grap me:
Hello,
I am just beginner in learning of mql4. I am trying to create a basic supertrend indicator.
I need some expert's help regarding alerts code.


Current Alert Code:
Alert(Symbol() + " (" + Period() + "M) --> " + LSignal + CPri);

Output coming like this:
Symbol Name (15M) --> Buy at 524.55

But, I need stoploss and targets also in the alert based on following simple calculation.

Assume our buy entry at 524.55.

Stoploss : Entry - 1.5% of the stock entry price (524.55 - 7.85 = 516.70)
Target 1 : Entry + 2.5% of the stock entry price (524.55 + 13.10 = 537.65)
Target 2 : Entry + 5% of the stock price (524.55 + 26.20 = 550.75)

(Note: Tick size is 0.05. So if stoploss or target calculation is comes an odd number, need to be rounded to nearest tick size. And if LSignal is a sell signal, need reverse calculation.


Finally I need following output:
Symbol Name (15M) --> Buy at 524.55, SL: 516.70, Target 1: 537.65, Target 2: 550.75


Can somebody please rewrite the code for my requirement?

TY in adv. 
    //Open Price 
      double OP   =524.55;
      double SL_p =1.5;  //Stop Loss % 
      double TP1_p=2.5;  //Take Profit 1 %
      double TP2_p=5;    //Take Profit 2 %
      int d=Digits();    //assumed its the native symbol
      double ts=Point(); //tick size ,assumed its the native symbol
      double SL_size=(OP/100)*SL_p;//open price / 100 , times % ,but thats floaty so ...
      //find how many "points" are in it ,and that must have no decimal points ,so integer
      int how_many_tick_sizes=(int)(SL_size/ts);
      //and then multiply the tick sizes with the points
      SL_size=((double)how_many_tick_sizes)*ts;
      //and then normalize it to have the same digits as the Symbol
      SL_size=NormalizeDouble(SL_size,d);
      //or in short 
      SL_size=NormalizeDouble(((int)(((OP/100)*SL_p)/ts))*ts,d);
      //tp1 in short 
      double TP1_size=NormalizeDouble(((int)(((OP/100)*TP1_p)/ts))*ts,d);
      //tp2 in short 
      double TP2_size=NormalizeDouble(((int)(((OP/100)*TP2_p)/ts))*ts,d);
      //you can add or remove these according to the order type

Heres a calculation example 

Hello all

Could any kind soul write this simple indicator for me?

I need an indicator that draws only 2 horizontal lines, one x ticks above and other x ticks below the current previous bar close price.

I want to develop very simple EA.

    You have only four choices:

can any one help me to Add ALERT when a candle breakout on a Zigzag channel Indicator please.

Comments that do not relate to this topic, have been moved to "Off Topic Posts".

Hi everyone. I'm looking for a simple (adjustable) Keltner channel or bands indicator where I can get an alert any time price crosses either the upper or lower band - doesn't even need to close over/under, just cross that band/channel.

I promise I've looked EVERYWHERE on the internet to see if it already exists - tried one with an alert but didn't work because the alert was on the center/middle line.

If anyone can point me in the right direction, much appreciation to you!
