Using Custom Indicator buffer without declaration?
Declare as many as you may likely need but use only as many as necessary.
Thank you for reply.
I am using following code for custom buffer number. But it showing array required error.
int OnInit() { //-----------------------------------------------------------// double CalcDigits = MarketInfo(Symbol(),MODE_DIGITS); { if(CalcDigits == 2 || CalcDigits == 3) CalcPoint = 100; else if (CalcDigits == 4 || CalcDigits == 5) CalcPoint = 10000; } //----Getting buffer data---------------// double top = WindowPriceMax(); double bottom = WindowPriceMin(); double range = floor(MathAbs(top-bottom)*CalcPoint); int buffscale = (int) floor(range / floor(Scale)) * 2; // Total number of buffer used for all type of indicator. double P[10]; // Array declaration with any value at 1st. ArrayResize(P,buffscale,10); // Then resizing it with buffscale //--- indicator buffers mapping for(int sc = 0; sc <= buffscale; sc++ ) { //---- 1st Indicator SetIndexBuffer(sc,P[sc]); SetIndexStyle(sc,DRAW_SECTION,STYLE_SOLID,1,Col1); SetIndexLabel(sc,"Resistance 1"); //---- 2nd Indicator SetIndexBuffer(sc,P[sc]); SetIndexStyle(sc,DRAW_SECTION,STYLE_SOLID,1,Col2); SetIndexLabel(sc,"Resistance 2"); } //--- return(INIT_SUCCEEDED); }
Any correction in this code or any idea to allocate the buffer in reasonable way?
Have you ever looked in the manual what an indicator buffer is and how it works?
Why are you writing code without knowing the basics?
Sorry my bad, I did a serious silly mistake, I overlooked indicator buffer as normal array at 1st.
int OnInit() { //-----------------------------------------------------------// double CalcDigits = MarketInfo(Symbol(),MODE_DIGITS); { if(CalcDigits == 2 || CalcDigits == 3) CalcPoint = 100; else if (CalcDigits == 4 || CalcDigits == 5) CalcPoint = 10000; } //----Getting buffer data---------------// double top = WindowPriceMax(); double bottom = WindowPriceMin(); double range = floor(MathAbs(top-bottom)*CalcPoint); int buffscale = (int) floor(range / floor(Scale)); double P[],N[]; // Array //--- indicator buffers mapping for(int sc = 0; sc <= buffscale; sc++ ) { //---- 1st Indicator SetIndexBuffer(sc,P); SetIndexStyle(sc,DRAW_SECTION,STYLE_SOLID,1,Col1); SetIndexLabel(sc,"1st R"); } for(int sc = 0; sc<= buffscale; sc++) { //---- 2nd Indicator SetIndexBuffer(sc,N); SetIndexStyle(sc,DRAW_SECTION,STYLE_SOLID,1,Col2); SetIndexLabel(sc,"2nd R"); } //--- return(INIT_SUCCEEDED); }
Any Coding example of multi line indicator will be helpful. In this code, above code doesn't have any error. But logically its wrong. Because, its creating multiple buffer but with same array. Here I explain what I actually required to do.
I need P[] buffer also in P1[], P2[] way, each of the P1[] should be in same size buffscale also same number of buffscale. P1[]........Pn[] (n = buffscale)
For example,
If buffscale is 50 then I need indicator buffer array initialize from P1[] to P50[]
How to do that? Using double array buffer?
Thank you in advance.
I figured that I need double array for each indicator type:
So for buffer allocation:
For IndicatorOne[i][ii] where i = buffscale & ii = Indicator Counted() Number of bar index
So I tried coding in following way,
struct dynamic_Buffscale { double IndicatorOne[]; }; dynamic_Buffscale DB[]; int OnInit() { int buffscale = Calculation; int CB = IndicatorCounted(); if(CB<0) return(-1); if(CB>0) CB--; int LT = Bars-CB; //--- indicator buffers mapping ArrayResize(DB,buffscale,1); for(int sc = 0; sc <= buffscale; sc++ ) { ArrayResize(DB[sc].IndicatorOne,LT,0); ArrayInitialize(DB[sc].IndicatorOne,0); //---- 1st Indicator SetIndexBuffer(sc,DB[sc].IndicatorOne); SetIndexStyle(sc,DRAW_SECTION,STYLE_SOLID,1,Col1); SetIndexLabel(sc,"IndicatorOne"); } return(INIT_SUCCEEDED); } // Inside the Oncalculate Part // int limit; int counted_bars=IndicatorCounted(); //---- check for possible errors if(counted_bars<0) return(-1); //---- the last counted bar will be recounted if(counted_bars>0) counted_bars--; limit=Bars-counted_bars; //-----1st loop for Bar index-------------------------------// for(int i=0; i<limit; i++) { Data = Calculation(iOpen(Symbol(), PERIOD_D1,i)); //------------2nd loop --------------------------// for(int ii = 0; ii<= buffscale; ii++) { DB[ii].IndicatorOne[i] = ((newsetbase + floor(Data * Scale)) + (ii*SK))/CalcPoint; } }
Above code shows No Compilation Error . But While adding this indicator on chart showing out of range error at this line
ArrayResize(DB[sc].IndicatorOne,LT,0);
Plus error of No initialization. sc is the buffscale in correct size then whats is the problem here?
Please help I coded upto this.
I have no idea what you are trying to do.
You seem to be mixing structs and buffers.
IndicatorCounted probably is not assigned a value in Init.
I can't make any suggestions because I am totally baffled

Sorry to make you baffled. I am trying my best to explain it to you.
My Indicator counts resulted data for each daily bar & for each daily bar it counts N number of Data (BuffScale). That means I need N number of buffer for each day data.
My Indicator required double array for indicator buffer as it seems.
Indicator[Bar Index][ Buffer Scale aka. N number ]
If Buffscale is 5 then it will allocate like indicator[0,1], [0,2],[0,3],[0,4],[0,5] in following way. for next bar indicator[1,1],[1,2] ....etc.
In side main function we will run loop in following way (Example). Can you please help now? How to setup the array then without stuct
for(int i=0; i<limit; i++) { Data = Calculation with i; for(int j = 0; j<= buffscale; j++) { Indicator[i][j] = Calculation with Data & j; } }

Hi, Generally for using custom indicator buffer, we need to declare it at first in following way.
But in my indicator this number of buffer is not fixed, it calculated with Chart High price & Low price / scale unit. to decide how many buffer it will required to plot data.
So such case how can I do that?
I don't want to draw graphical objects as It will be like a MA. So indicator buffer is my best option.
Please guide.
Thank you
