Help to create infinite loops in an EEA; Is it possible for a user to change timeframes? - MQL4 and MetaTrader 4

infinite loops in ea init() ?

Is it possible to create infinite loops in the init function of an ea? I have an ea which allows through a socket a user to change timeframes on metatrader. However, the start function is only called when a new tick comes in, i need the socket to come back up immediately, so i decided to create an infinite loop in the init function and the start function.

Will the infinite loop in the init function cause any problems???

Need help to change EA Indicator

I have an EA based on indicator "LSMA" that buy when (red== Empty value && green !=0)

double green = iCustom(Symbol(),0,"LSMA",LSMA_Period,LSMA_Bars,2,1);

double red=...........................

I will now replace LSMA by "SHI_SilverTrendSig1" when red dot is under close.

How can I write that ?

Thanks in advance.

It's very simple. Declare BarsCount in global section with some value - it can be 0, then in init() function put this line of code: BarsCount = Bars;

So at the beginning ea will remember number of bars available on chart, and it will start working only if new one will come.

Help with OrderSend( ) Function

New to mql4, I wrote the following code for practice, but can't figure out why I get an Error 130

I think it has to do with unNormalized numbers. I'm using IBFX broker and they use the 5th decimal on the price.

double Stoploss = 50;

double Takeprofit = 50;

int start()

{

int ticket = OrderSend(Symbol(),OP_BUY,1.0,Ask,3,Ask-Stoploss*Point,

Ask+Takeprofit*Point,"Order #1",1234,0,Red);

if(ticket == -1) Print("error-",GetLastError());

return(0);

}

I also tried setting SL and TP to 500 because of the 5th decimal but got the same error. Any suggestions? Thanks

Error 130 means the Stoploss is invalid, so the value you calculate seems to be out of range.

Check if the value does make sense.

Help using OrderProfit() on Multiple Orders in same currency pair

Hi, I wrote an EA which can trade 1 to 3 Trades at a time on the same currency pair.

The code snippet below seems to calculate the Open Order profits okay but on close they are out by a few percent.

If I run one trade it is accurate.

Can anyone look at the code below and offer any advice?

for ( tradeCount=0; tradeCount < OrdersTotal(); tradeCount++ )

{

if(!OrderSelect(tradeCount,SELECT_BY_POS))continue ;

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol()&&O rderMagicNumber()==MagicNumber01)TradeProfit01 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol()&&O rderMagicNumber()==MagicNumber02)TradeProfit02 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol()&&O rderMagicNumber()==MagicNumber03)TradeProfit03 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol()&& OrderMagicNumber()==MagicNumber01)TradeProfit01 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol()&& OrderMagicNumber()==MagicNumber02)TradeProfit02 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol()&& OrderMagicNumber()==MagicNumber03)TradeProfit03 = OrderProfit() + OrderCommission() + OrderSwap();

}

I would like to be able to read the Profit displayed in the MT4 Account History and display it in an Alert().

Many thanks.
