Help in exiting with ATR readings
Hello to all,
I have a working EA. Not saying it is a profitable EA. It is for experimenting or for a better understanding to this MQL4.
Let's say a sell position is opened at .8555 AUDUSD. 12/15/2009 and that a 20 ATR was calculated day before at .0034. I want to set a stop for 2 times the ATR of the day before plus 1 pip. Which would be .0068 + .0001 + .8555 = .8624 stop.
The following day i would want the EA to recalculate the stop. Not to raise the price of the stop of course, and not to be just a trailing stop either. The EA to recalculate only at the end of each bar.
Hope this is clear enough. If not please contact for further understanding.
Thanks to all who reads this. and hope that this may help others.

Hi,
somehow like this is working. for ATR you need to calculate your formula (2*Atr+1 pip ...). Also Change High[1] to what you need .. Close[1] or else
if (OrderStopLoss()==0||OrderStopLoss()>High[1]+ATR) { OrderModify(OrderTicket(),OrderOpenPrice(),High[1]+ATR,OrderTakeProfit(),0); Print ("Trail Sell by ATR"); continue; }
Thank you EADeveloper,
Most of my day has been researching the correct way to declare the variables. 'pip', ATR, and understanding how to or why the Tester asks for a comma or semicolon at the stoploss declaration.
I will insert a portion of the code below, so as to give a better explaination.
//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
extern double ATR=20; //<<<<<<<<<<By declaring the ATR=20, this would explain
//to the program that I wish the ATR to be calculated by a 20 bar, as oppossed
//to ten or 14 bars.??
double pip=0.0001; //pip -expression on global scope not allowed
extern double StopLoss = 2*ATR+1 pip; //<<< Error, '*' -comma or semicolon expected, Also, the Tester does not like the way I declared the ATR. ATR
expression on global scope not allowed.
//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
I thank you for taking the time to read this much. If you could explain the declarations, I would do further reading to further the coding.
Regards,
Huckleberry
extern double StopLoss = 2*ATR+1 pip;
1<space>pip is not valid code. Use extern only for read only constants to the EA
double ATR=iATR(Symbol(), 0, N, S); // Compute ATR over N bars, S bars ago double SL = 2*ATR + 1*pip;
Thank you WHRoeder,
I was not familiar at all with the SRC button. Now may I can communicate better.
