Multi-Order code?
Does anyone have good code for trading multiple orders when running up against the maxlot barrier?
IE Broker only allows lots of 5, and you want to trade 10, so the function will trade 2 x 5 lot orders instead.
I'm looking for more than just a simple loop here. The problem is that a simple loop will not always fully complete, and you could be left with only a partial order open.
How to take out OrderModify error 1
Hi,
I cannot avoid the OrderModify error 1 : always show up even trying controlling that the data before to modify is different ! I have tried doublenormalize as well...not working...
This is the code:
if (Bid-OrderOpenPrice() >= VPoint*BreakEvenAtProfit)
{
if (OrderStopLoss() != OrderOpenPrice() + BreakEvenShift*VPoint)
{
Vresult = OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice()+ BreakEvenShift*VPoint,OrderTakeProfit(),0,Green);
Any suggestions ?
Thanks.

These aero show on 2 MovingAverage corssing i.e. 5-34, you could find many EAs "MA's Cross EA" search and hopefully you will finde one
How do i set Alert Frequency?
I am new to mq4 and i am trying to creat a display on screen when there is a crossover for MACD. Below is my code but the alerts keep poping up every few minutes.
How can i code it to display alerts only once every hour? Or one alert per bar?
int start()
{
string MACD1="";
color colt9;
double MACDM_S10 = iCustom(NULL, PERIOD_H1, "MACD", 8,17,9, MODE_MAIN, 0);
double MACDS_S10 = iCustom(NULL, PERIOD_H1, "MACD", 8,17,9, MODE_SIGNAL,0);
double MACDM_S11 = iCustom(NULL, PERIOD_H1, "MACD", 8,17,9, MODE_MAIN, 1);
double MACDS_S11 = iCustom(NULL, PERIOD_H1, "MACD", 8,17,9, MODE_SIGNAL,1);
if ((MACDM_S11 < MACDS_S11 && MACDM_S10 < MACDS_S10)) { MACD1="IN UPTREND"; colt9=LimeGreen; }
if ((MACDM_S11 > MACDS_S11 && MACDM_S10 > MACDS_S10)) { MACD1="IN DOWNTREND"; colt9=Red; }
if ((MACDM_S11 > MACDS_S11 && MACDM_S10 < MACDS_S10)) { MACD1="NEW UP CROSSING"; colt9=LimeGreen; }
if ((MACDM_S11 MACDS_S10)) { MACD1="NEW DOWN CROSSING"; colt9=Red; }
string MACD2="";
color colt14;
double MACDM_L10 = iCustom(NULL, PERIOD_H1, "MACD", 12,26,9, MODE_MAIN, 0);
double MACDS_L10 = iCustom(NULL, PERIOD_H1, "MACD", 12,26,9, MODE_SIGNAL,0);
double MACDM_L11 = iCustom(NULL, PERIOD_H1, "MACD", 12,26,9, MODE_MAIN, 1);
double MACDS_L11 = iCustom(NULL, PERIOD_H1, "MACD", 12,26,9, MODE_SIGNAL,1);
if ((MACDM_L11 < MACDS_L11 && MACDM_L10 < MACDS_L10)) { MACD2="IN UPTREND"; colt14=LimeGreen; }
if ((MACDM_L11 > MACDS_L11 && MACDM_L10 > MACDS_L10)) { MACD2="IN DOWNTREND"; colt14=Red; }
if ((MACDM_L11 > MACDS_L11 && MACDM_L10 < MACDS_L10)) { MACD2="NEW UP CROSSING"; colt14=LimeGreen; }
if ((MACDM_L11 MACDS_L10)) { MACD2="NEW DOWN CROSSING"; colt14=Red; }
if(MACD1=="NEW UP CROSSING"&&MACD2=="IN UPTREND")
Alert(Symbol()," - ","H1:"," MACD MAIN UPTREND MOVEMENT"," at ", Bid, " - ",TimeToStr(CurTime(),TIME_SECONDS));
if(MACD1=="NEW DOWN CROSSING"&&MACD2=="IN DOWNTREND")
Alert(Symbol()," - ","H1:"," MACD MAIN DOWNTREND MOVEMENT"," at ", Bid, " - ",TimeToStr(CurTime(),TIME_SECONDS));
if(MACD2=="NEW UP CROSSING"&&MACD1=="IN UPTREND")
Alert(Symbol()," - ","H1:"," MACD, MAIN TREND CHANGE TO UPTREND"," at ", Bid, " - ",TimeToStr(CurTime(),TIME_SECONDS));
if(MACD2=="NEW DOWN CROSSING"&&MACD1=="IN DOWNTREND")
Alert(Symbol()," - ","H1:"," MACD, MAIN TREND CHANGE TO DOWNTREND"," at ", Bid, " - ",TimeToStr(CurTime(),TIME_SECONDS));
return(0);
}
in what pairs?
