Convert MQ5 "Heiken Ashi Ma T3 absolutelynolaglwma.mq5" Indicator to Tradingview (Pinescript)

looking only for talented pinescript developers to convert a non lag MA that combined with Heikenashi into pinescript
From what other developers have told me is that the indicator does the following "  'absolutely nolag lwma' ma method takes future bars to backward calculate"
Please dont apply if you know you will not deliver because i can assure you that will be a wastage of your time

Requirements:

Convert the indicator into pinescript

keep the input settings that the indicator has

just FYI

This is place with the conversion challenge

i attach the source codes of 'absolutely nonlag lwma' as below:

for(i=limit; i>=0; i--) prices[i] = iMA(NULL,0,1,0,MODE_SMA,price,i);

for(i=limit; i>=0; i--)

{

for(k=0, sum=0, sumw=0; k<period && (i+k)<Bars; k++) {

weight = period-k;

sumw += weight;

sum += weight*prices[i+k]; }

if (sumw!=0)

lwma1[i] = sum/sumw;

else lwma1[i] = 0;

}

for(i=0; i<=limit; i++)

{

for(k=0, sum=0, sumw=0; k<period && (i-k)>=0; k++) {

weight = period-k; sumw += weight;

sum += weight*lwma1[i-k]; }

if (sumw!=0)

lwma2[i] = sum/sumw;

else lwma2[i] = 0;

}

Please beware that this is where the challenge will be to convert it to pinescript

sum += weight*lwma1[i-k];

this line use future bar's indicator values to backward calculate. 

if any of you developer has solution, he/she will be the right candidate.
