      TrailingStop = 40;

      TakeProfit = 45; 

      InitialStopLoss=33;

    } else    if (Symbol()=="EURUSD") {

      PipsForEntry= 13;

      TrailingStop = 30;

      TakeProfit = 45;

      InitialStopLoss=23;

    } else    if (Symbol()=="USDCHF") {

      PipsForEntry= 13;

      TrailingStop = 30;

      TakeProfit = 45;

      InitialStopLoss=15;

    } else {      

      PipsForEntry= 13;

      TrailingStop = 30;

      TakeProfit = 45;

      InitialStopLoss=30;

    }

If you want to make SL & TP external variables which you can set, you have to comment the above lines of code and uncomment these lines:

PHP Code:


			
/*

extern int PipsForEntry= 5;

extern double TrailingStop = 40;

extern double TakeProfit = 120;

extern double InitialStopLoss=50;

*/

Does anybody know what i would use to limit the number of trades per signal ( i would like 1 trade per signal but am getting like 8 and the last one always is a loser)

Here an EA idea that looks good but i'm sure there's a mistake in the code some where.

SRP= Support, Resistance, Pivot.

entry

using the S & R based on the previous bar and a different TF.
currently the signals are from the 30min TF I have started testing on the 4hr

Anyway if you want to have a look at the EA it's attached.

I think a percentage based exit would work well. one for both buy and sell.

Cheers

I realize an EA can be made w/ multiple time frames, BUT can one be written w/ custom times ? I have an EA w/ MTF but I need custom times not default times so they don't "line up" that often.

Hi guys

How to end a order at the CLOSE of the current bar?

I tried:

if (Close[i] < Open[i])

but it did not work.
i'm totaly rookie in mql.

There is no way to know the last tick of a bar before the next bar opens. The "Close[0]" is always the last know bid, and a new bar starts at the first tick following the timeframe grid.
The first tick of a bar is easier to catch, you can use:
1) Volume[0] == 1
2) Bars() > PreviousBars
3) Time[0] > PreviousTime
The last one is the most reliable and the only one to be used on real account.
I said "most" because it may happen to be also wrong, for example in the case of deconnection. When the connection is retablished you might have lose 5 bars, then the first received bar is the current one, NOT the first missed one. The missed ones are coming after. So the times of the received bars are no more sorted ! Tkx MQ for this very intelligent behavior

.
PS : But its also true that the missed bars are not tradables.

Hi there!!

I'm new to coding and as long as I did some code change in the past I never get to acctually write something from scratch before.

Basically I would like to know how to make a pop up box appear on my chart when I right click with my mouse in a candle.

If somebody knows about a template or some plug already there that does it, I'm pretty sure I can take a look at the code and learn from it

It is possible to create trendline_object which is infinite. But how can I draw line from one point to another?
