How can I change an Indicator from Close to Open cours
Hallo,
Im a newbie, an hope somebody can help me here to solve
my Problem in Metatrader 4.
I have an Indicator which I use as a filter. But I would like
to change it from close to open to get only open-signals.
I can't find parameters in the code to change it.
So please help me !
Thanks for your effort.
here is the indicator, many thanks

}Calculate the right lot size MQL4/MT4
Hi,
i want to write an ea for the lot calculation i try this.
lot=NormalizeDouble(AccountBalance( )*MaximumRisk/StopLoss/(MarketInfo(Symbol(), MODE_TICKVALUE)),2);
StopLoss is SMA 200.
the problem is now that i don't know how to calculate the diff. betwenn Moving Averange and Open of the Pos. Can someone help me?
double lot=Lots;
double StopLoss=ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);
//---- select lot size
lot=NormalizeDouble(AccountBalance( )*MaximumRisk/StopLoss/(MarketInfo(Symbol(), MODE_TICKVALUE)),2);
How can I say it is Buy or Sell Stopp?
doesn't work. HELP.

doesn't work. HELP.diff = (your_price - sma200_price) / Point
int OrderSend( string symbol, int cmd, double volume, double price, int slippage, double stoploss, double takeprofit, string comment=NULL, int magic=0, datetime expiration=0, color arrow_color=CLR_NONE)
ticket=OrderSend(Symbol(),OP_BUY,1,Ask,3,Ask-25*Point,Ask+25*Point,"My order",16384,0,Green);
for buy stop
ticket=OrderSend(Symbol(),OP_BUYSTOP,1,your_price,3,your_price_SL,your_price_TP,"My order",16384,0,Green);
OP_BUY 0 Buying position.
OP_SELL 1 Selling position.
OP_BUYLIMIT 2 Buy limit pending position.
OP_SELLLIMIT 3 Sell limit pending position.
OP_BUYSTOP 4 Buy stop pending position.
OP_SELLSTOP 5 Sell stop pending position.
it works thank you
need HELP
hi i'm a new EA programmer
i want to make an EA
can someone help me to create it?????
rules:
1. average price = high + low previous day / 2
2. resistance = average price + 20
3. support = average price - 20
4. if price between support and resistance, order buystop on resistance and sellstop on support with TP 30pips and SL on average price, with stop expired on next day
5. if one of the stop is done, cancel the other
thankkkkk
By the looks of it, are you also new to trading?
You're basing an ea on static support and resistance lines, I'm interested on what statistical method you defined those boundaries from?
hi
r u already used that system manually ? and how about performance?
You can learn how to coding with mql here in this forum ,find it I forgot the thread
