Candlestick Coding Question

Hi guys.

I have one coding Q.

I am looking to code this idea.
For example I am checking EU/EA/EJ/EG where three of these pairs must have second candle bearish and next (first) bullish. How I can code this?
How my code can check all four (or more) pairs but give alert when min. three of these pairs have same conditions? For example candles conditions...

Thanks for help

ok. If I am understand your code correctly "int bull" function is giving me numerical value 1 or 0. If overall count is bigger than 3 in "int counted_bars" function it will trigger alert....
Am I right?

Another Q what I have is about this part of code:
int bull(string sym)
{
if(iClose(sym,0,2) < iOpen(sym,0,2) && iClose(sym,0,1) > iOpen(sym,0,1))

return(1);
return(0);
}

I can't find out how the code will know which number it must return. Because there are two return for one condition...

Can you explain me this?

btw, there are NOT 2 returns for 1 condition:
if (XYZ) return(1);
otherwise return(0);

FX I am not asking how this cpart is working
if(iClose(sym,0,2) < iOpen(sym,0,2) && iClose(sym,0,1) > iOpen(sym,0,1))

but how will code know which number (0 or 1) return. Because this is first time when I see two return function in one if statement.

I think you should learn to code, or at least the mql4 basics, syntax etc. ...

FX if I will know how to code I will not ask on this forum such a simple Q
I know that for you this Q is easy but for me is not I haven't see this solution with two return in one if statement therefore I am asking...

last try.
original:

Inserted Code
if(iClose(sym,0,2) < iOpen(sym,0,2) && iClose(sym,0,1) > iOpen(sym,0,1))
return(1);
return(0);

for better understanding we simplify it a bit:

Inserted Code
if (CONDITION)
return(1);
return(0);

this is the same as:
Inserted Code
if (CONDITION) return(1);
return(0);

because it does nothing else mean as:
Inserted Code
if (CONDITION) return(1);
if (NOT CONDITION) return(0);

OK. I don't know what I am doing wrong but something in my code must be wrong because I am not getting any lines.
Idea is that after two or more same conditions (candle formation and min volume) it will plot line. But no lines on 1M testing chart and I am testing it now several hours..
Can anybody help?

THX again

pls. look.
for testing purposes I set symbol1=symbol5 and did some other thingies (.e.g optional delete of the lines on exit and adding an screencomment which can be useful when testing/experimenting. further a sound will be played).

pls. see screenshot, it has drawn a green line (and played the sound).

note that if your broker uses symbolnames with suffixes, like EURUSDm or EURUSD- you will have to change your inputs also.

Amazing work FX!! THX.
I am slowly adding more pairs and testing.
If I will run all five pairs and more than 3 must have same conditions (>=3) How I can get info (in email or in comment) exactly which of these pairs met these conditions? Is there some function which will write me exact pairs?

For example I am checking in my code these:
extern string symbol1 = "EURUSDm";
extern string symbol2 = "EURAUDm";
extern string symbol3 = "EURJPYm";
extern string symbol4 = "EURGBPm";
extern string symbol5 = "GBPUSDm";

I get alert and now I must check all these pairs manually which exactly met my conditions because I don;t exactly know how many and which are in my alert. Only what I know is that they are 3 or more.

thx

pls. have a look, I have added an alert-function (not tested yet // edit: seems to work).
I think you can modify it to fit your needs.

Hm, I assume you want to build an EA from this indicator, e.g. buy all bull pairs and sell all bear pears on alert?

Nope FX.
I am looking for one pair which is most bearish or bullish. Therefore I must compare more pairs and pick one from that group.
I am looking to your latest code and also testing it but can't find where is code for that "pickup pairs" function.
Because now when I get alert I get only info that conditions are only in EU but nothing else.
My testing setting is:
all five symbols are active (EU/EA/EJ/EG/GU) and alert will run if two or more (>=2) have same conditions.
Therefore I was looking to get info in email and alert notification that EURUSD and min other one pair will be write in that alert but only EURUSD is displaying...

of course because look to that in the code:
Inserted Code
//FOR TESTING, set dymbol1 and symbol5 to the current chart symbol:
   symbol1=Symbol();
   symbol5=Symbol();

you could compare the currencies, eur usd cad, etc., see e.g. http://www.forexfactory.com/showthre...31#post7350231 or the css indicator by deltabron (see stevehopwoodforex.com for latest updates).

Great it is now showing all pairs where conditions are met.
I am trying to figure out now how you did that...

I only see that it is on this part of code

Inserted Code
   if((MinVolume(symbol1) + MinVolume(symbol2) + MinVolume(symbol3) + MinVolume(symbol4) + MinVolume(symbol5)) >= minVolume)
   {
 this  ===>    PairString="BULL PAIRS: ";//reset pairstring
    if((bull(symbol1) + bull(symbol2) + bull(symbol3) + bull(symbol4) + bull(symbol5)) >= minVolume )
    {
     whatdir = "BULL";
     if (lastdir!=2)
    { lastdir=2;
    if (GiveBullAlerts)
this  ===>  doAlerts(PairString,SoundFileBull);
    }

But still I don't get it how the code know which pairs have that conditions because what I understand is that code will save to string PairSting only sentence "BULL PAIRS" how it will put there also that symbols :'( ?
