i suppose you have declared an array to store all these "mathmax" values
No

This is the correct fix...

//+------------------------------------------------------------------+
//| expert News function |
//+------------------------------------------------------------------+

bool NewsExist()
{

string xmlFileName = Month()+"-"+Day()+"-"+Year()+"-"+Symbol()+Period()+"-"+"FFCal.xml";
bool News;

for(int d = 0; d < ArraySize(Pairs); d++)
{
int MinutesSincePrevEvent =
iCustom(NULL,0,"Economic News",Pairs[d],true,false,false,true,true,1,0);

int MinutesUntilNextEvent =
iCustom(NULL,0,"Economic News",Pairs[d],true,false,false,true,true,1,1);

if(MinutesUntilNextEvent < 60 ||
MinutesSincePrevEvent < 15)
{
News = true;
}
}

int handle = FileOpen(xmlFileName,FILE_BIN|FILE_READ|FILE_WRITE);

if(handle < 0)
{
News = true;
}

FileClose(handle);

return(News);

}

Scooby,

If there is major news for any pair then you hold off on trades? I noticed you search trhough all of the pairs to see if there's news. Whereas Zoog checks for news for a single pair. If I'm reading the code right.

Thanks,
Sandy

Yes.

Reason being that there is allot of dependency with these pairs.

i.e. Any high news affecting USD will probably affect EUR pairs aswell.

Also becaure of the YEN cross pairs any news affecting USD will have an affect on them too because of GBPJPY = GBPUSD & USDJPY.

The downside to this is that you dont get many trades.

apparently, the function MathMax is able to find the maximum value between 2 values only
In order to find the maximum value inside 8 values, I have write like this :

intermedaire1 = MathMax(JpyKgRS,UsdKgRS)
intermedaire2 = MathMax(GbpKgRS,EurKgRS)
intermedaire3 = MathMax(ChfKgRS,AudKgRS)
intermedaire4 = MathMax(NzdKgRS,CadKgRS)
intermedaire5 = MathMax(intermedaire1,intermedaire2)
intermedaire6 = MathMax(intermedaire3,intermedaire4)
MaxKG = MathMax(intermedaire5,intermedaire6)

Is there a less stupid way to write this ???
Inserted Code
MaxKG = MathMax(MathMax(MathMax(JpyKgRS,UsdKgRS), MathMax(GbpKgRS,EurKgRS)), MathMax(MathMax(ChfKgRS,AudKgRS), MathMax(NzdKgRS,CadKgRS)));

Equally nasty just takes up less room.

In the Economic News indicator there is a variable ReportAllForUSD which I've set to true. This should filter out the real earth shakers.

In fact, using KGRs indic (or the code inside my Ea that gives same results) gives OB/OS levels when they reached 80/20 level (or anything else)
I have found that when the market and all pairs are very volatile, it seems to give results in a more narrow range (see the picture, Pink draw), and sometimes the range is wider(blue draw.
My wish is to find at any moment the strongest and weakest currency (and so, only 1 pair). So I first look at the 2 extreme currencies and later do some maths,(I have tried to modify the indic to have something like Stochastic of this indic but I didn't succeded)

Has anyone running Scooby Holy Grail 1.4 or1.6 had any trades today? I haven't had a single one. It's a heavy news day so maybe the filter is saving me from trouble

Thanks!

There is.

Its called studying the underlying economics of a currency.

You could have 1000 technical indicators all saying its a LONG setup only for it to reverse for a number of reasons. i.e. News, Market consolidation, Hedge funds, Trending/Ranging market, Buyers and Sellers.

Example:

You enter a LONG trade on USDJPY and without warning HSBC trading floor decides to sell 100 Million USD cashing in on their previous LONG trades.

This ofcourse is not enough to cause a trend reversal but will blow most retail traders LONG trades and/or accounts.

Dont forget also that your broker may well be trading against your position in the hope of moving the market to your SL's.
