Ninjatrader Platform Cumulative Delta Indicator Development

I am looking for a developer to create a Ninjatrader platform indicator with OrderFlow package.

The specific indicator functionality I am looking for is Cumulative Delta vs price. The developer shall have access to paid OrderFlow package by him/herself.

The indicator will:
1. show imbalances: different number of buyers/sellers compare to similar price (I will share screenshot)
2. show places where there were many buyers/sellers but the the price didn't go in that direction (absorption)

The indicator should be integrated with my existing trading tools - Ninjatrader 8. The indicator will be in C#. You will share the source code with me and assist with testing and adjustments in case the fake behavior of the indicator will be spotted.

Ideal skills and experience for this project include:
- Proficiency in Ninjatrader platform and OrderFlow package
- Experience in creating custom indicators
- Knowledge of Cumulative Delta vs price
- Knowledge of absorption
- Familiarity with integrating indicators with existing trading tools
