okk understood... one more doubt.. #define FIB_SUP1 "FIB_SUP_1" #define FIB_SUP2 "FIB_SUP_2" #define FIB_SUP3 "FIB_SUP_3" #define FIB_RES1 "FIB_RES_1" #define FIB_RES2 "FIB_RES_2" #define FIB_RES3 "FIB_RES_3" what is the diff of this define and double double A , B , D, E, A1, B1, D1, E1 , A2, B2, D2, E2 ; why need to define... instead of this DEFINE cant do with double FIB_SUP1,FIB_SUP2 ,FIB_SUP3.......... LIKE ? what will happen

{quote} I set that as an example. You see there are 3 objects. Rectangle (your fibonacci SR) and your price labels. From that code, all you have to do is just change the name of the object and the X axis (Date time) and Y axis (price) value. Go read the MQL4 documentation.

Hi, I'm looking for a Trade Management EA that will use an indicator, whose name will be given with a parameter. That indicator will provide a profit target, above the price if a buy is triggered and below the price if a sell is triggered. The Trade Management EA will then have to open a sell/buy order if there is not already a trade opened for the currency pair and the profit target is further than N (parameter) pips from the profit target. The Trade Management EA will manage the opened orders like this: - A new order should be opened each time...

Hi yousername, Thanks for starting this thread, I hope its gets me to learn to do my own stuff one day. I have this indicator I got that extends rectangles on the chart. I use it to label identified support and resistance levels. The good thing it keeps extending automatically into the future. But I would like it to cease to extend once future price has penetrated the rectangle. I checked the code but doing what I want is a little beyond me. Any hints will be appreciated. {file}

  if(Time[0] > mBoxTime)
   {
     for(int i = ObjectsTotal()-1; i >= 0; i--)
       if(ObjectType(ObjectName(i)) == 16)
         ObjectSet(ObjectName(i), OBJPROP_TIME2, Time[0]+MoveBoxRight*500);
      mBoxTime = Time[0];
   }

{quote} Hi Programers! Hi I refer to Post 68 and add 2 screenshots so you have an idea of the indicator working. May I ask anybody tho have a look at the problem of the last 2 bars which from time to time do not plot correcktly (not always, so the code must not be too bad). The shorter TF is ok but the 4H chart does show the problem. I would appreciate your help Thanks Wolfsch{image}{image}
