Dear Codersguru,
Could you please help look into my EA below. Its work perfectly fine in backtesting but not on live demo trading account. They is no buy or sell action at all after the crosses. Thank you very much.

extern int Unique_Ref_Number=513;
extern int TakeProfit = 5;

extern double Lots = 1;
extern int Max_Contracts = 1;
extern int emaShortPeriod=5;
extern int emaLongPeriod=13;
extern bool MoneyManagement=true;
extern int Risk=2;

int init() { return(0); }
int deinit() { return(0); }

int Crossed()
{

double emaLong_1=iMA(NULL,0,emaLongPeriod,0,1,PRICE_CLOSE ,2);

double emaShort_1=iMA(NULL,0,emaShortPeriod,0,1,PRICE_CLO SE,2);
double emaShort=iMA(NULL,0,emaShortPeriod,0,1,PRICE_CLOSE ,1);

if (emaShort_1<emaLong_1 && emaShort>emaLong ) return (1); //up trend
if (emaShort_1>emaLong_1 && emaShort<emaLong ) return (2); //down trend

return (0); //no action
}

int start()
{

int total=OrdersTotal();

if(MoneyManagement==true)
{Lotsize=NormalizeDouble((AccountFreeMargin()*Risk/10000),1);}
else
{ Lotsize=Lots; }

SellStopLoss=MathMax(MathMax(MathMax(High[1],High[2]),High[3]),Bid+StopLoss*Point);

if(Time[0]>ordertime && total<Max_Contracts)

{
// check for long position (BUY) possibility
if(Crossed()==1 )
{
OrderSend(Symbol(),OP_BUY,Lotsize,Ask,1,BuyStopLos s,Ask+TakeProfit*Point,"5-13-Long",Unique_Ref_Number,0,Green);
ordertime=Time[0];
return(0);
}
// check for short position (SELL) possibility

}

return(0);

Codersguru,

I need yr help for a MT4 EA.

Day start at 0000 GMT.

1) Draw 5 horizontal lines (different colors). Yesterday OHLC and yesterday (H+L)/2 median line.

2) Sound and pop up alerts when price touches any of the 5 lines.

It would be great if u could help. Thanks...

Many functions are here http://www.forex-tsd.com/general-dis...ing-forum.html

And alert_once thread is here Alert Once (Brain Damage)!

PHP Code:


			
iLow(NULL,0,Lowest(NULL,0,MODE_LOW,1,4)<=0)

Does this say that the Lowest of my indicator (4 bars back) should be less than or equal 0?? If not, how should it be stated?

Dave

Thanks in advance!

that's not right, you can look post 516 on page 52
the way you calculate lowest of indicator is not correct

PHP Code:


			
double lowestFG=9999, highestFG=-9999;//FG short for Forex_Grail, the name of my indicator histogram file.
int currentBar=0;
int endBar=4;
for(currentBar=0;currentBar<endBar; currentBar++)
lowestFG=MathMin(lowestFG, iForex_Grail(Symbol(),0,17,PRICE_CLOSE,currentBar)); //0 = anytime, 17 = maperiod of indicator.

if lowestFG <= 0 then go to next statement

Does this read right??

Dave

When I put this into my EA program, it says the iForex_Grail - function is not defined?? Forex_Grail is the name of my custom indicator.

Maybe it is to be stated: lowestFG=MathMin(lowestFG, iCustom(NULL,0,"Forex-Grail Trade Indicator",period,PRICE_CLOSE,currentBar)); ??
