sjalappat:
Hi,

I am New to MQL4. I don't have much experience in MQL4 and also normal programing.

I required help from seniors.

1st I have done average of 14 days high by mentioning

double high1,high2,high3,...........high13,high14;

high1=high[1];

high2=high[2];

high3=high[3];

...........

............

..................

high14=high[14];

double totalhigh,highavg;

totalhigh=high1+high2+high3+..................high13+high14;

highavg=totalhigh/14;

==================================================

from here onwards, I want help from you to proceed further.

I want to draw line on Indicator filed " highavg " value. simply i want to create an indicator with 14 days average of HIGH. The 14 days average I have assigned to "highavg" variable. So plz help me to code to draw line on indicator filed with the value of " highavg "

First, instead of writing your own indicator for this, you can use the technical indicator supplied by MQL iMA(), but if you want to learn more about programming take a look at Creation of Custom Indicators - Simple Programs in MQL4 - MQL4 Tutorial - you can also find more articles on maling indicators there.

Hey!

Just change this :

Ask - StopLoss,

Ask + TakeProfit,

Bid + StopLoss,

Bid - TakeProfit,

to 0

like this:

Ticket = OrderSend(Symbol(), OP_BUY, LotSize(MM_Risk, StopLoss), Ask, 3, 0,0, "Gap_Trader.B", 101187, 0, Blue);

 

@ Kalenzo thanks thats great.

Do you know why the EA does not open the order with TP and SL?

Is it a problem from my broker?

Hey!

Yes this may be broker problem. Some brokers requires from you to send order without limit levels (tp = 0, sl = 0) and then after the order is succesfully filled, modify it and set TP and SL levels.

Kale

 

Thank you. You mean like this? It dont works, I dont know how.

int Ticket;

if(ToTrade == true && GAP == true)

{

if(CurrOpen < PrevClose)

{

Ticket = OrderSend(Symbol(), OP_BUY, LotSize(MM_Risk, StopLoss), Ask, 3, Ask - StopLoss, Ask + TakeProfit, "Gap_Trader.B", 101187, 0, Blue);

if(ticket>-1)

{

OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES);

OrderModify(ticket,OrderOpenPrice(),TradeStopLoss,TradeTakeProfit,0,Blue);

}

It does not work because in OrderSend function you put SL and TP values instead of 0

 

I dont know it dont work. I'm still amateur.

If you can show me I will be happy.

 

Here is a little code snippet that you may use to open order with ECN broker:

void openOrderECN(double LTS,int type, double sl,double tp, string description = "" )

{

int ticket = 0;

if( type == OP_SELL )

{

while(true)

{

RefreshRates();

ticket = OrderSend(Symbol(),OP_SELL,LTS,MarketInfo(Symbol(),MODE_BID),0,0,0, description ,0,0,Pink);

if(ticket<=0)

{

Print("SELL ORDER ERROR:"+GetLastError());

}

else

{

if(sl>0 || tp>0)

{

OrderSelect(ticket,SELECT_BY_TICKET);

OrderModify(OrderTicket(),OrderOpenPrice(),sl,tp,0,Green);

}

OrderPrint();

break;

}

}

}

else if( type == OP_BUY )

{

while(true)

{

RefreshRates();

ticket = OrderSend(Symbol(),OP_BUY,LTS,MarketInfo(Symbol(),MODE_ASK),0,0,0, description ,0,0,Lime);

if(ticket<=0)

{

Print("BUY ORDER ERROR:"+GetLastError());

}

else

{

if(sl>0 || tp>0)

{

OrderSelect(ticket,SELECT_BY_TICKET);

OrderModify(OrderTicket(),OrderOpenPrice(),sl,tp,0,Green);

}

OrderPrint();

break;

}

}

}

}

 

Where is the worm

Hi,

Here is the beginning of my EA :

extern double Lots=0.01;

extern int TP= 500;

extern int SL= 500;

extern int TP_SL_Increment=100;

extern int Difference=60;

extern double Loss_Lots_Multiply_Factor=2.1;

{

if (l==0){

mtr=1;

GlobalVariableSet("mt_Vager1"+Symbo l()+Period(),mt r);

TP_SL_Inc=TP_SL_Increment;

GlobalVariableSet("l_Vager1"+Symbol ()+Period(),TP_ SL_Increment);

if (OrderSend(Symbol(),OP_BUY,Lots,Nor malizeDouble(As k,Digits),Slippage,NormalizeDouble( Ask-SL*Point,Digits),NormalizeDouble(As k+TP*Point,Digi ts),com,Magic_Number,0,Blue)==-1){

i=GetLastError();

if (i!=1 && i!=0) Alert("Buy Error :"+error(i)+" at "+Symbol()+" "+Period());

}

}

else if (l>0){

if (OrderSend(Symbol(),OP_BUY,l*Loss_L ots_Multiply_Fa ctor,NormalizeDouble(Ask-SL*Point,Digits),Slippage,Normalize Double(Ask-TP_SL_Inc*Point,Digits),NormalizeDo uble(Ask+TP*Poi nt+TP_SL_Inc*Point,Digits),com,Magi c_Number,0,Ligh tBlue)==-1){

i=GetLastError();

if (i!=1 && i!=0) Alert("Buy 1 Error :"+error(i)+" at "+Symbol()+" "+Period());

}else {

TP_SL_Inc=TP_SL_Inc+TP_SL_Increment ;

mtr=mtr+1;

GlobalVariableSet("mt_Vager1"+Symbo l()+Period(),mt r);

GlobalVariableSet("l_Vager1"+Symbol ()+Period(),TP_ SL_Inc);

}

}

}

and I have always the message : "Buy (or Sell) Error : Invalid Stops".

Where is the error ?

Thanks in advance.
