Hello Kamilsz,
good job ! i would like to ask you some help, your indicator seems very close to an MT4 version which is not exactly the same and do some repaint but i would like to do the same, do you know how to change your code to get the same please ?
here the part of mt4 code :
int counted_bars=IndicatorCounted();
int i,j,k,limit;
if(counted_bars<0) return(-1);
if(counted_bars>0) counted_bars--;
limit=MathMin(Bars-1,Bars-counted_bars+HalfLength);
if (returnBars) { buffer1[0] = limit+1; return(0); }
if (calculateValue || timeFrame==Period())
{
for (i=limit; i>=0; i--)
{
double sum = (HalfLength+1)*iMA(NULL,0,1,0,MODE_SMA,Price,i);
double sumw = (HalfLength+1);
for(j=1, k=HalfLength; j<=HalfLength; j++, k--)
{
sum += k*iMA(NULL,0,1,0,MODE_SMA,Price,i+j);
sumw += k;
if (j<=i)
{
sum += k*iMA(NULL,0,1,0,MODE_SMA,Price,i-j);
sumw += k;
}
}
double range = iATR(NULL,0,ATRPeriod,i+10)*ATRMultiplier;
buffer1[i] = sum/sumw;
buffer2[i] = buffer1[i]+range;
buffer3[i] = buffer1[i]-range;
//
//
//
//
//
}
}
thanks for your help !
This is great, thankyou very much for sharing.
I'm not aware how price boreder works, mine is rewritten based on https://ctrader.com/algos/indicators/show/295 which is based on TMA+CG mt4 indicator
Hi, is this the same as in MT4 https://www.best-metatrader-indicators.com/price-border-indicator/
Thank you
Its not interpolating.
So more Boilinger style.
Got 2 on my mt4 iam planning to try to get over to ctrade
