DYO: McClellan Summation Index example

Summation Index = 1000 + (10%Trend - 5%Trend) - ((10 x 10%Trend) + (20 x 5%Trend))

where:
5%Trend = 39-day EMA of (Advancers-Decliners)
10%Trend = 19-day EMA of (Advancers-Decliners)

The symbol for the Advancers-Decliners is delayed but is available through IB as $ADD.   My question is will it be possible to have this as an espl or will it be possible as as Design Your Own as only the data from $ADD is required.

A:  The following DYO implements the McClellan Summation formula on the daily $ADD chart.
