While I like your charting deduction with trend lines. I would consider the idea of using a MACD(30,50,9) to help find bullish/bearish changes. Also adding emas onto OBV helps you stay with the volume trend. Those two changes can help reduce analysis time. But overall it looks good.

Ok! I will add MACD(30,50,9) to the chart. I haven't figured out how to add EMAs to OBV yet. Do you know an indicator that does? I have been testing out Volume "Rate of Change".... Then, I looked at the math formula. It is NOT a really RATE of change formula like in Calculus. It is a linear formula! Most indicators are simple linear formulas with no calculus involved. Anyway, I will test out Volume "Rte of Change" on another platform...since I cannot see that volume on here all the time for some reason.

I have made indicators for both Price and OBV actually. To help get traders seeing the same picture. Yes most are simple linear formulas. What you inadvertently discovered is a branch of mathematics called Numerical Analysis; one of my interests in my Math Major. Was pioneering stuff at one point.

Cool. Just work up an hour ago. Are there any calculus-based indicators? My partner is a calculus genius, and when I show here the math behind the indicators, she disagrees with the formulas. She wants to know how she can understand the markets from a calculus perspective.

Because Price is Stochastic in nature, applying Calculus is rather difficult since the data is non-continuous. One can use Numerical Analysis techniques to process the non-continuous discrete data. Numerical Analysis applies numerical methods to solve differentials and integrals that may or may not be continuous. Finite Differences are the easiest to apply to stock data as well as statistical analysis. If she is looking for more math on the subject, let me know.

Yes.....how do we get this information? She probably will find something different or new. Then, as traders we can have less risk and higher rewards. :)

This is my current GILD chart:
