Candlestick Coding Question

this resets the string, for bull / bear

after that it loops through the bull/bear function.
look for example at the bull(-function:


Inserted Code
     if(iClose(sym, mTF, 1) > iOpen(sym, mTF, 1)) {<------------ IF CONDITION MET
     PairString = PairString + ", "+sym; <------------------ THAT IS IT, CONDITION IS MET, SO ADD THE PAIRNAME TO THE STRING
     return(1); <------------------------------------ return(1)
     }//if(iClose(sym, mTF, 1) > iOpen(sym, mTF, 1)) {<----------- CONDITION NOT MET, return 0
     return(0);

Great comment FX!! THX.
If I will not reset that string
Inserted Code
PairString="BEAR PAIRS: ";//reset pairstring
code will use old information and will never rewrite that "string memory" with actual pairs?

Houston we have a problem

I have used your code and try to implement to my code but I am getting very strange alert....
Please can you tell me what I am doing wrong or better what I am missing in my code.
Looks to me that it can be something with this part in your code what I need to add but I am not sure
Inserted Code
    if((bear(symbol1) + bear(symbol2) + bear(symbol3) + bear(symbol4) + bear(symbol5)) >= minVolume)
    {  
     whatdir = "BEAR";
 ====>    if (lastdir!=1)
    {
 ====>     lastdir=1;
     if (GiveBearAlerts)
     doAlerts(PairString,SoundFileBear);

here is that strange alert and my code

of course, if you never reset the pairstring this happens

ok I have add also that

Inserted Code
PairString="BULL PAIRS: ";//reset pairstring
above this code
Inserted Code
if((bull(symbol1) + bull(symbol2) + bull(symbol3) + bull(symbol4) + bull(symbol5)) >= 2)
and looks that it is working
But I must say that I don't have any idea why this one line code solved this problem
FX it is possible to explain me in few words why this one line help?

Many thx

what about learning mql4 (at least the basics)?

FX I am trying
But it is not easy. I know that for you everything what I have asked here looks so easy and basic but for me it isn't and where to learn mql4 when not here?

where to learn mql4 when not here?
by taking indicators, scripts, ea and learn what the commands are doing (example for the alert-command: google -> site:mql4.com + alert() ) and so on, reading tutorials, etc.

Asking questions is also ok, as long as they are not about completely basic stuff which can be learned by simple googleing and trying.
Since I am just a mediocre coder I cannot offer private lessons, maybe somebody else will do it ...

OK.
Looks to me that reset string variable it's not working same way like reset int or double variable.
Because int and double variable I can reset always on end of "if" code. But string variable you are reset before "if" code start. Is there some easy explain why?

Thanks

yes. Reset before the if-loops make sense because I only want the pairstring holds either the BULL pairs or the BEAR pairs

Hi guys.

I worked on this code and have add next step.
My Q is if it is correct.

After first "if loops" when code is checking MinVolumeBull or Bear. How to save (best way if there is one) pairs which complete this first if loop step? Later I want use these to another if loop conditions.
I used this idea but looks to me to much complicated and maybe also not correct

THX

Inserted Code
                           if(MinVolume(symbol2) != 0) {NoDemandClose(symbol2);}
                           if(MinVolume(symbol3) != 0) {NoDemandClose(symbol3);}
                           if(MinVolume(symbol4) != 0) {NoDemandClose(symbol4);}
                           if(MinVolume(symbol5) != 0) {NoDemandClose(symbol5);}  
                      if((NoDemandClose(symbol2) + NoDemandClose(symbol3) + NoDemandClose(symbol4) + NoDemandClose(symbol5)) >= 1 )

Maybe for better understanding. How to save currency pairs from one "if" loop statement conditions and use it later in that code?

book.mql4.com ...
or google: mql4 + SEARCHTERM I DO NOT UNDERSTAND or mql4 + PHRASE WHAT I AM LOOKING FOR (for example: mql4 + how to count open trades).

doing it this way (and try+error/reading existing mql4-files) you can learn it.
