0,0);
val2 = iCustom(NULL, 0,"AsciiTrade",10,20,5,0,0);

Then if(val1 > val2 etc

or if you want to compare 2 values in the same indicator, change the values in the second read

val1 = iCustom(NULL, 0,"sar_filter_alert",5,9,3,3,1,1,0,0);
val2 = iCustom(NULL, 0,"sar_filter_alert",25,19,3,3,1,3,1,0);

Supertrend of a specific bar using iCustom

Hi homi,

Let�s assume we want to return the value of the indicator �Supertrend� of a specific bar using iCustom. 

If we want to get the returned value of the Supertrend first line:
We can write this price of code inside start() function:

Code:

double val=iCustom(NULL, 0, "SuperTrend",0,0,pos);

Here val will hold the returned value of Supertrend indicator(first line).

If you want the returned value of the second line, we can write:

Code:

double val=iCustom(NULL, 0, "SuperTrend",0,1,pos);

This is a program which will use Supertrend indicator using iCustom:

Code:

   int pos=Bars-counted_bars;
   
     
 
   while(pos>=0)
     {
         ExtMapBuffer1[pos] = iCustom(NULL, 0, "SuperTrend",0,0,pos);
         ExtMapBuffer2[pos] = iCustom(NULL, 0, "SuperTrend",0,1,pos);

         pos--;
     }
     
     
     
//----
   return(0);
  }
//+------------------------------------------------------------------+

==================================================
Use something like this in your EA:

Buff0=iCustom(NULL,0,"Indicator Name",0,0); //Top color of indicator
Buff0=iCustom(NULL,0,"Indicator Name",0,1); //1-Back

Buff1=iCustom(NULL,0,"Indicator Name",1,0); //Next to top color of indicator
Buff1=iCustom(NULL,0,"Indicator Name",1,1); //1-Back

Modify the variables in the indicator itself, and recompile the indicator which will update the buffers and the indicator on the graph!
===================================================

iCustom(NULL,0,"SuperTrend",10,3,0,1) //buffer 0 ie uptrend
 
iCustom(NULL,0,"SuperTrend",10,3,1,1) //buffer 1 ie downtrend

I-Customer Section for Expert Advisors

hello traders and programmers

i hope i�m right here to open this new thread , the idea is to post ONLY expert advisor code of ALL INDICATORS what you know for programming and test your own expert advisor .
SORRY FOR MY BAD ENGLISH.......

the form looks like a "FUNCTION" - my first examples :

Coding Zigzag

zigzag differs from most indicators in that for the large precentage of time it's value is 0, with only an occassional non-zero number..... that renders it almost unusable in the standard iCustom form.....

// ---> zig = iCustom(NULL,0,"ZigZag",15,5,3, 0, i);

to be useful you almost certainly will have to create an array to store all the "non-zero" numbers..... such as;

if(zig>0)
{
zag[n] = zig;
}

then you can do the common

if(zag[1] > zag[2]) // do this

else // or

if(zag[1] < zag[2]) // do that
