(NVDA) nVidia "so close"

Custom indicator to track volume against median levels diverting levels of highs and lows. Basically the indicator looks to measure something that offers a view of the direction of shares and whether the shares are pulling or pushing against the price of the stock, or crypto. In this case nVidia is running eerily close to the zero hline. The split is coming up and there will be 10x more shares. Even though the stock split shows definite signs of continued growth and future gains in mcap the timing is correlated as such. The image is on the week length because I couldn't fit the entire image one the day length of time with my computer. The purple line falls as the price gains. The purple line works against the movement of the graph chart in any sense of the word.
