Coder required for TradingView Pine Script (or Pinescript) indicator -

I need to combine some existing indicators into a strategy. Please include examples of previous Pine Script work in your proposal. Thanks We need to add some horizontal lines into a custom OBV "on balance volume" indicator These horizontal bars are monthly, and they are calculated with the data of the OBV H, L, C of the previous month. We don´t know if this can be done on TV, we have created the bars by hand to give you an example. In the screenshot you will see in top, the bars that we put manually with their corresponding coordinates (this is what the indicator needs to draw) At the bottom how the regular OBV look We have the code for the OBV, you just will need to code the horizontal bars ( we have the formulas for it ) thank you.
