Creation of NinjaTrader indicator or bot

Hello there 

I would like to create Percentage Hughes Breadth-Momentum Oscillator indicator for Ninjatrader 

Percentage Hughes Breadth-Momentum Oscillator=(H×100)+100=(A−D/A+D+U×100)+100

H represents today’s 1-day ratio of net advances to total issues traded.

A represents the number of advancing issues.

D represents the number of declining issues.

U represents the number of unchanged issues.

A+D+U represents the total number of issues traded each day.

Multiplying today's 1-day ratio of net advances to total issues traded (H) by 100.

Adding 100 to the result of the multiplication.

Adding 100 to the result of the ratio of advancing to total issues traded.

Only bid if you're an expert at this.... Thanks
