Pan Priz Challenge FF

Hi guys. I want to show you an indicator available on mql5 (attached), that for me has a great potential. It is Pan Priz indicator (based on polynomial interpolation). My suggestion is to collaborate together to make it better. A good point from where we should start is, in my opinion, trying to improve the main equation coefficients (yellow) because they are what the main curve (orange) is made of:

a2_Buffer[i]=((open[i])+5061600*a2_Buffer[i+1*interval]-7489800*a2_Buffer[i+2*interval]+4926624*a2_Buffer[i+3*interval]-1215450*a2_Buffer[i+4*interval ])/1282975;

...but any other idea is appreciated. The purpose is to make it more accurate, since it is a NO REPAINTING indicator.
I hope that many will be interested like I am in improving this indicator, since as all traders know, a smoothed and accurate price is the key. Here is the chance...

It would be interesting to decrease the period of the result curve (decreasing the other two obviously)...

Hello sir

i try to instal the indicator, but why it doesnt look like the chart above
here's how it look on my D1 chart

i know this is not normal, so could you tell me how to fix it?

also can i have some explanation on how to analyze the prize on when it's gonna go up or down using this pan Priz indicator sir?

thank you
