Help? Converting TdStation indicator to esignal

[specimenfred]

Here's the TS formula for ElderRayAverage

BullPower Average(High - Average(Price,Length),6)
BearPower Average(Low - Average(Price,Length),6)
Plot3 2
Plot4 -2

Price Close
Length 20


Does anyone know how to write this indicator using esignals programming language?

Thanks.

esignal would be something like...

vHavg=study.MAstudy(High() - study.MAstudy(close(),20),6)

vLavg=study.MAstudy(Low() - study.MAstudy(close(),20),6)

maybe someone else could figure out the rest of the efs

Here you go...

I hope this is what you want. I have also uploaded it into my eSignal file share group - Matheny Enterprises
